Full textAbstract:
Electroplating is considered to be a major polluting industry because it discharges toxic materials and heavy metals through effluent like wastewater, air emissions and solid wastes. There are many registered electroplating units in Mumbai Metropolitan Region (MMR). The quantities of gaseous wastes generated from these industries were estimated and the existing control and treatment techniques for these gaseous wastes were evaluated. Further, Air Quality Modeling (AQM) study was also carried out to predict the concentration of acid mist with the help of emission, characteristics of stack and meteorology. A Gaussian plume model based SCREEN View software was used to predict concentrations for two industries which showed that the acid mist emissions from stack were under the consented limits. Further, health impact survey was performed at 1km radius of the industry to study the effects of air pollution on human health. It showed that 47%, 40% and 57% workers near the electroplating industries are suffering from chest pain, eye irritation and breathlessness respectively. Clustering of electroplating industries in the MMR will improve the waste management in the region. Installation of efficient air pollution control equipment like wet scrubbers can eliminate the hazards caused due to acid mist emissions from electroplating industries.

Full textAbstract:
To analyze the impact of the added value of primary, secondary, and tertiary industry on public attention to air pollution in Handan, Xingtai, and Shijiazhuang, Baidu index is used to build the air pollution attention index. Taking the added value of the primary, secondary, and tertiary industry as the influencing factors, fractional grey multivariable convolution model is used to predict and analyze the public attention to air pollution in these three cities from 2020 to 2024. The results show that the secondary industry has the greatest impact on the public’s attention to air pollution compared with the primary industry and the tertiary industry. And the added value of the secondary industry with faster increase will cause a faster increase in the public’s air pollution attention from 2020 to 2024, especially in Handan. It is not only helpful to air pollution control, but also helpful in solving the public psychological problems caused by air pollution.

Full textAbstract:
During the 1960s, Sarnia was the wealthiest city in Ontario and the one with the dirtiest air. Its economy was dominated by Chemical Valley, the city’s petrochemical industry. Chemical Valley firms and executives were civically active, donating to public causes, dominating the local chamber of commerce, and working closely with provincial and municipal officials to ensure a friendly business environment. They also maintained a monopoly on information about local air pollution levels and were not required by government to adhere to clean air regulations. However, like the rest of the chemical industry at the time, Chemical Valley was exposed to an onslaught of negative publicity, raising the threat of regulation and loss of their control over emissions data and production processes. This article illustrates how economic elites in Sarnia prevented the problematization and regulation of air pollution. In doing so, it describes the actors in the policy system and examines its recourse to suppress dissent when activists sought to raise the air pollution issue.

There is an upsurge in air pollution due to urbanization and industrialization across the globe. This calls for immediate action. Large exterior surfaces of high-rise buildings and civil infrastructure can be utilized to one’s advantage by applying nanocoatings that are capable of alleviating the concentration of air pollutants in the surrounding atmosphere. Few nanomaterials with their photocatalytic property can degrade some of the air pollutants such as oxides of nitrogen (NOx) and sulfur (SOx) to their respective non-harmful counterparts, thereby bringing down the concentration of actual pollutants. Most of the metropolitan cities which have high-rise buildings are the ones that have more concentration of pollutants. Therefore, these buildings can be employed for coating nanomaterials on the exterior surface of these buildings. Nano-photocatalysts can be either incorporated onto a surface as a coating or into the outer layer of the building during construction. The most commonly used semi-conductor nano-photocatalyst for this purpose is nano titanium dioxide (TiO2) or its composites, such as silica-doped TiO2. This review paper consolidates various methods of synthesizing TiO2 and its composites, their characterization, different methods of incorporating nanomaterials onto construction materials, and degradation mechanism.

Full textAbstract:
This paper addresses the importance of the prevention air pollution from ships in terms of international legal compliance and enforcement. In addition to effectively enforcing international norms, standards and procedures, flag States have an obligation to prevent polluting ships from sailing. The International Convention for the Prevention of Pollution from Ships (MARPOL) has been described by the International Maritime Organization as “the most ambitious international treaty covering maritime pollution ever adopted”. Annex VI of the MARPOL allows for the establishment of Emission Control Areas (ECAs). ECAs have been implemented to reduce the amount of air pollution from ships. The new ECA regulations entered into force on the 1st of January 2015. First and foremost, this paper examines some aspects of the implementation of the new ECA regulations on shipping industry and control air emissions in the Baltic Sea ECA. Moreover, it outlines that Port State Control and Flag State Control are commitment to monitor and enforce compliance through inspections and penalties.

