Book excerpt: The Working Party finalized a review of chlorinated hydrocarbon substances in the African aquatic environment; the review is annexed to this report. The Working Group concluded that it had achieved its major goal to evaluate the state of the African aquatic environment and to review major groups of pollutants that could have negative impacts on aquatic life and fishery resources, i.e. organic matter, metals and organochlorine substances. Future studies could concentrate on phosphorus loads causing eutrophication and on the state of specific types of water bodies in Africa. The Working Party discussed its potential role in the preparations for the CIFA Seminar on African inland fisheries, aquaculture and the environment, scheduled for December 1994, and made suggestions for major inputs it could provide to the seminar.
