Rapid urbanization and economic development inevitably lead to light pollution, which has become a universal environmental issue. In order to reveal the spatiotemporal patterns and evolvement rules of light pollution in China, images from 1992 to 2012 were selected from the Defense Meteorological Satellite Program Operational Linescan System (DMSP/OLS) and systematically corrected to ensure con...

This paper looks at three contaminated communities in southern Europe facing pollution from industrial and mining activity analyses forms of avoidance behaviour, using both economic sociological approaches. Based on a quantitative household survey, we show that behaviour is mainly explained by residential location socio-economic characteristics. Pollution perception not statistically correlated...

Increasing concerns about climate change have given rise to the formation of International Environmental Agreements (IEAs) as a possible solution to limit global pollution effects. In this paper, we study the stability of IEAs in a repeated game framework where we restrict to strategies which are simple and invariant to renegotiation. Our main contribution to the literature on IEAs is that we a...

one of the important factors influencing outdoor insulators performance is pollution phenomenon. the pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of leakage currents (lc) on the insulator surface, which may result in total flashover. the lc characteristics are affected by parameters such as nature and severity of pollution. loca...

CONTEXT Previous studies have suggested that excessive lead exposure is related to aggressive and violent behavior. OBJECTIVE To evaluate the association between estimated air lead concentrations and homicide rates. DESIGN Cross-sectional ecological study. SETTING All counties in the contiguous 48 states of the United States. EXPOSURE MEASURE: Estimated air lead concentrations and blood l...

The aim of this study is to model downward migration of lead from the plow layer of an experimental site located in Versailles (about 15 km southwest of Paris, France). Since 1928, samples have been collected annually from the topsoil of three control plots maintained in bare fallow. Thirty samples from 10 different years were analyzed for their lead and scandium contents and lead isotopic comp...
