Description:

Objective:

The objective of this research project is to assess the cumulative effect of long-term exposures to particulate matter (PM).

This is one of 10 projects funded by the Center. The progress for the other nine projects is reported separately (see reports for R827353C001 through R827353C005, and R827353C007 through R827353C011).

Progress Summary:

We have followed up the Harvard Six Cities Study cohort in an effort to assess the cumulative effect of long-term exposures to PM on the incidence of lung cancer, nonmalignant respiratory disease, cardiovascular disease, and cause-specific mortality. More specifically, vital status was determined for the 8,111 participants in the Harvard Six Cities adult cohort for an additional 9 years of followup (1990-1998). We identified 1,430 additional deaths, bringing the total to 2,737 deaths.

Survival analyses of all-cause mortality shows that life expectancy continues to be reduced in the more polluted cities, with the survival relative ranking being the same as that observed in the original study. Monitoring of PM2.5 and PM10 was included as part of the original study, but it was not continued in the more recent period of followup. Therefore, we have been modeling PM2.5 for this time period using data from nearby monitors in the U.S. Environmental Protection Agency Air Quality System monitoring network. A paper showing a decrease in the relative risk from mortality consistent with decreased air pollution levels in specific cities is in preparation by Laden, et al. . This paper, as well as one in preparation by Schwartz, et al. (2004), also focuses on the effect of yearly changes in PM2.5.

Future Activities:

We will continue to assess the cumulative effect of long-term exposures to PM and submit papers for publication that focus on the decrease in the relative risk from mortality consistent with decreased air pollution levels in specific cities and the effect of yearly changes in PM2.5.
