What Passive Sampling Tells Us

(1) Freely dissolved concentrations (Cfree) of contaminants of

√

concern (COC) in water around passive sampler

  • Surrogate for bioavailable concentrations of COC

– Pore water (Interstitial Water) – Water column

  • Compare to Water Quality Criteria (WQC), other water

quality standards, sediment guidelines or water-only toxicity data for exceedances (2) Concentration of COCs in passive sampler

√

  • Good correlation with bioaccumulation by aquatic organisms
  • Serve as surrogates for biomonitoring organisms

– Benthic and water column organisms – Fish consumed by humans

Why Do We Care about the Freely Dissolved Concentration (Cfree)?

exposure to bioavailable chemicals?

  • Sediment?
  • Food?
  • Pore Water = Freely dissolved concentration (Cfree)?

  • Freshwater midge (Chironomus tentans)
  • Exposure-response relationships
  • Survival versus exposure
