Water quality. Determination of the toxicity of water samples on the embryo-larval development of Japanese oyster (<i>Crassostrea</i> <i>gigas</i>) and mussel (<i>Mytilus</i> <i>edulis</i> or <i>Mytilus</i> <i>galloprovincialis</i>) Ingestion-build-79769 Ammonia solution manufacturers1 Scope This International Standard 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,
