This International Standard specifies a method for the determination of lethal as well as sublethal effects of contaminated sediments on the ostracod crustacean Heterocypris incongruens after 6 d exposure. The method is applicable not only to fresh water sediments, but also by extension to solid wastes and soils after addition of (uncontaminated) water. The method can also be applied to chemicals or preparations which are spiked into a reference sediment. This International Standard is not applicable to the testing of sediments from the estuarine or marine environment.
Abstract
Overview
ISO 14371:2012 defines a standardized bioassay to assess freshwater sediment toxicity using the ostracod crustacean Heterocypris incongruens. The method measures lethal (mortality) and sublethal (growth inhibition) effects after a 6-day direct-contact exposure to whole sediments. It is applicable to freshwater sediments and, by extension, to solid wastes and soils following the addition of uncontaminated water. The standard is not intended for estuarine or marine sediments.
Key topics and technical requirements
- Test organism: Neonates of Heterocypris incongruens hatched from dormant cysts (no continuous culture required).
- Exposure duration: 6 days; endpoints are percentage mortality and, if mortality is low (e.g.
