关于毒死蜱你需要知道什么

Chlorpyrifos is an organophosphate insecticide. It has been almost entirely banned for residential use since 2000 because of the heath risks it presents for children. But the pesticide's residue is still persistent in the environment. In addition, it is still sprayed commercially on some agricultural crops, including fruit trees and vegetables, and is also used on golf courses and for mosquito control.

毒死蜱是一种有机磷杀虫剂。自2000年以来，由于它给儿童带来的健康风险，几乎完全禁止在住宅使用。但农药残留在环境中仍然存在。此外，它还被商业地喷洒在一些农作物上，包括果树和蔬菜，还被用于高尔夫球场和蚊虫控制。

There has been a back-and-forth through the years as the government has struggled whether to keep the pesticide legal. The Obama administration's EPA banned it in 2015 and then the Trump administration EPA reversed that decision in 2017.

多年来，政府一直在为是否让这种农药合法而斗争。2015年，奥巴马政府的环保局禁止使用该物质，2017年，特朗普政府的环保局撤销了这一决定。

Since then, a dozen environmental groups petitioned the EPA to ban the pesticide and a federal judge ordered the agency in August 2018 "to revoke all tolerances and cancel all registrations for chlorpyrifos within 60 days." But the EPA just announced that it will not ban chlorpyrifos, CNN reports.

自那以后，十几家环保组织向美国环保署请愿，要求禁止使用这种杀虫剂。2018年8月，一名联邦法官命令该机构“在60天内撤销所有毒死蜱的抗药性，并取消所有登记。”但据CNN报道，美国环保署刚刚宣布不会禁止毒死蜱。

"EPA has determined that their objections must be denied because the data available are not sufficiently valid, complete or reliable to meet petitioners' burden to present evidence demonstrating that the tolerances are not safe," the agency said in a statement.

环保署在一份声明中说:“环保署已经决定，必须驳回他们的反对意见，因为现有的数据不够有效、完整或可靠，不足以满足请愿者提出证据证明耐受量不安全的要求。”

Environmental groups have argued that studies show that exposures to the pesticide is liked to low birth weight, reduced IQ, attention disorders and other issues in infants and children.

环保组织认为，研究表明，婴儿和儿童接触杀虫剂会导致出生体重低、智商降低、注意力紊乱和其他问题。
