Inventories conducted between June 22 and July 31, 1979 and June 12 and July3, 1980 to determine the sport fish potential of the lakes, assess the impactof commercial development on the sport fish populations and provide baselinedata to permit development of an allocation and use strategy for the fisheries resource.

Investigation to identify potential problems in the handling and disposal of coal-fuelled atmospheric fluidized-bed combustion residues, emphasizing thepractical aspects and the bulk properties of the residues. A summary ofexisting published knowledge is given, then a summary of field experience, focusing on the thermodynamics of the exothermic reaction ofcalcuim oxide and water. Various methods of waste handling are consideredand general recommendations are proposed.

Explicit standard or reference methods for measuring the acute lethal toxicity of effluents to rainbow trout (oncorhynchus mykiss) are provided in this report. Specific instructions for performing and reporting acute lethality tests with samples of effluent are given, and the guidance provided in the generic methodology report Àcute lethality test using rainbow trout' is extended.

Bis(2-ethylhexyl) phthalate [also known as di(2-ethylhexyl) phthalate or DEHP] is the most important phthalate plasticizer used in Canada. Production in Canada in 1991 totalled about five kilotonnes and an additional five kilotonnes were imported. This report gives a summary of information critical to the substance's assessment as toxic, including identity, properties, production, and uses; entry into the environment; fate and concentration; toxicokinetics; and effects on experimental animals and in vitro and in humans; and ecotoxicology. Its assessment as toxic under the Canadian Environmental Protection Act (CEPA) is described for the environment, the environment on which human life depends, and human life or health.

Municipal wastewater effluents include both sanitary sewage and stormwater, and are one of the largest sources of pollution by volume in Canadian waters. The first part of this report describes the characteristics of municipal wastewater effluents, their significance as a pollution source, and the factors influencing the effects of these effluents. Part two assesses the effects of municipal wastewater effluents on the environment (including nutrient enrichment, oxygen depletion, and direct toxicity), on human health, and on the economy. Part three reviews the management of municipal wastewaters in Canada, initiatives to improve wastewater management, and continuing & emerging problems such as ageing infrastructure and endocrine disruption.

A study was undertaken by Environment Canada, in conjunction with the US Environmental Protection Agency (EPA), Alberta Environment and 15 industrial participants involved in developing or marketing solidification technology, to develop and validate 16 laboratory test methods for evaluating the physical and chemical properties of solidified wastes. Environment Canada and the US EPA provided the 15 industrial participants with 5 untreated hazardous wastes, which were then treated with their proprietary processes and returned as solidified products to 4 laboratories in Canada and the US for testing. Seven physical tests, 5 leaching tests, and 4 micromorphological characterization methods were applied to the solidified products.

This dictionary has been improved through the addition of English definitions, parallel to the existing French definitions, while all equivalencies have been reviewed in light of the most up-to-date sources. The terms are in alphabetical order according to the English key terms, and it includes a French-English glossary. The terms in the new dictionary remain essentially the same, with approximately 1,000 concepts and some 3,000 terminological units in the two official languages. It covers three sub-fields, namely physicochemical reactions involving ozone in the atmosphere, atmospheric layers, and the symptomatology of skin cancers caused by the sun's rays.
