Description of key information

Additional information

No data are available for Trichloro(3-chloropropyl)silane. Reliable acute aquatic toxicity tests results for freshwater fish (Brachydanio rerio), invertebrates (Daphnia magna) and algae (Scenedesmus subspicatus) are however available from a read-across substance (3-chloropropyltrimethoxysilane (2530-87-2)) that shares the same hydrolysis products. LC50 or EC50 values for the three organisms were >100, 869 and >833 mg/L respectively. A NOEC of 167 mg/L was determined in the algal test. It is likely that the test organisms were exposed to the hydrolysis products of the substance.
