Strong evidence now supports the notion that organophosphate pesticides damage the fetal brain and produce cognitive and behavioral dysfunction through multiple mechanisms, including thyroid disruption. A regulatory ban was proposed, but actions to end the use of one such pesticide, chlorpyrifos, in agriculture were recently stopped by the Environmental Protection Agency under false scientific pretenses. This manuscript describes the costs and consequences of this policy failure and notes how this case study is emblematic of a broader dismissal of scientific evidence and attacks on scientific norms. Scientists have a responsibility to rebut and decry these serious challenges to human health and scientific integrity.

现在，有力的证据支持以下观点：有机磷酸酯农药会通过多种机制（包括甲状腺功能紊乱）破坏胎儿的大脑，并导致认知和行为功能障碍。有人提出了一项管制禁令，但是环境保护局最近以错误的科学幌子停止了在农业中停止使用此类农药毒死rif的行动。该手稿描述了此政策失败的代价和后果，并指出了本案例研究如何象征着更广泛地摒弃科学证据和对科学规范的攻击。科学家有责任反驳和谴责这些对人类健康和科学诚信的严峻挑战。
