Top 25 contaminants detected in composite water samples from the Maumee AOC in 2016 that were found to most strongly covary with endogenous metabolite profile changes found with polar extracts of liver tissue collected from associated caged male fathead minnows. The analysis was conducted in two different batches comprised of upstream (BCR16, GRM16, FMP16, PBG16) and downstream sites (USC16, SCR16, UTP16, TWP16). An X in the column headed Upstream or Downstream indicates the presence of the contaminant in the top 25 for the given batch. (See text for analysis details).
