background : health professionals face the adverse health effects of climate change and air pollution in their practices. this review underscores the effects of these environmental factors on maternal and children’s health, as the most vulnerable groups to climate change and air pollution. methods : we reviewed electronic databases for a search of the literature to find relevant studies publish...
pollution control is based on correctly measuring pollutant concentrations but, at the moment,the principal european cities only monitor pollution levels by means of a few fixed stations co-located inselected points of the urban layout far from hotspots and/or by means of meteorological prediction models offuture pollution. few cities integrate the information from both sources. the implementat...

Abstract Modern coral reefs face substantial threats that endanger their capacity to function and provide resources for human populations. Chronic pressure through exploitation land-based pollution has led reef degradation lower productivity.

This study explores the differences in pollution control performance of industries with different types of ownership – State owned (SOE), collectively or community owned (COE), and privately owned (POE). A theoretic analysis is conducted and followed by an empirical assessment with Chinese data. The empirical results show that the COEs in China have better environmental performances in water po...
