^aConcentrations below the limit of detection were included in analysis as one‐half the lowest calibration standard concentration (0.5 ng/ml for MEP and 0.05 ng/ml for all other compounds). Calculations exclude recapture sample for F209.

^bGeometric mean (GM) and (95% confidence interval).

^cMedian and (interquartile range).
