Full textAbstract:
Since independence, Indian policymakers have attempted to address environmental problems by passing a number of rules and regulations as per the vision of the constitution and in response to the requirement of time. However, due to the prevalent poverty and the developmental compulsions of the nation, environment and its protection was not a priority of the government till the end of the 1960s. But, the 1972 Stockholm Conference on Human Environment brought a marked shift in India’s approach to environmental issues. The conference proved to be a turning point in India’s perception on environment and facilitated the creation of the National Committee on Environmental Planning and Co-ordination (NCEPC) in 1972. The NCEPC triggered a rise in environmental legislation, beginning with the Water (Prevention and Control of Pollution) Act of 1974, which provided for the creation of Pollution Control Boards for the control of water pollution at national and state levels and empowered them to enforce the law. The boards were later empowered to deal with air pollution by Air (Prevention and Control of Pollution) Act of 1981 and acted as regulatory mechanisms to environmental protection. This article primarily deals with the role of the Central Pollution Control Board as a regulatory authority to environmental protection and regulations in India.

Central Pollution Control Board guidelines and court directions are yet to achieve the desired result of keeping rivers and lakes free of polluting heavy metals and PoP used in idols. As Durga Puja and Dussehra festivities conclude, rivers and lakes once again became more polluted following immersion of idols worshipped in puja pandals across cities. The guidelines formulated by the Central and state pollution control boards (CPCB and SPCBs) went largely unheeded in spite of some efforts by municipal bodies and police to curtail the practice. Environmentalists and river experts have been campaigning against these idol immersions for over a decade now. Judicial interventions in the past, however, have not yielded the desired result. Every year, after Ganesh Chaturthi, Durga Puja and Kali Puja, the biological oxygen demand (BOD) levels in rivers increase dramatically.

Noise is generally defined as the unwanted sound produced by various natural or man-made sources such as construction, industrial, transportation activities etc. Noise can have many adverse effects such as hearing impairment, sleep disturbance, interference with speech and communication, reduced performance, annoyance and harming physiological functions. In India, the permissible noise level for different areas is laid down by Central Pollution Control Board (CPCB). Lucknow city, one of the major urban centres of Uttar Pradesh, has a population around 28 lakh according to Census, 2011. This huge number of people contributes significantly in the increasing levels of noise and, therefore, creates an alarming state of noise pollution. This paper aims to study the growing noise level trends in the city, analyse the average sound levels to ascertain the status of ambient noise levels and recommend suitable preventive measures. The data used for substantiation has been drawn from the reports of Central Pollution Control Board (CPCB) and Uttar Pradesh Pollution Control Board (UPPCB). Microsoft Excel software has been used for tabulation and graphical representation of data while ArcGIS 10.3 software has been used for the cartographical representation.

Abstract Bangalore is a city in the Indian state of Karnataka. Many public sector businesses and R&D organisations, such as Hindustan Aeronautics Limited, Indian Space Research Organisation, Airbus, Boeing, General Electric (GE), Nokia, Toyota, and others, are housed here. Bangalore is known as India’s ‘Silicon Valley’, as it is home to many information technology (IT) enterprises. It is classified as a ‘non-attainment city’, meaning that pollution levels do not match the Central Pollution Control Board’s (CPCB) criteria. A high-level computer language called PYTHON was used to draw the trends of the air quality data collected over a 15-year period (2004-2019). PYTHON was used to clean, group, sort and aggregate the collected data to obtain the exceedance factor and draw the trend graphs. The policies of the Central Pollution Control Board (CPCB) and the Karnataka State Pollution Control Board (KSPCB) were examined to better understand the pattern. Over the years, the CPCB and the KSPCB have established a number of policies and guidelines, and the success or failure of these policies was examined in order to gain a better knowledge of the control measures. This report lays the groundwork for future policy implementation in other cities.

