Water quality - Determination of chronic toxicity to Ceriodaphnia dubia

PUBLISH DATE 2008
ISO 20665:2008

ISO 20665:2008 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:

  • chemical substances which are soluble or which can be maintained as stable suspensions or dispersions under the conditions of the test;
  • industrial or sewage effluents, if appropriate after decantation, filtration or centrifugation;
  • fresh waters;
  • aqueous extracts (leachates, eluates, and elutriates).

ISO 20665:2008 is not applicable to the testing of aquatic samples from the estuarine or marine environment.
