Description of key information

A short-term toxicity test with the marine copepod (Acartia tonsa) exposed to COASOL and conducted under GLPs, static conditions, and following standard test guidelines (ISO TC147/SC5/WG2), resulted in 48-hour LL50 value of 25 mg/L

Key value for chemical safety assessment

Marine water invertebrates

Effect concentration:
25 mg/L

Additional information

One short-term aquatic (marine water) invertebrate toxicity study was available for COASOL and considered reliable for assessment of this endpoint. The study was conducted with the marine copepod (Acartia tonsa) and found to be of good quality and assigned a Klimisch score of one. Due to the limited water solubility of the test substance, the organisms were exposed to water-ammodated fractions resulting from solutions prepared at a nominal loading rates of 10, 18, 32, 56, and 100 mg/L. The study was conducted for 48-hours, under static conditions, following United Kingdom Proposal ISO TC147/SC5/WG2, and under GLPs. The study concluded the 48-hour LL50 value was 25 mg/L and considered the key parameter for this endpoint.
