Description of key information

The toxicity of Dioctyltin dichloride (CAS# 3459 -36 -7) to the fresh water green alga Scenedesmus subspicatus was determined in a 72-h growth inhibition test according to the OECD 201 test guideline. Nominal test concentrations of 10, 18, 32, 58 100 % of a 100 mg/L saturated stock solution were tested. No effect on cell growth was observed from any of the test solutions.
The EC50 value was considered to be > 0.0017 mg/L.

Key value for chemical safety assessment

Additional information

Rufli, 1988, did not produce a definitive value due to the poor solubility of the test substance. This study was not performed to GLP.

A reliability rating of 2 was assigned to this study, according to the criteria of Klimisch, 1997 as the study conducted in accordance with generally accepted scientific principles, possibly with incomplete reporting or methodological deficiencies, which do not affect the quality of the relevant results.
