Recommandations pour la qualité de l'eau au Canada : trichloroéthylène by Dwayne R. J Moore( Book )

4 editions published in 1991 in French and held by 9 WorldCat member libraries worldwide

On a examiné la documentation relative aux utilisations, au devenir et aux effets des chloroéthanes sur l'eau naturelle utilisée comme eau potable non traitée, sur la vie aquatique en eau douce, sur l'utilisation de l'eau pour l'agriculture, sur la qualité de l'eau pour les loisirs et l'esthétique, ainsi que sur les approvisionnements en eau pour l'industrie. Ces renseignements sont résumés dans cette publication. A partir de cette étude, des lignes directrices sur la qualité de l'eau sont recommandées pour la protection d'utilisations particulières de l'eau
Scoping science assessment of the impacts of freshwater aquaculture on the Canadian environment by S. L Walker( )

2 editions published in 2003 in English and held by 8 WorldCat member libraries worldwide

"Environmental impacts of aquaculture vary from minimal to severe impairment depending upon the site characteristics, the type, size and practices of the operation, and the nature of the wastes in the aquaculture effluent. The most common impact of aquaculture is nutrient enrichment potentially resulting in eutrophication. Other potential changes include deterioration of water quality, changes in physical and chemical characteristics of the sediment, shifts in algal and invertebrate communities, increase of birds around net cages, and increased interactions, disease transmission, and competition between farmed and wild fish. A review of the existing environmental monitoring programs indicates a lack of consistency across Canada"--Abstract

Recommandations pour la qualité des eaux côtières et estuariennes au Canada : polychlorobiphényles by Dwayne R. J Moore( Book )

5 editions published in 1991 in French and held by 7 WorldCat member libraries worldwide

Les polychlorobiphényles constituent un groupe complexe de composés d'hydrocarbures chlorés qui sont présents dans tout l'environnement. On les fabrique depuis longtemps car leurs utilisations sont nombreuses et leur persistance dans l'environnement est grande. Ce document présente une étude sur les propriétés physiques et chimiques des polychlorobiphényles, leurs concentrations dans l'environnement marin, leur devenir et persistance, leur bioaccumulation, et leur toxicité pour le biote marin. On trouvera dans cette publication un résumé de l'information sur le sujet

Canadian water quality guidelines for polychlorinated biphenyls in coastal and estuarine waters by Dwayne R. J Moore( Book )

5 editions published in 1991 in English and held by 3 WorldCat member libraries worldwide

Polychlorinated biphenyls (PCBs) are a complex group of chlorinated hydrocarbon compounds that are widespread in the environment. Serious concerns about PCB contamination have been raised because of their persistence in the environment, their tendency to bioaccumulate in biota, and their chronic toxicity effects on biota. These concerns have resulted in Canadian government actions to halt the import and production of PCBs and ensure their safe disposal. In Canada and the US, water quality guidelines have been established at levels that ensure the protection of freshwater aquatic biota. However, whereas a water quality guideline has been established in the US for marine aquatic biota, none has yet been established in Canada. This report presents a Canadian water quality guideline for PCBs that ensures the protection and maintenance of marine aquatic biota by considering the physical and chemical properties of PCBs, their concentrations in the marine environment, their fate and persistence, their bioaccumulation, and their toxicity to marine biota
