This paper finds that a 10-μg/m3 increase in airborne particulate matter [particulate matter smaller than 10 μm (PM10)] reduces life expectancy by 0.64 years (95% confidence interval = 0.21-1.07). This estimate is derived from quasiexperimental variation in PM10 generated by China's Huai River Policy, which provides free or heavily subsidized coal for indoor heating during the winter to cities ...

The health implications of atmospheric particulate matter have become a topic of much interest on both sides of the Atlantic, but especially in the USA, where they were at the centre of the debate over the Environmental Protection Agency's (EPA) revision of the National Ambient Air Quality Standard in 1997. Much of this debate revolves around claims that particulate matter (usually represented ...

This study aimed to estimate the associations between air pollution and esophageal cancer. In the ecologic cross-sectional study, correlation analyses were made between city-level mean concentrations of particulate matter less than 10μm in aerodynamic diameter (PM10), SO2, NO2 and city-level age-standardized mortality rates of esophageal cancer in Shandong Province, China. PM10 (p=0.046) and NO...

BACKGROUND The aerodynamic diameter of biological particles determines their ability to penetrate the human respiratory system. OBJECTIVE To assess the content of allergens less than 10 pm in diameter in the particle fraction of airborne dust in order to improve control of exposure to harmful soybean aeroallergens. METHODS In this study, 98 pairs of particulate matter measuring less than 10...

PM10 concentrations were measured at Nellis Dunes Recreation Area (NDRA), Nevada, USA. NDRA is a desert area located 6 km northeast of the metropolitan area of Las Vegas. Three sources contribute to the dust at the site: local wind erosion, off-road vehicular activity and dust production in the city of Las Vegas. PM10 concentrations were measured during one complete year and stored as 20-min av...

Air pollution is now a significant environmental issue in China. To better understand the health impacts of ambient air pollution, this study investigated the potential interaction between PM10 and NO₂ on mortality in Guangzhou, China. Time series data of daily non-accidental mortality and concentrations of PM10 and NO₂ from 2006 to 2010 were collected. Based on generalized additive model, we d...

BACKGROUND Particulate matter and proximity to large roadways may promote disease mechanisms, including systemic inflammation, hormonal alteration, and vascular proliferation, that may contribute to the development and severity of endometriosis. OBJECTIVE Our goal was to determine the association of air pollution exposures during adulthood, including distance to road, particulate matter<2.5 μ...

Based on emission factors derived from the AP-42 algorithm, particulate matter from paved roads has been estimated to be a major source of PM10 of geologic origin. This is an empirical formula based on upwind-downwind measurement of PM10 concentrations and is dependent solely on the silt loading of the pavement and the weight of vehicles. A number of upwind-downwind studies conducted in urban a...

OBJECTIVES To determine the presence and magnitude of any relation between short term variations in ambient concentrations of particulate matter under 10 microns in diameter (PM10) and hospital admissions and mortality in Birmingham, United Kingdom. To find the relative risk associated with various concentrations of PM10, and to estimate the potential public health benefit of reducing PM10 to b...