The release of toxins occurs from a multitude of sources both with and without air pollution control. These sources have become of more concern. The value of pollution control for toxicants can be addressed from a risk benefit methodology. The risks can be estimated from the Air Emission Risk Assessment Model (AERAM), a computerized methodology developed by EPRI for the electric utility industry, used to assess cost-benefit trade-offs for various control techologies. This methodology considers particle-size class emissions, dispersion, and health impacts, and has been used to evaluate trade-offs for fuel switching at a coal-fueled electric-power generating station in the Northeastern United States.

The Chinese government has implemented a number of environmental policies to promote the continuous improvement of air quality while considering economic development. Scientific assessment of the impact of environmental policies on the relationship between air pollution and economic growth can provide a scientific basis for promoting the coordinated development of these two factors. This paper uses the Tapio decoupling theory to analyze the relationship between regional economic growth and air pollution in key regions of air pollution control in China—namely, the Beijing–Tianjin–Hebei region and surrounding areas (BTHS), the Yangtze River Delta (YRD), and the Pearl River Delta (PRD)—based on data of GDP and the concentrations of SO2, PM10, and NO2 for 31 provinces in China from 2000 to 2019. The results show that the SO2, PM10, and NO2 pollution in the key regions show strong and weak decoupling. The findings additionally indicate that government policies have played a significant role in improving the decoupling between air pollution and economic development. The decoupling between economic growth and SO2 and PM10 pollution in the BTHS, YRD, and PRD is better than that in other regions, while the decoupling between economic growth and NO2 pollution has not improved significantly in these regions. To improve the relationship between economic growth and air pollution, we suggest that the governments of China and other developing countries should further optimize and adjust the structure of industry, energy, and transportation; apply more stringent targets and measures in areas of serious air pollution; and strengthen mobile vehicle pollution control.

PM2.5 pollution-related diseases lead to additional medical expenses and the loss of working hours, thus affecting the macro-economy. To evaluate the health-related economic impacts of PM2.5, the Integrated Assessment Model of Climate, Economic, and Environment (ICEEH), combined with the Computable General Equilibrium (CGE) model, the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model, and a health impact assessment module was constructed. The impact of different air pollution control strategies was analyzed in Guangdong Province by establishing a Without Control (WOC) scenario, an Air Control (AIC) scenario, and a Blue Sky (BLK) scenario. The results show that in the WOC scenario for 2035, the death rate for Guangdong Province is 71,690 persons/year and the loss of working hours is 0.67 h/person/year. In the AIC and BLK scenarios compared with WOC for 2035, the loss of working hours is reduced by 29.8% and 34.3%, and premature deaths are reduced by 33.0% and 37.5%, respectively; GDP would increase by 0.05% and 0.11%, respectively, through strict pollution control policies. Furthermore, improved labor force quality induced by better air conditions would promote the added value in labor-intensive industries, such as agriculture (0.233%), other manufacturing (0.172%), textiles (0.181%), food (0.176%), railways transport (0.137%), and services (0.129%). The added value in the waste (−0.073%), nature gas (−0.076%), and crude oil sectors (−0.072%) would decrease because of the increased investment installment in PM2.5 treatment equipment.

