To study the toxic effects of pyrogallol on aquatic organisms. The acute toxicities of different concentrations of pyrogallol on Chlorella pyrenoidosa, Scenedesmus obliquus and Moina macrocopa were studied. The algal cell densities and the quantity of the Moina macrocopa reduced significantly with pyrogallol concentration increased, exhibiting a good concentration-effects relationship. The EC50 of pyrogallol to Chlorella pyrenoidosa and Scenedesmus obliquus were 19.7 and 19.8 mg/L, respectively. The 28h and 48h EC50 of pyrogallol to Moina macrocopa were 18.25 and 13.96 mg/L, respectively. Pyrogallol had moderate toxicities on Chlorella pyrenoidosa, Scenedesmus obliquus and Moina macrocopa.
