This study evaluated the short-term effects of urban air pollution on cardiac hospital readmissions in survivors of heart attacks in five European cities. (more…)

Test results with laboratory mice show a direct cause-and-effect link between exposure to fine particle air pollution and development of atherosclerosis, commonly known as hardening of the arteries.

This study investigated the effects of air pollutants on birth weight among term infants who were born in California during 1975-1987 and who participated in the Children’s Health Study.

French researchers have reported that short-term ozone exposure within a period of 1 to 2 days is related to acute coronary events in middle-aged adults without heart disease, and that nitrogen dioxide and sulfur dioxide are not.

This study assessed effects of chronic exposure to air pollutants in University of California, Berkeley freshmen who were lifelong residents of the Los Angeles or San Francisco Bay areas.

Outdoor workers are considered populations at risk of ozone exposure, because of the time they spend out of doors and the increased dose they receive due to exercise.

The U.S. Environmental Protection Agency commissioned 3 meta-analyses of studies of ozone and mortality. Three separate research groups were asked to conduct a meta-analysis, using their own methods and study selection criteria. All three studies report a small but substantial association between daily ozone levels and total mortality.

Ozone air pollution has been associated with changes in daily mortality, but because high ozone days are generally quite hot, researchers seek to separate out the effect of temperature.

Using susceptibility criteria compiled from major regulatory and research reports, this study found that within the New England, New Jersey, and New York study areas, 38 percent of the population is under age 18 or over age 65 — age groups considered especially sensitive to PM pollution effects.

Analysts used the BENMAP model developed for U.S. EPA to assist in preparation of air pollution control policies to compare the impact of a the current annual average PM2.5 NAAQS of 15 µg/m3 with a more stringent standard of 12 µg/m3 in California.
