Daily PM2.5 mass concentrations and chemical compositions together with the aerosol optical properties were measured from 8–28 November 2011 in Beijing. PM2.5 mass concentration varied from 15.6–237.5 μg·m−3 and showed a mean value of 111.2 ± 73.4 μg·m−3. Organic matter, NH4NO3 and (NH4)2SO4 were the major constituents of PM2.5, accounting for 39.4%, 15.4%, and 14.9% of the total mass, respecti...

OBJECTIVES A growing number of epidemiological studies are showing that ambient exposure to particulate matter air pollution is a risk factor for cardiovascular disease; however, whether occupational exposure increases this risk is not clear. The aim of the present study was to examine whether occupational exposure to particulate air pollution increases the risk for ischaemic heart disease and ...

Water quality assessment at the watershed scale requires not only an investigation of water pollution and the recognition of main pollution factors, but also the identification of polluted risky regions resulted in polluted surrounding river sections. To realize this objective, we collected water samplings from 67 sampling sites in the Honghe River watershed of China with Grid GIS method to ana...

the present study aims to analyze the existing indoor environmental conditions of firozabad city along with its impact on people’s health by going through the correlative index of indoor environment’s determinant and different diseases, faced by the people. in order to measure spatial disparities, the statistical technique, i.e. the standard score additive model (z- score), has been applied to ...

this study proposes a method employing thermogravimetric analysis (tg) to predict pollutionlevels by heavy metals (cr, cu, ni, zn, pb, cd and hg) in port sediments close to urban and industrial sitesfrom bay of cádiz. for this purpose, the thermogravimetric results of 14 sediment samples were recorded andshowed two characteristic ranges of temperatures (w1 as weight loss, %: 200-650°c) vs. (w2 ...

Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), dioxins and furans are persistent organic pollutants with well-known toxicity and carcinogenic activity. These organic pollutants have the tendency to bioaccumulate, present little or no biodegradation and subsequently, could cause a menace to the ecosystems and human health. This review discusses the occurrence, fate an...

background : studies have shown that noise pollution has harmful effects on human health. the sound of traffic is the main source of noise pollution in cities. the purpose of this study was to determine noise pollution using a geographical information system (gis) in the main streets of kashan, iran. methods: in this study, 180 noise samples were collected from 20 regions of the main streets in...

All thes...

Water of River Kosi in stretch of 35 Kms at Rampur was studied for pollution by determining various water quality parameters, for all three seasons viz. winter, summer and rainy season. The river is subjected to severe domestic and industrial pollution at Kashipur (U.A). This polluted water is carried down stream to Rampur (U.P.). The pH range is 7.3 to 7.9.The organic pollution is mild as indi...
