Includes bibliographical references. "The Aquatic Effects Technology Evaluation Program (AETE) is in the process of evaluating methods and approaches to environmental monitoring, for potential application in the EEM for metal mining. As a part of this programme a series of sediment toxicity tests are being examined for use in this national programme. Among the suite of tests being evaluated is the Tubifex tubifex 28-day adult reproduction test. Samples from 63 sites at three mining locations were examined. The functional responses of T. tubifex (survival and reproduction) were compared to acceptability criteria derived from reference sites sampled in the five Great Lakes over a 3 year period. Three categories of toxicity were developed based on results from 166-208 reference sediments. The 63 sites were classified according to the responses as 1) non toxic, 2) potentially toxic or 3) toxic. These results showed little evidence of toxicity at these particular sites"--Abstract. gccst Bioassay Reynoldson, Trefor B., author. Hoekstra, P., author. Canada. Environment Canada.
