Aerosols in the agricultural setting.

This report summarizes discussions chaired by Kent Pinkerton held during the New Paths: Health and Safety in Western Agriculture conference, November 11-13, 2008. Research on air quality and aerosols in the agricultural setting was presented and discussed, providing insight into critical issues by many of the prominent scientists in this field. The panel discussion provided an overview of recent advances and future directions for research regarding sampling and exposure assessment of biologically active aerosols. This analysis considers chemical composition, individual exposures, and subsequent health effects experienced in large- and small-scale farming operations. The breakout discussion focused on other sources of particulate matter associated with agricultural activities prominent in various regions of the western United States. The complementary directions for these discussions fully demonstrate the wide range of concerns and issues that exist regarding bioaerosols and ambient dust associated with agricultural activities.
