2016年7月20日美國(guó)聯(lián)邦公報(bào)發(fā)布通告，豁免一種農(nóng)藥助劑的最大殘留限量。

　　該種農(nóng)藥助劑為2-丙烯酸，丁酯，乙酸乙烯酯鈉鹽聚合物（2-propenoic acid, butyl ester, polymer with ethenyl acetate and sodium ethenesulfonate）。本次申請(qǐng)由Celanese Ltd 公司提交。美國(guó)環(huán)保署經(jīng)評(píng)估，認(rèn)為沒(méi)必要制定食品與飼料中有關(guān)的限量。

　　部分原文報(bào)道如下：

　　This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, butyl ester, polymer with ethenyl acetate and sodium ethenesulfonate （CAS Reg. No. 66573-43-1） when used as an inert ingredient in a pesticide chemical formulation. Celanese Ltd submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of 2-propenoic acid, butyl ester, polymer with ethenyl acetate and sodium ethenesulfonate on food or feed commodities.