Full textAbstract:
To continuously improve air quality, after implementation of the “Clean Air Action Plan, 2013–2017” (CAAP), the “Three-year Action Plan to Fight Air Pollution” (TYP) was further conducted from 2018 to 2020. However, the effectiveness of the TYP remains unclear in one of the major city-clusters of China, the Sichuan Basin. In this study, the bottom-up method was used to quantify the emission reduction during TYP based on the emissions inventory in Sichuan Basin in 2017 and the air pollution control measures adopted from 2018 to 2020 in each city. The reduction of PM2.5 concentration and the avoided premature deaths due to implementation of air pollution control measures were assessed by using an integrated meteorology and air quality modeling system and a concentration-response algorithm. Emissions of SO2, NOx, PM2.5, and VOCs in the Sichuan Basin have been reduced by 42.6, 105.2, 40.2, and 136.6 Gg, respectively. The control of non-electricity industry contributed significantly to the emission reduction of all pollutants, accounting for 26–49%. In addition, the control of mobile sources contributes the most to NOx reductions, accounting for 57%. The results illustrate that the focus of air pollution control in Sichuan Basin is still industrial sources. We also found that the emission reduction of NOx, PM2.5, and VOCs in Chengdu is significantly higher than that of other cities, which were about 3.4~15.4 times, 2.2~40.1 times, and 4.3~24.4 times that of other cities, respectively. In Sichuan Basin, the average reduction rate of PM2.5 concentration due to air pollution control measures was 5% on average, with the highest contributions from industry, mobile source, and dust emission control. The decrease rate in each city ranges between 1~10%, and the decreasing ratios in Dazhou (10%), Chengdu (8%), and Zigong (7%) are relatively higher. The number of premature deaths avoided due to air pollution control measures in Sichuan Basin is estimated to be 22,934. Chengdu and Dazhou have benefitted most from the air pollution control measures, with 6043 and 2713 premature deaths avoided, respectively. Our results indicate that the implementation of TYP has achieved remarkable environmental and health benefits.

Abstract In our day-to-day life, environmental degradation and global warming are essential factors to consider. These problems were caused due to the contamination of water, air, and soil with the waste generated by industries. The pollutants level generated by the industries to be measured and controlled by central and state pollution control board. The air pollutants are the major cause for the deterioration. The existing pollutant monitoring system are complicated, inaccurate, unreliable, delayed intimation and less efficient. Hence in mettur thermal power plant, the internet of things-based pollutant gas monitoring system has been implemented. This system consists of numerous gas sensors, Arduino UNO controller, ESP8266 Wi-Fi module, ubidots server and alarm. The pollutants measured are carbon monoxide (CO), suspended particulate matters (SPM), sulphur oxides (Sox), nitrogen oxides (Nox) in air. When the pollutants level of industry is crossed the limit, the pollution control board has been intimated the exact location of the industry through internet. The pollution control board can automatically send alert SMS and email to the respective industry. This system is suitable for the recent technology industrial internet of things. The electrostatic precipitator has been installed for pollutant control. It is proved that the proposed system is a very good replacement for the conventional monitoring system done by the human. It is acted as user friendly interface for the operation of the system and is reliable. The system has attained improved pollutant control, increased stability, and consistency of the power plant and finally the safety of the employees working in the power plants and mine areas.

In recent years, air pollution events have occurred frequently in China and have had serious impacts on people’s work and life. The research objective of the article is to find out the spatial effects of green process innovation, environmental regulation, rainfall, and pollution from industrial development on air pollution by compiling a development index of the air pollution industry and constructing spatial autoregression and spatial Durbin models. The study found that green technology innovation significantly reduced sulfur dioxide emissions and fog haze pollution. The development of industrial air pollution is an important source of sulfur dioxide and pollutant haze and has significant spatial spillover effects. The strengthening of environmental regulations leads to a decrease in life pollution but causes a transfer of industrial pollution. Rainfall is conducive to reducing the concentrations of pollutants in the air, such as those from chimneys and smog. Policy recommendations are proposed, such as establishing different environmental policies for different green technological innovations to promote green technology innovation; constructing a joint defense control system for regional air pollution; increasing the construction of artificial wetlands in areas with serious air pollution; and creating scientific plans to coordinate the development of industry, technology, and the environment, to provide help for China to reduce the emission of atmospheric environmental pollutants.

China has been the largest vehicle market in the world since 2009. The stalemate between the rapid development of the vehicle industry and delayed vehicle emission control has become increasingly prominent. Vehicle emission has become a significant source of air pollution in China’s cities. Understanding the current barriers in the vehicle industry is necessary for the development of effective and sustainable measures and policy to manage vehicle-induced air pollution. This review provides insight into the circumstances and causes of vehicle-induced air pollution and outlines recent progress in policy-makers’ long-term strategies and regulations. The development of an integrated mechanism of social participation, technical revolution, and regulatory innovation in vehicles, fuel, and roads is suggested to break the stalemate between air pollution and the automobile boom in China; the implications of this review extend to other countries facing the similar atmospheric pollution problems.

