METHODS: PM data were obtained from the U.S. Environmental Protection Agency (EPA) National Exposure Research Laboratory Platform in central Phoenix. We obtained gaseous pollutant data, specifically carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), and sulfur dioxide (SO2) data, from the EPA Aerometric Information Retrieval System Database. We used Poisson regression analysis to evaluate the associations between air pollution and non-accidental mortality and cardiovascular mortality.
RESULTS: Total mortality was significantly associated with CO and NO2 (p < 0.05), and weakly associated with SO2, PM(10), and PM(CF) (p < 0.10). Cardiovascular mortality was significantly associated with CO, NO2, SO2, PM(2.5), PM(10), PM(CF) (p < 0.05), and elemental carbon.
CONCLUSIONS: Factor analysis revealed that both combustion-related pollutants and secondary aerosols (sulfates) were associated with cardiovascular mortality.
