Water quality - Determination of the chronic toxicity to Ceriodaphnia dubia

<p>ISO 20665:2008 specifies a method for the determination of the chronic toxicity to <i>Ceriodaphnia dubia</i> (Cladocera<i>, </i>Crustacea), based on reproduction inhibition after (7 ± 1) d.</p> <p>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).</p> <p>ISO 20665:2008 is not applicable to the testing of aquatic samples from the estuarine or marine environment.</p>