Abstract Urban noise pollution has become a pressing environmental concern, particularly due to its adverse effects on human well-being and quality of life. This study evaluates ambient noise levels in four key land-use zones—silence, residential, commercial, and transportation hubs within Central Nagpur. A total of 15 locations were systematically monitored across various times of the day (morning, afternoon, and evening) over a span of one week. The study involved computing essential acoustic indices such as Leq, Lmax, Lmin, L10, L50, L90, TNI, LNP, and Noise Climate (NC) to capture the noise characteristics comprehensively. The recorded values were assessed against the permissible limits set by the Central Pollution Control Board (CPCB). Results showed considerable exceedance in all zones, with the transportation and commercial areas reporting the highest average sound level, often exceeding 75 dB(A). Even designated silence zones, including hospital and educational areas, experienced noise levels beyond the CPCB threshold of 50 dB(A), indicating a serious breach of environmental standards. Time-based analysis revealed that noise levels peaked during typical traffic congestion hours in the morning and evening. This research highlights the widespread nature of noise pollution in urban Nagpur and emphasizes the need for tailored control strategies. These may include better traffic regulation, the use of sound barriers, stricter enforcement of noise norms, and enhanced public awareness. The outcomes offer crucial insights into sustainable urban management and future noise mitigation planning.

Abstract: Development activities like urbanization, transportation, industrialization and infrastructure development etc. has caused drawbacks to the environment. It has badly affected air quality. So, the problem statement of this project is “Development of modified wet scrubber to remove air pollutants at ambient condition.” A community was identified by using the Air Quality Data available on Central Pollution Control Boards website. It was found that Pune is the most polluted city in Maharashtra and Revenue Colony-Shivajinagar, Pune -IITM is the most polluted area of Pune city which we have identified using different sources. Data of concentration of air pollutants was presented on graph and compared with standard guidelines given by pollution control board. After comparing the data with the guidelines, we got to know that the concentrations of pollutants were beyond the limits set by the pollution control board. Then different alternatives were found to address this problem and from the available alternatives the best one which was chosen that was “Wet scrubber” which has the ability to remove gaseous pollutants as well as particulate matters. To improve the air quality, we designed a pollution cleaner tower which allow people to breathe and experience clean air for free. We implemented this project in the campus of Rajarambapu institute of technology, Rajaramnagar and got the good results with many advantages. And finally, from the tests conducted we concluded that the Pollution Cleaner Tower is able to trap pollutants effectively.

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.

Rivers are under increasing stress due to urbanization and other anthropogenic activities, leading to their over-exploitation and degradation. Godavari originates near Triambak in the Nasik district of Maharashtra, and flows through Madhya Pradesh, Karnataka, Orissa and Andhra Pradesh. Although its point of origin is just 80 km away from the Arabian Sea, it journeys 1465 km to fall into the Bay of Bengal. Like most other rivers, domestic pollution is the biggest polluter of the river Godavari, accounting for 82% of total pollution, whereas industrial pollution accounts for about 18%. The study covers 78 km of the river starting from the Kaigaon Toka to Shahagad. Six locations were selected for collection of water samples from the river and were analysed for water quality parameters in the environmental laboratory of Maharashtra Pollution Control Board (MPCB), Aurangabad. This data as well as the data from the Central Pollution Control Board were used to compute the National Sanitation, Foundation Water Quality Index (NSFWQI), which is generally applicable in USA and India. The results of the NSFWQI of Godavari River indicates its water quality as bad-medium over the stretch. Based on the results, the existing conservation measures have been reviewed and additional measures are suggested. The study concludes that major stress is industrial effluents and domestic pollution.

При всей значимости гидравлического портландцемента всемирная федерация Central Pollution Control Board относит карбонатную технологию к категории экологически вредных и опасных для окружающей среды. Обоснованием указанных доводов служат многие факторы, такие как крупно-масштабная добыча исчерпаемого природного ресурса, высокотемпературная обработка которого приводит к выбросам потенциально опасных для здоровья ультрадисперсной аспирационной и клинкерной пыли, углекислоты, сернистых соединений, тяжелых металлов, диоксинов и др. Снижение доли клинкера в составе вяжущего позволит создавать многокомпонентные цементные системы с использованием минеральных порошков, подвергнутых механо- или механохимической активации, что требует глубокого исследования их природы, условий формирования, обменной емкости и свойств в целом. Despite the importance of hydraulic Portland cement, the global federation Central Pollution Control Board classifies carbonate technology as environmentally harmful and hazardous to the environment. These arguments are substantiated by many factors, such as large-scale mining of an exhaustible natural resource, the high-temperature processing of which leads to emissions of potentially hazardous ultrafine aspiration and clinker dust, carbon dioxide, sulfur compounds, heavy metals, dioxins, etc. Reducing the proportion of clinker in the binder composition will make it possible to create multicomponent cement systems using mineral powders subjected to mechanical or mechanochemical activation, which requires a deep study of their nature, formation conditions, exchange capacity and properties in general.

