The Toxicity of 2,4-D and Picloram Herbicides to Fish.

摘要

Two common herbicides, picloram or Tordon (4-amino-3, 5, 6-trichloropicolinic acid) and 2, 4-D (2,4-dichlorophenoxyacetic acid) and their salts exhibit low toxicity to fish. Certain formulated derivatives (especially esters) tend to be more toxic than acid salts as an impurity from technical picloram. Even with picloram containing impurities,adaptive and/or detoxification responses by the fish are indicated. These herbicides (picloram and 2,4-D) seem to present a low potential hazard to fish from normal agricultural or industrial use. (Author)
