Water quality - Determination of the acute toxicity to the marine rotifer Brachionus plicatilis - First Edition
N 19820
Annotation
This International Standard specifies a method for the determination of the lethal effects of toxicants to Brachionus plicatilis after 24 h or 48 h exposure.
The method is applicable to the following:
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) marine or estuarine waters;
d) sediment elutriates/eluates
