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...
While more attention has been paid in recent years to urban point source pollution control through the establishment of wastewater treatment plants in many developing countries, no considerable planning nor any serious measures have been taken to control urban non-point source pollution (urban stormwater runoff). The present study is a screening analysis to investigate the pollution loads in ur...
amir kabir dam was built in varian strait, at 23 km north of karaj in 1961. the dam is multipurpose and its maim aims are the spring floods control, supplying potable water for tehran city, producing electricity and providing irrigation water. different pollutants which discharge to the river finally enter to the dam reservoir. determining the pollution loads of the dam sub-catchments can help ...
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...
Due to economic benefits, pollution control costs and the compensated side’s strategy to get more compensation, many eco-compensation projects can not achieve desired outcome. In this paper, we assume that the pollution control strength of the compensated side is private information and establish a two-stage dynamic game model with incomplete information to analyze the strategy of the two sides...
Pollution: Associations Persist with Continued Advances in Research Methodology (See Neas et al., p. 629; Lee and Schwartz; p. 633; and Fairley, p. 637) In this issue of Environmental Health Perspectives there are papers by Fairley, Neas et al., and Lee and Schwartz. Although these papers present different approaches, they provide a reasonable representation of stateof-the-art epidemiologic res...
Globally, almost 3 billion people rely on biomass (wood, charcoal, crop residues, and dung) and coal as their primary source of domestic energy. Exposure to indoor air pollution (IAP) from the combustion of solid fuels is an important cause of morbidity and mortality in developing countries. In this paper, we review the current knowledge on the relationship between IAP exposure and disease and ...
the most important environmental pollutant in steel industry is air pollution due to the process of its products. optimise sitting for this industry, in a great extend will prevent pollutants and emissions. khorasan steel company is located near some populous villages and three rivers. it is necessary to perform an investigation for providing abatement and control of air pollution, in time of p...
Scientific efforts to understand the health effects of air pollution and public policy efforts to control air pollution have a fascinating history. The early “killer smog” episodes in Meuse Valley, Belgium (1930), Donora, Pa (1948), and London, UK (1952) provided stark evidence of deleterious respiratory and cardiovascular health effects of severe air pollution exposure. This evidence motivated...
