食品伙伴網(wǎng)訊    據(jù)美國(guó)聯(lián)邦公報(bào)消息，5月19日美國(guó)環(huán)保署發(fā)布通告，豁免順丁烯二酸酐（maleic anhydride ）的最大殘留限量。

　　本次限量修訂申請(qǐng)由Exponent代表Cheminova A/S公司提出。美國(guó)環(huán)保署認(rèn)為，當(dāng)順丁烯二酸酐按照不超過(guò)3.5%（重量計(jì)）比例作為農(nóng)藥成分用于作物時(shí)，豁免最大殘留限量要求。

　　部分原文報(bào)道如下：

　　This regulation establishes an exemption from the requirement of a tolerance for residues of maleic anhydride （CAS Reg. No. 108-31-6） when used as an inert ingredient （stabilizer） in pesticide formulations applied to growing crops at a maximum concentration not to exceed 3.5% by weight in the pesticide formulation. Exponent, on behalf of Cheminova A/S, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting an amendment to an existing requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of maleic anhydride.