This study undertakes a comprehensive spatio-temporal assessment of ambient air pollution in Firozabad over twelve years (2013–2024), focusing on key pollutants: particulate matter (PM₁₀), sulfur dioxide (SO₂), and nitrogen dioxide (NO₂). Utilizing data from three strategically located monitoring stations representing industrial (CDGI area), residential (Tilak Nagar), and commercial (Raja Ka Taal) zones, the research employs the Exceedance Factor (EF) methodology as prescribed by the Central Pollution Control Board (CPCB) to evaluate pollution levels against the National Ambient Air Quality Standards (NAAQS). The findings reveal persistently critical levels of PM₁₀ across all sites, with concentrations significantly surpassing the NAAQS limit of 60 µg/m³, particularly in residential areas where values peaked at 1100 µg/m³ in 2024. SO₂ levels remained within permissible limits throughout the study period, indicating effective control measures. However, NO₂ concentrations exhibited a concerning upward trend post-2020, approaching the NAAQS threshold, especially in residential zones, likely due to increased vehicular emissions and industrial activities. The study underscores the urgent need for targeted air quality management strategies, including adopting cleaner technologies, stringent emission controls, and enhanced public awareness to mitigate pollution levels and safeguard public health in Firozabad.

Due to urbanization and industrialization huge amount of wastewater is being generated, which is causing water pollution. Nowadays water pollution is a serious problem. The present study has been carried out to evaluate the efficiency of a waste water treatment plants with Extended Aeration Sludge Process (EASP). This has been done by examining the various physiochemical characteristics of wastewater (BOD, COD, TSS & PO4), including a comparison of these characteristics at inlet and outlets of wastewater treatment plants and their variance over time. The examination of the competency of a technology is necessary for further optimization of the treatment units whilst complying with the Central Pollution Control Board (CPCB) requirements. In New Delhi’s Extended Aeration Plants are not working to their peak potential, but have still been able to treat the significant wastewater effectively. The study implies that the effluent released into the Yamuna River would not contribute to the river’s level of pollution.

Abstract: This study presents a methodology for air pollution forecasting, aiming to improve accuracy through incorporating models for deep learning. Our goal is to create a reliable technique for forecasting air pollution concentrations. Central Pollution Control Board (CPCB) data undergoes exploratory data analysis. Analysis (EDA) and pre-processing before being split into training and testing sets. Two sequential models, Sequential-1 and Sequential-2, are compared, with Sequential-2 incorporating Conv1D layers alongside GRU for enhanced spatial-temporal modeling. Findings reveal that Sequential-2 consistently outperforms Sequential-1, exhibiting lower loss, mean squared error (MSE), validation loss, and validation MSE metrics. This indicates Sequential-2's superior predictive performance and generalization capability, attributed because of how well it can grasp spatial dependencies. In sum, the methodology proves that deep learning methods work well for predicting air pollution levels, offering promising avenues for accurately predicting pollutant concentrations and informing mitigation strategies for a healthier environment

