BACKGROUND: Numerous earlier studies examining the association of air pollution with maternal and foetal health estimated maternal exposure to air pollutants based on the women's residential addresses. However, residential addresses, which are personally identifiable information, are not always obtainable. Since a majority of pregnant women reside near their delivery hospitals, the concentrations of air pollutants at the respective delivery hospitals may be surrogate markers of pollutant exposure at home...

Air pollution is a significant environmental and health hazard. Earlier studies had examined the adverse health effects associated with short- and long-term exposure to particulate matter on respiratory disease. However, later studies demonstrated that was actually cardiovascular disease that accounted for majority of mortality. Furthermore, it was not gaseous pollutants like oxides of nitrate, sulfur, carbon mono-oxide or ozone but the particulate matter or PM, of fine or coarse size (PM2.5 and PM10) which was linearly associated with mortality; PM2...

Air pollution is composed of particulate matter (PM) and gaseous pollutants, such as nitrogen dioxide and ozone. PM is classified according to size into coarse particles (PM10), fine particles (PM2.5) and ultrafine particles. We aim to provide an original review of the scientific evidence from epidemiological and experimental studies examining the cardiovascular effects of outdoor air pollution. Pooled epidemiological studies reported that a 10μg/m(3) increase in long-term exposure to PM2.5 was associated with an 11% increase in cardiovascular mortality...

BACKGROUND: Numerous studies show associations between exposure to Particulate Matter and Cardiovascular disease (CVD). Current cardiovascular equations incorporate the major risk factors for CVD. The patients' environment, however, is not incorporated in these equations. METHODS: In a retrospective analysis, we assessed the contribution of neighborhood greenness and particulate matter (coarse-PM and PM<2.5μm-PM2.5) to the development of CVD by analyzing the change in prediction abilities...

Exposure to ambient particulate matter (PM) links with a variety of respiratory diseases. However, compared with coarse particles (PM10) and fine particles (PM2.5), submicrometer particles (PM1.0) may be a more important indicator of human health risks. In this study, the cytotoxic and genotoxic effects of PM1.0 samples from Shanghai were examined using A549 cells, and compared with the effects of PM2.5, to better understand the health effects of PM1.0 in this area. The PM1.0 and PM2.5 samples were characterized for morphology, water-soluble inorganic ions, organic and elemental carbon, and metal elements...
