Given the many detrimental effects on wildlife and laboratory animals, the large number of studies from so many independent laboratories, and the associated effects in humans, it is not likely that the observed effects are mistakes, misinterpretations, or artifacts. In particular, given atrazine’s solubility in water, aquatic animals such as fish and amphibians are at the greatest risk. Salmon and trout which are commercially important are at risk as are the economies that depend on healthy fish. Several salmon and trout species are already endangered or threatened as are other fish. Amphibians are also very sensitive to endocrine disruptors and given that already more than 60% of all amphibians are in decline and a third are threatened or endangered, atrazine is of great concern and several studies suggest that pesticides (including atrazine) may be an important factor in declines [1-7]. Atrazine has already been banned as a result of lawsuits to protect two endangered amphibians and similar cases are developing for endangered fish (see below).