The present study assessed the nationwide lockdown impacts on the air pollution situation across West Bengal, India. Air pollution data was collected from the online monitoring stations of the Central Pollution Control Board across West Bengal. The gradual declining pattern of overall pollution status was observed during the lockdown phase from the pre-lockdown phase. The early unlocking stage found slow and gradual increasing air pollution levels. Siliguri’s pre-lockdown ‘poor’ Air Quality Index (AQI) improved in the lockdown phase to ‘satisfactory’ level. ‘Moderate’ level AQI in Asansol of the pre-lockdown stage improved to ‘satisfactory’ level during the lockdown phase. Pre-lockdown AQI of both Kolkata and Howrah changed from ‘moderate’ to ‘good’ level during the lockdown phase. Unlike other pollutants, the ozone level increased in Kolkata, Howrah, and Siliguri in the lockdown phase. The early monsoonal washout possibly caused the changes in the pattern of pollution status of specified periods in the 2019 and 2020. Thus, in the study period of lockdown in 2020, the decrease in pollution level may not only caused by the stoppage of vehicles or industry but also have a possible natural influence.

Abstract Uncontaminated and fresh air is an elementary prerequisite of every living being. But, in this day and age, atmosphere contamination-is certainly the most pervasive kind of environmental-degradation. In the ambience, there are several pollutants which have widespread causing contamination in the air. Pollutants of chief concern include gaseous pollutants like carbon monoxide, ozone, oxides of sulphur and nitrogen, lead etc. These are primary pollutants. Secondary pollutants are particulate matters of different types ranging from fine to high. Every single one of these pollutants can cause a severe menace to human-health. In the current research, sensor-based equipments have been used to monitor and measure the concentration of various pollutants in the air. In the present research work, the effect of different pollutants like PM2.5, PM10, NO2 C02, TVOC, H-CHO, Temperature, Humidity and Noise on air pollution at five stations in the education institute namely RCOEM campus is studied and presented. It had been observed that air pollutants like PM2.5, PM10, and NO2 primarily affected the air quality of RCOEM campus. So, these pollutants are mainly considered to monitor and evaluate air quality of RCOEM campus. After evaluation, air quality index of RCOEM campus was found to be around 94.5. It is within the range of 51-100. So, its falls in the range of satisfactory as per standard norms of central pollution control board and state pollution control board in terms of quality of the air and thereby its contamination.

Full textAbstract:
Presently, air pollution remains a significant environmental threat across the world. However, variation of air pollutants is largely associated with the changes in season (pre-monsoon, monsoon, post-monsoon, and winter), climatic conditions, and certain anthropogenic activities. Recently, a significant drop in the levels of air pollutants was observed due to COVID-19 lockdown in various parts of the world. Therefore, this study was performed to assess the impact of COVID-19 restrictions (pre-lockdown and post-lockdown) on the air quality of Uttarakhand state, India. Purposively, the air quality data from 8 stations collected by the Uttarakhand pollution control board was analyzed. The findings exhibited that there was a significant variation in average concentration of air pollutants including, PM10, PM2.5, SO2, and NO2. However, particulate matters were amongst the top contributors towards ambient air pollution while the gaseous pollutants such as SO2 and NO2 are below the standards given by the Central Pollution Control Board (CPCB). The present study confirmed that during the initial lockdown in 2020, the concentration of SO2, NO2, PM2.5, and PM10 decreased significantly by 9.46-86.4%, 20-74.6%, 35.6-62.6%, and 14.7-65% respectively as compared to the previous year (2019) while a significant corresponding increase by -11.6-96.5%, -9.5-70.6%, 5.1-57.6% and -17.06-71.7% was observed, respectively in comparison to the succeeding year (2021). Moreover, a considerable variation of air pollutants in different seasons and dramatic improvement in the air quality index (AQI) were observed during the lockdown period. The findings of this work suggested that the decrease in outdoor human activities can contribute significant improvement in the ambient air quality of the state of Uttarakhand, India.

