Description of key information

The concentrations of sodium ethyl xanthate (CAS# 140-90-9) were measured at the beginig of the study. Toxicity of the compounds depends on temperature. Decrease with increasing temperature.

Key value for chemical safety assessment

LC50 for freshwater fish:
0.01 mg/L

Additional information

The listed toxicity on fish of different xanthates indicate that potassium ethyl xanthate (CAS# 140-89-6) is much more toxic than sodium ethyl xanthate (CSA# 140-90-9) and toxicity of the latest one is not much higher than sodium isobutyl xanthate. The toxicity decrease sharply with increasing temperature.
