Abstract:

La pollution de l'air demeure l'un des principaux fléaux des temps modernes. Outre la pollution atmosphérique dite « primaire » se développe aussi une pollution atmosphérique plus pernicieuse, appellée « secondaire », produite dans l'environnement atmosphérique. Elle est le fruit d'une chimie atmosphérique multiphasique, impliquant des composés organiques et radicalaires, rendue complexe à la fois par le grand nombre de composants de l'air et par la multiplicité de leurs voies d'évolution chimique. En mettant en perspective cette complexité, cet article se propose de donner quelques clefs pour

Abstract:

Background: Hypertension is a significant public health problem in low- and middle-income countries (LMICs). This study aimed to examine the association between household air pollution (HAP) and blood pressure using data from the 2016 Albania Demographic Health and Survey (DHS). Methods: We computed the odds ratio (OR) for the prevalence of hypertension between respondents exposed to clean fuels (e.g., electricity, liquid petroleum gas, natural gas, and biogas) and respondents exposed to polluting fuel (e.g., kerosene, coal/lignite, charcoal, wood, straw/shrubs/grass, and animal dung).

Abstract:

When biomaterials are used as adsorbents, some compounds present in their structure can be extracted and cause secondary pollution of the treated water. Depending on the type and amount of the secondary pollution, some materials can be unacceptable as adsorbents despite of their good adsorption capacity. Although, it is not a newly discovered phenomenon and it is recognized as a problem, leaching from adsorbents is neglected. The aim of our study is to investigate the secondary pollution of the water during the biosorption of heavy metal ions by pristine and modified sugar beet shreds from bio

Due to the development of industrialization and urbanization, secondary pollution is becoming increasingly serious in the Yangtze River Delta. Volatile organic compounds (VOCs) are key precursors of the near-surface ozone, secondary organic aerosol (SOA), and other secondary pollutants.

Abstract:

Small spacing tunnel due to the special structure form and two tubes are only separated by a thin wall. This structure form is likely to cause secondary pollution, pollution gas discharged into the adjacent tunnel. This phenomenon will lead to increased ventilation system energy consumption. This paper analysis gas diffusion path between two adjacent tunnels, using CFD (Ansys Fluent). To relieve the pollution gases secondary pollution of tunnel portal area, using CFD analyzed gas diffusion path under different circumstances, for opening hole on the top of sunshades, extended of the wall betwee

Abstract:

Increasing public interest and more anti-pollution legislation sharpen the need to avoid pollution. Soil, water and air are at risk.Apart from plant nutrient considerations, secondary effects of water-logging and oxygen depletion of the soil can occur. Slurry tankers can cause damage to the field surface by rutting. Some tankers exert pressures of 70 psi on the soil and then are often used on wet soils. Such malpractices create extra costs to rectify extra problems created.

Abstract:

Environmental factors significantly influence students' academic performance, with hazardous conditions posing notable impediments to educational outcomes. This study investigated the impact of environmental hazards—air pollution, noise pollution, and flooding—on the academic performance of students in public secondary schools in the South-South region of Nigeria. Three objectives and corresponding hypotheses guided the research. Employing a correlational survey design, the study targeted all principals of public secondary schools in the region. A purposive sampling technique was used to selec

Abstract:

Abstract Air pollutions are shown to increase the occurrence of cardiovascular diseases and ischemic stroke. These effects imply an indirect exposure of secondary organs downstream of the respiratory system as the primary target of exposure. Mechanistic studies of air pollution on secondary organs have traditionally been performed on organ specific monocultures at submerged conditions. Direct exposure to organ specific cells secondary exposed to air pollution have the drawback that it does not imply realistic exposure conditions. In this study we have indirectly exposed organ specific cells to

Abstract:

For a winter pollution episode in Yinchuan, a city in Northwestern China, ambient aerosols were characterized using a real-time single-particle aerosol mass spectrometer (SPAMS). More than 160,000 individual particles analyzed with the SPAMS were classified into eight major categories on the basis of their mass spectral patterns: traffic emissions, biomass burning, dust, coal burning, industrial emissions, secondary inorganic, cooking, and others, all of which contribute to fine particles. The results revealed that coal burning (29.6%) and traffic emissions (23.4%) were the main sources during

Abstract:

Despite the decline in partially (PM<sub>10</sub>) and fully (PM<sub>2.5</sub>) inhalable particles observed in recent decades, Santiago in Chile shows high levels of particle and ozone pollution. Attainment plans have emphasized measures aimed at curbing primary and, to some extent, secondary particles, but little attention has been paid to photochemical pollution. Nevertheless, ozone hourly mixing ratios in Eastern Santiago regularly exceed 110 ppbv in summer, and in winter maximum mixing ratios often reach 90 ppbv. Moreover, the sum of ozone and nitrogen dioxid

Abstract:

A novel material, zero valent iron composited organobentonite (NZVI-OB), was synthesized to adsorb dye from wastewater and to degrade the dye for avoiding secondary pollution. The crystal structure was characterized with X-ray diffraction (XRD). The effect of initial Orange II concentration and reaction time on the removal of Orange II by the NZVI-OB was studied. And the removal mechanism of Orange II was discussed. The results show that the Orange II can be removed by NZVI-OB efficiently. The maximal adsorption amount is 112.66 mg/g. The iron can effectively degrade the organic compounds afte

AbstractHaze in Beijing is linked to atmospherically formed secondary organic aerosol, which has been shown to be particularly harmful to human health. However, the sources and formation pathways of these secondary aerosols remain largely unknown, hindering effective pollution mitigation. Here we have quantified the sources of organic aerosol via direct near-molecular observations in central Beijing. In winter, organic aerosol pollution arises mainly from fresh solid-fuel emissions and secondary organic aerosols originating from both solid-fuel combustion and aqueous processes, probably involv
