Chemicals of emerging concern in salmon streams

Overview of a project to identify chemicals of emerging concern (CECs) and quantify their concentrations in salmon streams with critical spawning and rearing habitat.

Chemicals of emerging concern (CECs) come from many different industrial wastes and products such as soaps, paints, home furnishings, and medicines. This study focuses on five classes of CECs including:

  • chlorinated paraffins (CPFs),
  • alkylphenols (APs),
  • alkylphenol ethoxylate (APE) surfactants,
  • polybrominated diphenyl ethers (PBDEs),
  • PFAS,
  • quinone transformation product of the tire rubber antioxidant N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine or 6PPD-quinone (6PPD-Q).

CECs have been largely overlooked in monitoring programs for stormwater-dominated streams, even though these streams are critical spawning and rearing habitat for salmon.
