Description of key information

Parent compound valeryl chloride: With high probability acutely not harmful to fish after pH-adjustment.

Key value for chemical safety assessment

Additional information

The acute fish toxicity of valeryl chloride (CAS 638 -29 -9) was determined with Leuciscus idus according to the German Industrial Standard DIN 38412, L15. The obtained LC50(96 h) was 68.1 mg/L (nominal). When tested under neutralised conditions (pH-adjustment), the LC50 was > 100 mg/L (nominal; BASF AG, 1987; report no.: 10F0207/875168).

In conclusion, valeryl chloride is considered to be with high probability acutely not harmful to fish.
