根据一份报告,全世界最常用的除草剂阿特拉津(Atrazine)可能与两柄类的内分泌失调有关,而且可能对全世界两栖类物种的衰退有贡献。这种化学除草剂在欧盟被禁用,但是美国环保署在2006年得出结论说还没有足够的数据可以确定阿特拉津是否会影响到两栖类的发育。 According to one report, Atrazine, the most commonly used herbicide in the world, may be related to the endocrine disorders of the bipotentials and may contribute to the decline of amphibian species throughout the world. The chemical herbicide was banned in the EU, but the EPA concluded in 2006 that there was not enough data to determine whether or not atrazine affected amphibian development.
