Study examined a broad range of CECs in marine waters and whole-body fish, which is uncommon in the literature.

Analytes in effluent higher than most concentrations reported for large wastewater treatment plants in the United States.

Whole-body fish tissue concentrations of CECs elevated for some analytes and occur at greater than expected concentrations.

Several compounds were observed at concentrations that may result in adverse responses in biota.

Loading of CEC analytes to estuaries considered substantial and expected to increase with human population growth.
