| Abstract: |
| Changes in levels of heavy metals in seawater resulting from the addition of mine tailings were studied using plastic enclosures.Nominal concentrations of 10 mg l-1 and 100 mg l-1 of mine tailings from a B.C.molybdenum mine were added, and the metal levels were followed together with sedimentation rates, particle size distribution and other oceanographic and biological time-series parameters over sixteen days.No substantial elevation in levels of zinc, cadmium and copper was observed in the tailing bags compared to that in a background control bag with no addition of tailings.Lead showed a substantial increase in seawater following tailing addition and its removal apparently was with detritus settling following a plankton bloom, and inorganic settling of fine tailing particles. |
