Sammendrag:

ISO 17244:2015 specifies a method for determining the effects of chemical and aqueous samples on the embryo-larval development of marine bivalves. It allows the determination of the concentration levels that result in an abnormality in embryo-larval development. This test is suitable for salinity ranges between 20 and 40 for mussels and between 25 and 35 for oysters. This method applies to

- chemical substances and preparations,

- marine and brackish waters,

- streams and aqueous effluents (urban, agricultural, industrial effluents, etc.) as long as the salinity is adjusted and/or dilution is limited so that the aforementioned salinity ranges are respected, and

- aqueous extracts (pore water, elutriates, eluates, and leachates) from sediments and petroleum products.