Land zonings process like what achieved in this paper will help and of it’s of a high interest point for the future of Kirkuk city especially urban planning and economic issues of the city. Also, it may be considered as a reference in solving the traffic jam problems in the city. Transportations and sounds of horn of vehicles are the major sources of traffic noise pollutions .Vehicular traffic noise problems are contributed by various types of vehicles such as heavy and medium trucks or buses or automobiles. During this study, six major regions within the city were selected (Governorate region, Baghdad road, Al Wasti, Al Askary, Al Nasir and North garage). A survey for all those six regions were taken place and noise measurements were captured at points or near to the intersections for a duration of three different periods days per a week [ Sunday 3rd , Monday 4th , and Tuesday 5th] of January 2016. The results showed a high level of noise pollution and super passing on many occasions to the prescribed levels by Central Pollution Control Board (CPCB) , maximum level noise pollution value was 94.6 dB(A) in AlWasti region near to the road that leading to Kirkuk university , while minimum level noise pollution value was 48 dB(A) in AlNasir region. As a result, a noise map zoning was prepared for Kirkuk City for top peak working three days. The prepared noise distribution map will help and could be used as a considerable point for the future during designing projects related to transportations. Also in another hand, the map reflected indirectly the amount of regional air pollutions. High distributed noise pollution zones means a zone of a high air pollutions levels specially Cox and Nox gaseous pollutions.

Air pollution constitutes the most significant issue affecting India. A multitude of individuals are experiencing various ailments as a direct consequence of air pollution. The Air Quality Index (AQI) is employed as a means to report the state of air pollution, providing a daily assessment of air quality. The examination of air quality serves the purpose of assessing the atmospheric condition in a given location. To facilitate this, the Central Pollution Control Board (CPCB) has established monitoring centers in two areas within the Sonbhadra district, namely Annpara colony and Renusagar colony. A comprehensive investigation spanning six years (2017-2022) has been conducted for the Sonbhadra district, examining the annual and seasonal fluctuations in the Air Quality Index. The data utilized for this analysis was obtained from CPCB and enabled the calculation of annual figures by determining the average mean. Moreover, the pollution situation in the city was evaluated using the exceedance factor (EF). The examination of these figures reveals that the city exhibits a higher concentration of PM 10 pollutants. Conversely, the levels of NO2 and SO2 are relatively well-regulated. Notably, the year 2018 was marked by the highest levels of pollution, while 2020 witnessed the lowest pollution levels. These findings suggest that the pollution prevention measures implemented in the city over the years have been effective.

River water quality is an important issue as rivers are one of the major sources of fresh water for drinking, agriculture, residential use, hydroelectric power plant, tourism, transportation, and others. In spite of abundance of surface water in Brahmaputra basin, only 47% rural population of Assam has access to potable water. It is important to check water quality at regular intervals and prevent and control their pollution. An attempt was made to study water quality of rivers of the Brahmaputra basin in Assam focusing designated best use concept. Water quality status was evaluated from analysis of water samples and secondary data from reports of Central Water Commission and Pollution Control Board, Assam. It is found that water of most of the rivers fall under ‘B’ and ‘C’ class (as per designated best use concept, class ‘B’ water can be used for bathing and class ‘C’ water can be used as drinking water source with conventional treatment followed by disinfection). Most of the rivers of the Brahmaputra basin have moderate or low pollution, mainly due to rejuvenated life every year during monsoon. However, with contemporary issues of population explosion, increasing demand for water, flood, growing pollution and climate change, it is imperative to take precautionary approach to the pristine as well as ecologically challenged rivers of Brahmaputra basin in India.

Urbanization and Industrialization during the last few decades have increased air pollution causing harm to human health. Air pollution in metro cities turns out to be a serious environmental problem, especially in developing countries like India. The major environmental challenge is, to predict accurate air quality from pollutants. Envisaging air quality from pollutants like PM2.5, using the latest deep learning technique (LSTM timer series) has turned out to be a significant research area. The primary goal of this research paper is to forecast near-time pollution using the LSTM time series multivariate regression technique. The air quality data from Central Pollution Control Board over Hyderabad station has been used for the present study. All the processing is done in real-time and the system is found to be functionally very stable and works under all conditions. The Root Mean Square Error (RMSE) and R2 have been used as evaluation criteria for this regression technique. Further, the time series regression has been used to find the best fit model in terms of processing time to get the lowest error rate. The statistical model based on machine learning established a relevant prediction of PM2.5 concentrations from meteorological data.