A new regulatory system known as integrated pollution control (IPC) is being introduced in the UK over the period 1991-1996. This will apply to combustion processes, some coating processes and some pulp and paper mill processes. Prescribed processes will have to use control concepts based on “best available techniques” and optimisation of waste streams released to the different receiving media. BAT standards have been set for the combustion processes, but not yet for the pulping and papermaking processes. The main types of UK mill that could be affected by this new regime are non-integrated paper mills, which use imported pulp and/or wastepaper. If prescribed under IPC, mills will have to justify their raw materials/process selection and pollution abatement technologies in terms of minimising impacts to air, water and land.

The air-pollution control system of a lead-acid-battery recycling industry was studied. The system comprised two streams with gravity settlers followed by filter bags for the factory indoor air and the metal-recycling furnace, respectively. Efficiency in particle removal according to mass was found to be 99.91%. Moreover, filter bags and dust from the gravity settlers were analyzed for heavy metals by Wavelength Dispersive X-Ray Fluorescence. The results showed high concentrations of Pb and Na in all cases. In the filter bag samples from the indoor atmosphere stream, Ca, Cu, Fe, and Al were found in concentrations higher than that in the filter bag samples from the furnace stream. The opposite was found for Na. Tl and K were only found in furnace stream bag filters. The elemental concentration of the dust from the furnace fumes stream contained mainly Fe, Na, Cd, Pb, Sb, and Cl, while the indoor main stream contained mainly P, Fe, Na, Pb, and Sb. In all cases, impurities of Nd, Ni, Rb, Sr, Th, Hg, and Bi were found. The high efficiency of the air-pollution control system in particle removal shows that a considerable reduction in emissions was achieved.

Full textAbstract:
located in the west of Sichuan Basin and composed of Chengdu City, Mianyang City, Deyang City, Ziyang City, and Meishan City, Chengdu urban agglomeration is an area where industry, population and motor vehicles are densely distributed. Therefore, there are acute conflicts between the economic development and atmospheric environmental protection. On one hand, lots of pollutants emitted by industry and motor vehicles enter the atmosphere and adversely affect the environmental air quality. On the other hand, the dense population needs good air quality. Since the current environmental air quality standards cannot fully protect human health and ecological balance, in the calculation of the atmospheric environmental capacity for urban agglomerations, in addition to pollution control investment and environmental quality up to standards, the pollution hazard losses should also be considered. In the present paper, according to the specific conditions of Chengdu urban agglomeration, a multi-source mode and dual-objective optimized atmospheric environmental capacity model was developed with the minimum pollution control investment and pollution hazard losses serving as the objective function and the environmental air quality up to standard serving as the constraint. The Sulfur Dioxide atmospheric environmental capacity of Chengdu urban agglomeration was calculated by using this model so as to provide basic data for the total capacity control of Chengdu urban agglomeration.

This paper systematically summarizes the hierarchical cross-regional multi-directional linkage in terms of air pollution control models implemented in the Beijing-Tianjin-Hebei urban agglomeration, including the hierarchical linkage structure of national-urban agglomeration-city, the cross-regional linkage governance of multiple provinces and municipalities, the multi-directional linkage mechanism mainly involving industry access, energy structure, green transportation, cross-regional assistance, monitoring and warning, consultation, and accountability. The concentration data of six air pollutants were used to analyze spatiotemporal characteristics. The concentrations of SO2, NO2, PM10, PM2.5, CO decreased, and the concentration of O3 increased from 2014 to 2017; the air pollution control has achieved good effect. The concentration of O3 was the highest in summer and lowest in winter, while those of other pollutants were the highest in winter and lowest in summer. The high pollution ranges of O3 diffused from south to north, and those of other pollutants decreased significantly from north to south. Finally, we suggest strengthening the traceability and process research of heavy pollution, increasing the traceability and process research of O3 pollution, promoting the joint legislation of different regions in urban agglomeration, create innovative pollution discharge supervision mechanisms, in order to provide significant reference for the joint prevention and control of air pollution in urban agglomerations.

