ISO 19827:2016
Water quality — Determination of the acute toxicity to the freshwater rotifer Brachionus calyciflorus
ISO 19827:2016(E) specifies a method for the determination of the lethal effects of toxicants to Brachionus calyciflorus after 24 h exposure.
The method is applicable to:
a) chemical substances which are soluble, or which can be maintained as a stable suspension of dispersions under the conditions of the test;
b) industrial or sewage effluents, treated or untreated, if appropriate after decantation, filtration or centrifugation;
c) freshwaters;
d) aqueous extracts.
