Suspended and bottom sediment samples were tested using four species of freshwater benthic invertebrates in chronic exposure studies. The endpoints that were measured included survival, growth (amphipod, chironomid and mayfly) and reproduction (oligochaete worm). The test results were compared with standard reference sediment samples from Long Point Marsh, Ontario, for biological quality assurance."--Study perspective. |
