2,3. Assessments of the chronic and acute effects of particulate matter on human health tend to be based on mass concentration, with particle size and composition also thought to play a part4. Oxidative potential has been suggested to be one of the ...
Studies have shown that nutritional supplements could reduce the adverse effects induced by air pollution. However, whether dietary patterns can modify the association of long-term exposure to fine particulate matter (PM2.5) and its constituents with hyp
Because of the nature of self-comparison, this design has the advantage of adjusting for potential confounding by factors that remain constant over a short period of time, such as individual-level socio-demographic characteristics, day of the week, and seasonal patterns.17 Exposure assessment Daily...
the size distribution of particulate pollutants is very important in understanding the transport and removal of particles in the atmosphere and theirdeposition behaviorin the human respiratory system. Their chemical composition may determine the type of effects caused by particulate matter on humans, veget...

Air pollution and particulate matter (PM) are significant factors for adverse health effects most prominently cardiovascular disease (CVD). PM is produced from various sources, which include both natural and anthropogenic. It is composed of biological components, organic compounds, minerals, and metals...