AbstractThe petroleum refining industry has a significant influence on the total pollution of the environment by industrial discharges and wastes. In the operation of petroleum refineries, the atmosphere is polluted with hydrogen sulfide, sulfur dioxide, nitrogen oxides, carbon monoxide, hydrocarbons, and other toxic substances. The main pollutants are sulfur dioxide and hydrocarbons. The fresh water used by refineries in product cooling is returned to the original source of water containing crude oil, petroleum products, and mineral salts as contaminants. The extent of air and water pollution depends on the particular processing technology, control measures that are employed and also on the scale of the processing. In working out these measures, the primary attention of scientific-research institutes and design and planning organizations must be directed not only towards how to reduce the contaminating and poisoning action of industrial discharges on the environment, but primarily towards preventing or minimizing these discharges in the refineries.

Air pollution stems gases and air borne particles which, in excess, are harmful to human health, buildings and ecosystems. Air pollution in developing countries is derived not only from stack emission of pollutants from relatively large industries, where inadequate pollution control measures exist and pollutants are allowed to escape to atmosphere. The kind of air pollution emitted vary from industry vary from industry to another, the concentrations of different pollutants in the atmosphere also vary widely from process to process, and from place to place with different geographic and climatic conditions.. In general, the workplace exposure levels are much higher than that the general population, because the emissions are rapidly diluted and dispersed by the wind. But the exposure duration of the general population is much longer than that of workers. Air pollution is the presence of substances in air in sufficient concentration and for sufficient time, so as to be, or threaten to be injurious to human, plant or animal life, or to property, or which reasonably interferes with the comfortable enjoyment of life and property. Air pollutants arise from both manmade and natural processes. Air pollutants arise from both manmade and natural processes.

The widely used herbicide, dimethylamine salt of 2,4-dichlorophenoxy acetic acid (2,4-D-DMA), is usually prepared by mixing a dimethylamine (DMA) aqueous solution with a solid 2,4-dichlorophenoxy acetic acid (2,4-D). The vapors of the both, reactants and products, are potentially hazardous for the environment. The contribution of DMA vapors in overall pollution from this process is most significant, concerning vapor pressures data of these pollutants. Therefore, the control of the air pollution in the manufacture and handling of methylamines is very important. Within this paper, the optimal air pollution control system in preparation of 2,4-D-DMA was developed for the pesticides manufacturing industry. This study employed the simple pollution prevention concept to reduce the emission of DMA vapors at the source. The investigations were performed on the pilot plant scale. To reduce the emission of DMA vapors, the effluent gases from the herbicide preparation zone were passed through the packed bed scrubber (water scrubbing medium), and the catalytic reactor in sequence. The end result is a substantially improved air quality in the working area, as well as in the urbanized areas located near the chemical plant.

China has achieved tremendous economic development in the past 30 years. However, the extensive way of developing the economy has also caused a certain degree of environmental pollution, such as air pollution caused by coal burning, especially in the Beijing-Tianjin-Hebei region. To solve this problem, China has made a series of policies to tackle the severe air pollution in this region. Although those policies are effective, they have also led to some social problems. This phenomenon has caught the attention of researchers. This paper aims to study the consequences of environmental policies on the Beijing-Tianjin-Hebei region and how to alleviate the negative impact of those environmental policies. Through analyzing the data of industrial structure in the past eight years, it is found that the pillar industry of this region is the secondary industry. China's designated environmental policies have increased the cost of taxes, basic materials, energy conservation and emission reduction equipment for small and medium-sized enterprises in the second industry, resulting in the decline of profits and even bankruptcy of small and medium-sized enterprises and causing the recession of the second industry and economy recession. It has led directly to the decline of manufacturing, higher unemployment and increased competition between The Beijing-Tianjin-Hebei region. This paper tries to provide some countermeasures and suggestions to Hebei province's social and economic problems, such as rising unemployment and recession. Finally, it analyzes the latest national air governance policies and the changes in industrial structure brought about by sustainable energy in the future, trying to solve the problem of worker unemployment caused by air policies through the development of green industries.

