ISO 6341.2012 specifies a method for the determination of the acute toxicity to Daphnia magna Straus (Cladocera, Crustacea). This method is applicable to: chemical substances which are soluble under the conditions of the test, or can be maintained as a stable suspension or dispersion under the conditions of the test; industrial or sewage effluents; treated or untreated waste water; aqueous extracts and leachates; fresh water (surface and ground water); eluates of fresh water sediment; pore water of fresh water sediment.
Abstract
Overview
EN ISO 6341:2012 (ISO 6341:2012) specifies a standardized laboratory bioassay to determine the acute toxicity of chemicals, waters and waste waters to the freshwater crustacean Daphnia magna. The method measures inhibition of mobility (immobilization) after 24 h or 48 h exposure and reports effect concentrations such as the EC50 (effective concentration causing 50% immobilization). The standard applies to soluble substances or stable suspensions, industrial and sewage effluents, treated/untreated wastewater, aqueous extracts and leachates, fresh waters, sediment eluates and pore waters.
