A Measure of Community Exposure: PFOA in Well Water Correlates with Serum Levels

摘要

The first detailed investigation into contamination of private wells with perfluorooctanoic acid (PFOA) and levels of the compound in human blood serum suggests that drinking water was the dominant source of exposure to PFOA in a community industrially exposed to the compound [EHP 119(1):92–97; Hoffman et al.]. The study, conducted in 2005 and 2006, included only people who obtained their drinking water from private wells. The results showed that each 1-μg/L increase of the compound in the participants’ water supply was associated with a 141.5-μg/L increase in people’s serum PFOA concentrations.
