A preliminary risk assessment was undertaken on the Kenyan part of Lake Victoria to identify the major causes of degradation of water quality. Urban, industrial and agricultural loads were quantified and related to geographical and climatic conditions. A few analyses of persistent contaminants were carried out on fish. Monthly limnological investigations were conducted together with river water quality analyses. Phosphorus loads and consequent eutrophication were identified as the major causes of water quality degradation.
