Water quality - Determination of chronic toxicity to Ceriodaphnia dubia
|Publication Date:||15 December 2008|
|ICS Code (Examination of biological properties of water):||13.060.70|
This International Standard specifies a method for the determination of the chronic toxicity to Ceriodaphnia dubia (Cladocera, Crustacea), based on reproduction inhibition after (7 ± 1) d.
The method is applicable to:
a) chemical substances which are soluble or which can be maintained as stable suspensions or dispersions under the conditions of the test;
b) industrial or sewage effluents, if appropriate after decantation, filtration or centrifugation;
c) fresh waters;
d) aqueous extracts.
This International Standard is not applicable to the testing of aquatic samples from the estuarine or marine environment.
