Description of key information

The toxicity of polysulfide di-tert-nonyl to algae has been read across from polysulfide di-tert-dodecyl. 72 hours of exposure of polysulfide di-tert-dodecyl at its saturation concentration (0.08 mg/L) was found not to inhibit the growth of Pseudokirchnerella subcapitata.

Key value for chemical safety assessment

Additional information

The toxicity of polysulfide di-tert-nonyl to algae has been read across from polysulfide di-tert-dodecyl. Thiebaud (2000) is a GLP-compliant guideline study showing the growth inhibition effect of polysulfide di-tert-dodecyl on Pseudokirchnerella subcapitata over 72 hours. The maximum level of exposure, the saturation concentration (0.080 mg/L), resulted in no inhibition of the growth of Pseudokirchnerella subcapitata. The study is considered reliable and suitable for use for this endpoint.
