Application of Risk Assessment book
This chapter provides an example of how a risk assessment is applied to a specific substance in a specific setting. The air pollutant chosen for this example is particulate matter (PM). PM is chosen in large part because it is ubiquitous and because there are substantial scientific controversies over the health effects resulting from low-level exposures occurring indoors and outdoors. PM is regulated by the Environmental Protection Agency as a criteria air pollutant. Criteria pollutants are defined as pollutants whose sources are numerous and diverse. They were originally assumed to be pollutants for which a safe level of exposure could be established, although more this assumption is being challenged in certain cases. Human health effects resulting from exposures to air pollutants are usually assessed through methods involving statistical techniques. Because there is reasonable access to detailed data on populations, exposures, and hospital records, epidemiological studies are widely used.
