Mercury Distribution in Water, Streambed Sediment, and Fish

Map of Study Location
  • Objectives:
      Determine the current level of mercury bioaccumulation in gamefish species in urban, mining, agricultural, and reference areas.

      Determine the level of mercury exposure to gamefish in stream ecosystems representing the four land-use types.

  • Approach:
      Eight sites have been selected representing urban, mining, agriculture, and reference conditions. The sites will be sampled once for fish tissue, streambed sediment, and stream-water quality.

  • Timing:
      Each site will be visited once during the first two weeks of August 2002.

  • Targeted Constituents:
      Fish tissue will be analyzed for total mercury. Stream water and streambed sediment will be analyzed for methylmercury and total mercury.
