BACKGROUND Air pollution contributes significantly to global increases in mortality, particularly within urban environments. Limited knowledge exists on the mechanisms underlying health effects resulting from exposure to pollutant mixtures similar to those occurring in ambient air. In order to clarify the mechanisms underlying exposure effects, toxicogenomic analyses are used to evaluate genome...
What is air quality? Zhang (2005) defines air quality as the degree of pollution of clean air. Clean air is the air that is free from impurities. Air quality can be determined by measuring the concentration of pollutants in the air. The lower the concentration of airborne pollutants, the better is the air quality. Auvermann (2006) defined air pollutants as compounds or materials that, when susp...
Some of the highest exposures to air pollutants in developing countries occur inside homes where solid biofuel, particularly wood fuel, is used for daily cooking. A relatively high proportion of the world population living in these countries is exposed to increased levels of indoor air pollutants produced by inefficiently burning stoves. Inhalation of these pollutants may have serious consequen...

I Data from large incinerators shows the potential release of dioxins, heavy metals, and acid gases as air pollutants. Hospital incinerators can present similar problems to a much greater degree, especially ,sinc-e,most of these smaller incinerators do not have effective c'ijmbustion or emission controls and their emissions are poorly dispersed. high content of plastics in the waste. potential ...
Incineration is a widely used and well established technology for the municipal solid waste (MSW) management. Modern MSW incineration plants are equipped with improved air pollution control (APC) systems, which reduce pollutants well below the established limits. The environmental concern has, thus, moved from the air emissions to the solid residues generated from the APC systems of the inciner...
Abstract We conducted ambient monitoring of various hazardous air pollutants (HAPs) for 2 years (2013-2015) in two adjacent Korean cities a megacity area: Seoul and Incheon. Measured HAPs included volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), heavy metals (HMs). The objectives this study were to evaluate the spatiotemporal variations HAPs, prioritize based on healt...
