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: 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 (leachates, eluates, and elutriates). ISO 20665:2008 is not applicable to the testing of aquatic samples from the estuarine or marine environment.
Abstract
Overview
ISO 20665:2008 defines a standardized chronic toxicity test using the cladoceran Ceriodaphnia dubia to assess water quality. The method measures reproduction inhibition after (7 ± 1) days of exposure to a range of concentrations of a test sample. It is widely used for evaluating soluble chemicals, stable suspensions, industrial or sewage effluents (after pre‑treatment if needed), fresh waters and aqueous extracts (leachates/elutriates). The standard is not applicable to estuarine or marine samples.
