Water quality. Growth inhibition test with the marine and brackish water macroalga Ceramium tenuicorne Ingestion-build-95349 Its specifications cover all lamps1 Scope This International Standard specifies a method for the determination of the inhibition of growth of the macroalga Ceramium tenuicorne by substances and mixtures contained in seawater or by waste water with salinities between 4S and 32S. This method is applicable to substances that are easily soluble in water. NOTE With modifications as described in ISO 14442[4] and ISO 566716[2], the inhibitory effects of poorly soluble organic and inorganic
