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.
