We have studied the effect of two detoxifying factors (UV radiation from different sources and humic substances) on the toxicity of alcoholic solutions of substituted coumarins. The change in the characteristics of the substituted coumarins was monitored spectrophotometrically. The toxicity of solutions of the substituted coumarins was monitored using a bioluminescence test system. We have shown that efficient detoxification of an alcoholic solution of coumarins occurs as a result of addition of humic substances. We have observed a dependence of the detoxification both on the structure of the studied compounds and on the characteristics of the source.
