Scope

This International Standard specifies a method for assessing 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 PSU and 40 PSU for mussels and between 25 PSU and 35 PSU 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,

— samples of contaminated sediment or dredged material.
