BACKGROUND Meteorological conditions and air pollution in urban environments have been associated with general population and elderly mortality, showing seasonal variation. OBJECTIVES This study is designed to evaluate the relationship between apparent temperature (AT) and air pollution (PM₂.₅) vs. mortality in elderly population of Metro Vancouver. METHODS Statistical analyses are performe...
Air pollution causes severe physical and psychological health complications. Considering China's continuously-deteriorating air quality, this study aimed to assess the self-reported effects of air pollution on the behavior and physical health of the students of 13 densely populated cities, and their awareness, practices, and perception of air pollution and its associated public health risks. A ...
Air pollution is one of the leading causes of lung cancer. Air pollution-related lung cancer is a deteriorating public health problem, particularly in developing countries. The MUC16 gene is one of the most frequently mutated genes in air pollution-related lung cancer. In the present study, MUC16 mRNA expression was increased in ∼50% of air pollution-related lung cancer samples obtained from pa...

In most countries, environmental regulation has focused on local pollution, which causes damages near the emission source, while national regulation on greenhouse gases (GHG) has been slow. In this paper, we ask whether US local air pollution regulations have had an effect on GHG emissions. On the one hand, a firm required to lower emissions of local pollutants might respond by adopting technol...
Carbon dioxide causes green house effect and has been considered as a pollutant source forsafe environment. Since combustion of fossil fuel may create tremendous amount of carbon dioxide,detecting any pollutant sources would be important to eliminate the origin of pollution sources.Evaluation of smoke dispersion generated by the power plant utilizing fossil fuel is the objective of thispaper. T...
in this research, the effect of air pollution on proline concentration, soluble sugar, anatomical and morphological features was studied in two plant species malva parviflora and hordeum glaucum in 2009. the area of the stand steel factory of khuzestan was considered as the polluted site and shush region was considered as the control site, and sampling was carried out from the two sites, accide...

Background. Environmental pollution has become the leading risk factor for death in low- and middle-income countries (LMICs). The World Health Organization and others calculate that exposures to polluted air - indoor and outdoor, water and soil resulted in 8.4 million deaths in LMICs in 2012. By comparison, HIV/AIDS causes 1.5 million deaths per year, and malaria and tuberculosis Less than 1 mi...
