Analysis of Health Effects Resulting from Population Exposures to Ambient Particulate Matter. Health and Environmental Effects Document, 1985

摘要

Findings from our recent epidemiologic analyses reported here indicate that variations in ambient fine particle mass (d/sub a/ < 2.5 mu m toxic substances include arsenic, cadmium, sulfur, and carbonaceous compounds). SO sub 4 /sup =/ mass are more important to public health than variations in the levels of particle mass measures which also include coarse particles (d/sub a/ > 2.5 mu m). Sulfates and FP mass were often very significant predictors of variations in residual mortality throughout the US, even after controlling for socio-economic factors. Analysis of 12 years of daily mortality and air pollution in New York City showed that aerosol extinction coefficient (b/sub ext/), a good surrogate for fine particles, is significantly associated with observed mortality. 62 refs., 2 figs., 13 tabs.