The air and soil quality in the vicinity of cement industry influences the soil properties and distribution pattern of plants. Sensitive plant species are abolished from such areas, however, only pollution tolerant species survive under stress conditions. In this study, the potentially toxic metal pollution in soil and Air Pollution Tolerance Index (APTI) of plants occuring nearby the cement industry, Bhagwanpur (Haridwar) were evaluated. Four biochemical parameters such as leaf relative water content (RWC), ascorbic acid (AA) content, total leaf chlorophyll (TCh), and leaf extract pH were used to develop an APTI. It was found that the soil in the vicinity of cement industry was having high concentrations of potentially toxic metals in comparison to control but within the permissible limits as per international standards. Twenty four plant species growing near a cement factory, an air pollution point source, were collected and analysed for APTI. The APTI was found in the range of 10.68 to 43.50. Cyperus rotendusand Cynodon dactylon were found to be having high APTI. The results highlighted the need for regular monitoring of potentially toxic metals in soil and APTI measurements to be conducted throughout the growing season.

Background: In present scenario industrialization is growing at a faster rate throughout the world in developed as well as developing countries. Occupational lung disease is becoming one of the major problem in occupational health. Many environmental problems are associated with textile industry such as water pollution, noise pollution, soil pollution and air pollution. Out of these different pollutions air pollution resulting from cotton dust is the most important factor affecting health of the workers. Various studies in India and outside have been carried out in cotton mill workers with different results. So present study was planned to evaluate the lung function of cotton mill workers by spirometry in this part of country.
Material & methods: The study was carried out in 55 participants who were exposed to cotton dust directly. 55 controls were also selected from the workers of same mill but not exposed directly to cotton dust. Spirometry findings were compared between two groups.
Results: The values of most of the PFT parameters were significantly reduced in subject group compared to control group (p<0.05). However there was no any significant difference in the values of FEV1/FVC ratio between the groups (p>0.05).
Conclusion: From our study we conclude that workers in the cotton mills are exposed to cotton dust and various types of other air pollutants. And the chronic exposure results in decline in pulmonary function

Coal-dependent industries are the economic pillar of many countries; however, their contribution to air pollution also restricts long-term economic development. While the negative effects of environmental regulations on coal-dependent industries has attracted much attention, the health effects of such regulations remains barely quantitatively studied. Our study is based on a quasi-natural experiment created by a command-and-control policy in China’s cement industry, whereby cement enterprises are forced to stop production for a specific period of time every year. This paper adopted DID methods and found that direct pollution control measures for coal-dependent industries could significantly improve residents’ health levels and that the resultant reduction in medical expenditures could save 456.8 RMB yuan per capita per year. Additionally, our mechanism analysis found that the COPP is beneficial to residents’ health in that it reduces air pollution and sewage treatment rates. This means that pollution from coal-dependent industries has a large and underestimated impact on residents’ health. Environmental regulation of the coal-dependent industry could greatly improve the health of residents.

Amid sawmill busy lives, air pollution is one of the greatest casualties of our time and has increased worldwide since 1990. Today, the history of air pollution in sawmills accounts for 93.32% of the total number of wood processing industries in Nigeria, it seems daunting, overwhelming and have positioned the country at a perilous crossroad. For emerging nations such as Nigeria with a population projected to hit 410.6 million humans by 2050 with up to 40-60 million people with mental disorders at the moment, consequently more than 40,000 deaths a year will be due to air pollution. 7 million deaths worldwide is attributed to air pollution with the number set to increase significantly in coming decades mostly through non-communicable diseases like lung cancer, stroke and chronic obstructive pulmonary disease but also through acute respiratory infections like pneumonia. Similarly, around 90% of all people breathe air contaminated with pollutants. In 2015, tobacco caused 7 million deaths, 1.2 million AIDS, 1.1 million cases of tuberculosis and 0.7 million of malaria, 19% of all cardiovascular deaths, 24% of all deaths due to ischaemic heart disease. 21% of stroke deaths, and 23% of deaths from lung cancer. Non-communicable diseases are responsible for 70% of deaths from air pollution and are a major cause of unexplained infections. In addition, air pollution seems to be significant but it is still not a determinant factor of the risk of neurodegenerative disorders in children and neurodegenerative diseases in adults. This study assessed ambient air quality in major sawmill sites in Ilorin Metropolis, Kwara State, Nigeria. Air pollution measurements were made using direct reading through automatic in situ gas monitors; Hand held mobile multi-gas monitor with model AS8900 (Combustible (LEL), and Oxygen (O2)), BLATN with model BR—Smart Series air quality monitor (PM10, Formaldehyde) and air quality multimeter with model B SIDE EET100 (Dust (PM2.5), VOC, Temperature and Relative Humidity). The results show that the mean concentrations of CO, O2 and other measured parameters such as Formaldehyde (HcHo) etc., are commonly lower and within acceptable range of National and International regulatory standards for air quality indices. There are however some exceptions such as mean concentrations of Volatile Organic Compounds (VOCs), PM2.5, PM10 and Combustible (LEL) respectively high when compared to National and International standards. This high value is attributed to the amount of pollutant present in the sawmills due to the input of influents it receives from activities of the sawmill. This is why there has been air pollution in Ilorin metropolis and were however, found to be polluted. Given the high cost of additional measures to lessen air pollution and the new perspectives suggesting that health effects can be observed at low concentrations, the health effects of air pollution should be of scientific and regulatory interest in coming years. In the absence of aggressive control, ambient air pollution is expected to cause between 6 and 9 million deaths a year by 2060.

