Book excerpt: In dit rapport worden criteria genoemd voor de waterkwaliteit van Europese zoetwatervis en het bevat een kritisch literatuuroverzicht over de aanwezigheid en de effecten van nikkel in zoetwater. De werkingswijze van nikkel en de factoren die de korte en langdurige toxiciteit tijdens de verschillende levenscycli van vis beinvloeden, zijn gedetailleerd weergegeven

Book excerpt: For water pollution control purposes, the concentration-addition model for describing the joint effects of mixtures of toxicants on aquatic organisms is appropriate; in this model the contribution of each component in the mixture is expressed as a proportion of the aqueous concentration producing a given response in a given time. Examination of available data using this model shows that for mixtures of toxicants found in sewage and industrial effluents, the joint acutely-lethal toxicity to fish and other aquatic organisms is close to that predicted assuming simple addition of the proportional contribution from each toxicant. The observed median value for the joint effect of these toxicants on fish is 0.95 of that predicted, and the corresponding collective value for sewage effluents, river waters, and a few industrial wastes, based on the toxicity of their constituents, is 0.85, while that for pesticides is 1.3. The less-than-additive effect of commonly-occurring toxicants in some mixtures may be partly attributable to small fractions of their respective LC50 values having little or no additional effect.

Available in PDF, EPUB and Kindle. Book excerpt: Water Quality Criteria for Freshwater Fish, Second Edition, is a collection of 12 technical papers on water quality criteria for European freshwater fish, together with a report on fish toxicity testing procedures that have been produced for the European Inland Fisheries Advisory Commission (EIFAC)—an intergovernmental organization with a current membership of 24 countries. Each chapter reviews a particular water quality characteristic for European inland fisheries, although the effects of mixtures with other harmful substances have been described for some of them. These characteristics include water quality criteria for finely suspended solids and pH values; water temperature; the effect of ammonia; phenolic wastes; dissolved oxygen; chemistry and toxicology of chlorine; and toxicity of zinc, copper, and cadmium. The reports in this volume will be useful not only to the member countries of the European Inland Fisheries Advisory Commission, but also to those concerned with the management of inland waters and their fishery resources in other continents.

Book excerpt: This report, prepared by the European Inland Fisheries Research Advisory Commission Working Party on Water Quality Criteria for European Freshwater Fish, critically reviews the literature on the occurrence and effects of chromium in fresh water. It lists and discusses the sources of chromium, and its chemistry and analysis in fresh water. The mode of action of chromium and the factors which affect its short- and long-term toxicity to the various life-cycle stages of fish are dealt with in detail. Similar information for plants and invertebrates is considered and evidence for the accumulation of the metal in animals is reviewed. The tentative water-quality criteria proposed distinguish between salmonid and non-salmonid waters but, in order to protect sensitive species of invertebrates, it is recommended that criteria for salmonid waters should be used to cover the majority of waters. The conditions under which more or less stringent standards may be appropriate are indicated. To protect salmonid waters, the mean aqueous concentration of ̀soluble' chromium should not exceed 0.025 mg Cr/l and the 95 percentile should not exceed 0.1 mg Cr/l.
