title: [Toxic effects of pyrogallol to three different aquatic organisms].
abstract: OBJECTIVE
  To study the toxic effects of pyrogallol on aquatic organisms.
  
  
  METHODS
  The acute toxicities of different concentrations of pyrogallol on Chlorella pyrenoidosa, Scenedesmus obliquus and Moina macrocopa were studied.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Pyrogallol had moderate toxicities on Chlorella pyrenoidosa, Scenedesmus obliquus and Moina macrocopa.