The impact of modernization in the industrial sector has the potential to produce waste as residual products that can pollute the environment, damage and / or endanger health and the environment. Actualization of these threats is contrary to the ecologically Sustainable Development Principle which requires preservation of functions and controlling environmental pollution and damage. The disposal of waste from the production of krupuk Home Industry in Kenanga Village, Sindang Subdistrict, is channeled into a river which is a source of water for the community, causing river pollution. This research is a normative juridical research, based on normative analysis, legal science approach. Primary data as the main data is obtained from various legal materials related to research, supported also by secondary and tertiary data as additional data. The results showed that the implementation of Indramayu Regency Regional Regulation Number 9 of 2012 concerning Water Quality Management and Water Pollution Control, has not been implemented properly. This is evident from the existence of river pollution which is the source of water in Kenanga Village, Sindang Subdistrict, Indramayu Regency, which can no longer be used for people's daily lives due to the waste of krupuk production. The legal responsibility of cracker producers in the management of production waste as stipulated in Article 28 of Indramayu Regency Regulation Number 9 of 2012 concerning Water Quality Management and Water Pollution Control, which is subject to administrative sanctions in the form of a written warning, is deemed not to have a deterrent effect

Crumb rubber is one of Indonesia’s agroindustry export commodities. This industry faces environmental problems due to their wastes, both liquid and air. The source of air pollution is commonly from drying process that emitted odor from its evaporation and heating phenomena. Industry uses wet scrubber technology as air pollution control from emitted odor from drying process. Preliminary identification in noncontrolled wet scrubber shown that wet scrubber efficiency around 47%. Low efficiency wet scrubbing process causes rain drop of water vapor around drying process. This research used electrochemical based sensor MICS 5524 as ammonia monitoring instrument, assisted with arduino as microcontroller to regulate water discharge through valve controlling scrubbing process. This electrochemical based sensor reads ammonia based on voltage reads by Arduino microcontroller. Ammonia reading then control scrubbing process by adjusting valve opening for spray water distribution. Wet scrubber efficiency increases to 66,96% due to water scrubbing control, also can save water utilization as high as 61,90%, followed by absence of rain drop contains ammonia around drying process area.

Air pollution is one of the major environmental problems with short, medium and long-term effects. Substances emitted into the atmosphere (CO2, SO2, NOx, PM10) contribute to the amplification of the effects of climate change, acidification, air quality deterioration. The most important sources of PM10 emissions come from commercial, institutional and household sectors, industrial processes, road transport and agriculture. In order to protect the atmosphere and improve air quality, are needed measures of control at pollutant emissions. Early pollution reduction actions have led to a significant decrease of PM10 emissions especially from the production and distribution of energy, combustion processes and road transport has significantly diminished. Improving air quality requires continuous monitoring of emissions and, in particular emissions of particulate matter/ PM10. The paper presents the results of the monitoring activity of particulate matter/ PM10 from the thermo-energetic industry. The results of the monitoring include the particulate matter/ PM10 values in the range (68.083 mg/Nm3 - 93.166 mg/Nm3), values that do not exceed the emission limit values.
