Figure 1. Human serum concentrations of PFOA and PFOS within different subpopulations of exposure in the United States.

Figure 1

A literature review was conducted to determine concentrations of PFOA and PFOS in human serum of United States residents (Chang et al., 2014, Emmett et al., 2006, Gleason et al., 2015, Landsteiner et al., 2014, Lau, 2012, Olsen et al., 2007). Populations were categorized into three different groups based on the potential for exposure to either compound. General population data was collected from human blood banks across the United States and National Health and Nutrition Examination Survey (NHANES) data. Concentrations reported in the polluted city residents category included data collected from residents in the surrounding areas of the 3M facilities (Cottage Grove, MN and Decatur, AL) and the DuPont facility (Parkersburg, WV) responsible for the production of PFOA and PFOS. Concentrations reported in the occupational exposure group were observed in the serum samples collected from workers of the 3M and DuPont facilities.
