TL;DR: In this large study, it was not able to detect an effect of ozone on the risk of death from cardiovascular causes when the concentration of PM(2.5) was taken into account, but a significant increase in the risk from respiratory causes was demonstrated in association with an increase in ozone concentration.

TL;DR: The results suggest the chronic health effects associated with within-city gradients in exposure to PM2.5 may be even larger than previously reported across metropolitan areas, and nearly 3 times greater than in models relying on comparisons between communities.

TL;DR: An extended follow-up and spatial analysis of the American Cancer Society Cancer Prevention Study II (CPS-II) cohort was conducted in order to further examine associations between long-term exposure to particulate air pollution and mortality in large U.S. cities.

TL;DR: Relatively low levels of fine particulate exposure from either air pollution or secondhand cigarette smoke are sufficient to induce adverse biological responses increasing the risk of cardiovascular disease mortality.

TL;DR: Using the first individualized exposure assignments in this important cohort, positive associations of fine particulate matter, O3, and NO2 with mortality are found and suggest that traffic pollution relates to premature death.
