Table 2. Measured and estimated PFOA exposure concentrations (ng/mL) in the cohort (n = 32,254).
Cohort Median (range)
aWorkers who did not participate in the C8 Health Project did not have serum levels measured (n = 1,823) and other workers were missing measurements (n = 9). bCommunity residents were followed for an average of 32 years, and ­workers were followed for an average of 38 years.
