BS ISO 20665:2008 Water quality. Determination of chronic toxicity to Ceriodaphnia dubia

BS ISO 20665 specifies a method for the determination of the chronic toxicity to Ceriodaphnia dubia (Cladocera, Crustacea), based on reproduction inhibition.

The method specified in BS ISO 20665 applies 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.
