A method for measuring algal toxicity and its application to the safety assessment of new chemicals

, : A method for measuring algal toxicity and its application to the safety assessment of new chemicals. Proceedings and Report of Meeting on Agrochemical Residue Biota Interactions FAO/IAEA, 1978: 171-180

An algal toxicity test was developed on the basis of the Algal Assay Procedure (Bottle Test), modified for toxicity assessment. A 5-day exposure of freshwater or marine unialgal cultures to a range of test material concns. is followed by a 9-day recovery period in the absence of the test material.
