The present study is a screening analysis to investigate the pollution loads in ur...

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...

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...
