Water Quality Criteria for European Freshwater Fish

摘要: Abstract 1. For water pollution control purposes, the concentration-addition model for describing joint effects of mixtures toxicants on aquatic organisms is appropriate; in this contribution each component mixture expressed as a proportion aqueous concentration producing given response time (e.g. p 96-h LC50). 2. Examination available data using shows that found sewage and industrial effluents, acutely-lethal toxicity to fish other close predicted, assuming simple addition proportional from toxicant. The observed median value effect these 0.95 corresponding collective river waters, few wastes, based their constituents, 0.85, while pesticides 1.3. 3. less-than-predicted commonly-occurring tox...
