Aquatic Toxicity A highly successful l l t h Annual Aquatic Toxicity Workshop was held 13-15 November, 1984, in Vancouver, B.C., organized and sponsored by local universities, the federal and provincial governments, industry and consulting firms. Topics discussed included the effects of mine wastes on aquatic systems, the impact of acidification and metals on freshwater biota, the relationships between environmental pollutants and fish disease/health, and environmental questions pertaining to the off-shore oil industry. Twenty-four papers, including some very comprehensive reviews, were resented on these topics, and 22 papers were given on other research ranging from pesticides to contaminated sediments. Information can be obtained from the Workshop chairman, Dr. G. H. Geen, Dept. of Biological Sciences, Simon Fraser University, Burnaby, B.C. V5A 156. Proceedings will be published in 1985. 84
The Aquatic Toxicity Workshops are continuing very actively, with the next ones planned for Thunder Bay/ Duluth (1985), Moncton, N.B. (1986) and Toronto (1987). The Workshops are dedicated to an exchange of knowledge and ideas on aquatic and environmental toxicology, and provide an annual focus in Canada on the principles, current problems and approaches, and applications of the knowledge in this field. Information on any aspect of the workshops, and copies of past proceedings (1981 onwards) can be obtained from Mr. Michael Gilbertson, Continuity Chairman, Fish Habitat Management Branch, Dept. of Fisheries and Oceans, 200 Kent Street, Ottawa, Ontario, K I A 0E6, or from Dr. P. G. Wells, 1984-85 Chairman, National Steering Committee, Aquatic Toxicity Workshops, Toxic Chemicals Management Program, Environment Canada, Ottawa, Ontario, K1A 1C8.