The water quality of seafronts and beaches of Mumbai is under pressure and deteriorating due to discharge of partially treated sewage and wastewater through point and nonpoint sources. The objective of the study was to assess the water quality and to correlate physico-chemical and bacteriological parameters for establishing relationship, association and dependence on each other. The water quality parameters were selected as per SW II standards specified by Central Pollution Control Board, India and nutrient parameters as strong indicators of sewage pollution. Box and whisker plots were generated for evaluating spatio temporal variation of water quality which suggest influence of organic pollution mostly at Mahim and Dadar in the form of outliers and extremes. Pearson's correlations were estimated between parameters and found significant correlation with each other indicating influence of sewage on water quality. The water quality of beaches and seafronts were found unsafe for recreational purposes. The study suggested that designated water quality can be achieved by restricting nonpoint source through improvement in wastewater collection systems, appropriate level of treatment and proper disposal.

The environment we live in is very fragile and has a delicate balance. In the current era, the human kind is consuming the natural resources at a higher rate than it can produce it and is generating wastes at a higher rate than the environment can remove it. Because of anthropocentric ideology, human race believes in development through destruction. The urge for luxury and sophistication has given an impetus to industrial revolution and technological development. This has lead to exponential consumption of resources of the world. To worsen this scenario, the world has undergone huge population explosion in the 19th century. This has increased pressure on all available resources. Hence, in order to meet the current demands, people started using unsustainable technologies leading to huge pollution in all sectors. In this paper, the adverse effect of population growth in India on various factors like water pollution, emissions of CO2 and green house gases are discussed. The data for analysis are based on the statistics of United Nations Population Division, The WorldBank data bank and Central Pollution Control Board of India.

The Bharalu river, flowing through the Guwahati city is notoriously known for its critically polluted water quality as reported by the Central Pollution Control Board. Although the river is highly polluted, still a few organisms including microbes, such as algae are found to thrive in it. The purpose of the present research is to study and identify the pollution tolerant algal species present in the polluted water of Bharalu river, so that their bioremediation potential can be explored subsequently. During the study, altogether 33 species of phytoplankton distributed in four different families were recorded. Chlorophyceae has been represented by 20 species followed by Bacillariophyceae, Cyanophyceae and Euglenaceae with 8, 3 and 2 species, respectively. Scenedesmus was the most dominant genera with a total of 11 species. Phytoplankton peaks were observed during Jan- Feb (19×103 units/l).

Full textAbstract:
Biomedical waste management is one of the emerging causes for Hospital Acquired Infection, which is very important to deal with due to its significant impact on the health and environment. Biomedical waste generated in dental clinics and hospitals if not managed properly, can create various health hazards to dental professionals, dental auxiliaries, patients and other dental health care service providers who work in dental office. Each dental health care provider should have knowledge about handling and disposal of biomedical waste. In this article different methods of handling and disposal of biomedical waste during the unprecedented times of COVID-19 are elaborated. Revised guidelines are provided by central pollution control board (Govt of India), American dental association, Centre for disease control, world health organization and other organizations dealing with waste management are discussed in this article.

Full textAbstract:
Poor air quality in India has sparked our interest in studying the time series dynamics of PM2.5 in India’s five most populous cities (Mumbai, New Delhi, Hyderabad, Chennai, and Kolkata). Daily data for the period 2014–2023 are examined in the paper. Using fractional integration methods, we analyze the persistence, seasonality, and time trends of the data. The results indicate that all seriGewekees display fractional degrees of integration, being smaller than 1 and thus presenting mean reversion. Moreover, the time trends are significantly negative only for New Delhi and Kolkata, implying a continuous reduction in the level of pollution. These findings suggest that targeted interventions, such as stricter emission regulations, improved urban planning, and the promotion of clean technologies, are essential to sustain and amplify the observed improvements in air quality. The study also highlights the need for consistent and long-term efforts to address pollution in Mumbai, Hyderabad, and Chennai, where no significant reductions have been observed, emphasizing the importance of adapting policies to regional conditions. The paper’s findings can serve as a guide for air pollution management and for policymakers at the Central Pollution Control Board (CPCB), the governmental body responsible for monitoring and regulating environmental pollution in India.
