Health Consultation: Exposure Investigation. Biological Monitoring for Exposure to Herbicides, Highway 36 Corridor, Lane County, Oregon. Cost Recovery Number: AA1200, March 5, 2012.

摘要

The Agency for Toxic Substances and Disease Registry (ATSDR), the Pesticide Analytical Response Center (PARC) led by the Oregon Health Authority (OHA), and the Environmental Protection Agency (EPA) conducted an Exposure Investigation (EI). The purpose of this EI was to assess whether, and to what extent, residents of western Lane County, Oregon, who live near clear-cut areas, are being exposed to the herbicides, atrazine and 2,4-dichlorophenoxyacetic acid (2,4-D). In this EI, we conducted urine biomonitoring in 64 volunteers from 38 households who live near forested areas where herbicides are applied to tracts of land that have been recently clear-cut. While forestry is the predominant land use in this area, pesticides are also used within or near the sample area for agricultural, road right-of-way, residential, and other uses.
