  • Ecotoxicology and Water Quality Standards

    Abstract : The establishment of water quality objectives (WQO) for individual chemicals is a complex process fraught with many uncertainties. WQO should (in principle) be derived from no-observed-effect-concentrations (NOEC\'s) determined experimentally on selected test species and even preferably on biological communities in field situations. In practice this is seldom the case. The number of ...
