Results of a technology demonstration project to compare rapid aquatic toxicity screening tests in the analysis of industrial effluents
Abstract
The results of a ‘BioWise’ demonstration project to assess the comparative sensitivity and practicality of seven new assays for the direct assessment of ecotoxicity in industrial effluents are presented. In addition the aim of the project was to validate the results of the new assays against benchmark data generated from non-proprietary, rapid, microplate screening assays using the regulatory species; freshwater crustacean Daphnia magna and green algae Selenastrum capricornutum, chosen in view of their environmental relevance. The new commercial test assays were: Daphnia magna, Selenastrum capricornutum and Thamnocephalus platyurus Toxkits® supplied by Vickers Laboratories Ltd, containing dormant, immobilised life stages of the test species; GreenScreen®
