Ecotoxicity assessment aims at predicting the effects of pollution on biological organisms and preventing or remedying any harmful effects in the most efficient and effective way. Mérieux NutriSciences offers a wide range of specific analyses to assess the potential risk of pollutants, waste, products and substances in ecosystems. Laboratory studies are carried out on algae, crustaceans (Daphnia and Artemia) and fish.
Wherever possible, ecotoxicological studies are accompanied by tests to verify the concentration and stability of the test substance in the sampling system.
Seaweed and aquatic plants
Inhibition studies on algae growth are performed using different study methods, in compliance with the current OECD and ISO Guidelines. According to the request, studies on algae can be carried out with different species of freshwater or marine waters green algae.
Acute toxicity studies are performed on Daphnia magna and other invertebrates (e.g. Artemia). Test design is customized according to the different needs of the customer and in full compliance with the test element or application technique.
Acute toxicity studies, as well as studies on early life cycle and life cycle itself (two-generation tests) are conducted on cold or warm water fish such as Oncorhynchus mykiss, Brachiydanio rerio, Cyprinus carpio and Pimephales promelas. Depending on the aim of the study, static, semi-static or flow-through tests are performed.
Acute toxicity studies are conducted under static or semi-static conditions on Brachiydanio rerio. Other species provided for by the official guidelines (e.g. OECD) can be introduced upon specific customer’s request.
