introduction: a major concern of human being is accumulation and toxicity of heavy metals in their body. copper is a heavy metal ion that in concentration of 2 mg/l can cause numerous complications. different treatment methods have been proposed for removing metals from contaminated water by researchers. among these methods, sorption seems a better method with high removal efficiency. in this s...

Industrial pollution was endemic to the industrial cities of the 19th century and remains a feature of some modern cities, particularly industrial cities in emerging economies. This study compares the relationship between pollution and mortality in both the historical and modern context, focusing on English cities in the mid-19th century and Chinese cities in 2000. For both contexts, we constru...

Urban air pollution is one of the major environmental problems faced by the developing countries. Studies in large Indian cities revealed that ambient air pollution concentrations are at such levels where it can cause serious health impacts. Lucknow, a fast growing city is not an exception to this. Researchers from the city have studied various aspects of air pollution during the last one and h...

Environmental economics has made numerous contributions to both the theory and the applied problems surrounding pollution control. Given that the primary benefits of controlling most pollutants are health benefits, there is a close link between human health and environmental economics. One of the most important contributions that economics has made to the problem of pollution control is to clar...

The health effects of air pollution include increases in Air pollution on Pdient visits in &be 1 severity and incidence of asthma. exacerbation of COPD. increase California faces both increasing air temperatures as well as air pollution. This conclusion is being drawn by many non-scientists who simply observe daily atmospheric conditions: more hot days exist in many areas of California and many...

Background Air pollution is of particular concern in India, which contains 11 of the 20 most polluted cities in the world. Media coverage of air pollution issues plays an important role in influencing public opinion and increasing citizen demand for action on clean air policy. Hence, this study was designed to assess news coverage of air pollution in India and its implications for policy advanc...

BACKGROUND Emerging evidence suggests that near-roadway air pollution (NRP) exposure causes childhood asthma. The associated costs are not well documented. OBJECTIVE We estimated the cost of childhood asthma attributable to residential NRP exposure and regional ozone (O3) and nitrogen dioxide (NO2) levels in Los Angeles County. We developed a novel approach to apportion the costs between thes...

Daily and seasonal fluctuations in mortality have been positively and significantly associated with ambient concentrations of atmospheric pollution and meteorological variables such as temperature and barometric pressure. However, much less is known about the health risk from atmospheric pollutants in the context of frequently occurring weather patterns. The objective of this study is to assess...

BACKGROUND Exposure to air pollution is frequently associated with reductions in birth weight but results of available studies vary widely, possibly in part because of differences in air pollution metrics. Further insight is needed to identify the air pollution metrics most strongly and consistently associated with birth weight. METHODS We used a hospital-based obstetric database of more than...

This project was conducted by the Pollution Prevention Research Branch(PPRB) of the U.S. Environmental Protection Agency(EPA) with the cooperation of Union Carbide Corporation, Nordson Corporation , and the Pennsylvania House Furniture Company. The PPRB is evaluating and demonstrating new technologies for pollution prevention through the Pollution Prevention Clean Technology Demonstration (CTD)...
