No effects up to the limit of water solubility for Scophthalmus maximus (OECD 203)

Key value for chemical safety assessment

Additional information

There is one reliable study on fish toxicity available for Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No.8007-43-0). For a second fish toxicity study only a short summary is available.

The saltwater key study conducted with Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No.8007-43-0) was performed according to the OECD Guideline 203 and GLP (Hudson, 2003). The marine fish Scophthalmus maximus was used as test organism. The fish were exposed to the nominal test concentration of 1000, 1800 and 3200 mg/L, prepared as water accommodated fractions (WAF). No mortalities were observed at any of the test concentrations, during the 96-hour test period, and a LC50 of > 3200 mg/L was reported.

In the supporting study conducted with Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No.8007-43-0), the test organism Salmo gairdneri was exposed to a test concentration of 100 mg/L. An LC50 (96h) of > 100 mg/L was reported. However, this result should be taken with caution because the original report was not available and the documentation was sufficient for assessment.
