Short-term toxicity to aquatic invertebrates

Description of key information
No effects up to a loading rate of 100 mg/L (OECD 202, Acartia tonsa)
Key value for chemical safety assessment
Additional information
One saltwater study is available on the short-term toxicity of Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) to aquatic invertebrates.
The key study conducted with Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) was performed according to the OECD Guideline 202 and GLP (Hudson, 2003). The test organism Acartia tonsa was exposed to the test substance in a static system for 48 hours, at nominal test concentrations of 1000, 1800, 3200, 5600 and 10000 mg/L. Immobilisation was observed at the highest test concentration, and an EC50 of 7756 mg/L was derived. Although the test solutions were prepared as water accommodated fractions (WAF), physical effects caused by undissolved test material cannot be excluded. The sudden increase in mortality from 0% at concentrations up to 1000 - 5600 mg/L to 100% at 10,000 mg/L, is more likely to be caused by the amount of undissolved test material in the test solution, leading to immobilisation of the daphnia, rather than a systemic toxic effect.
