据美国联邦公报消息,5月19日加拿大环保署发布通告,豁免顺丁烯二酸酐(maleic anhydride )的最大残留限量。
本次限量修订申请由Exponent代表Cheminova A/S公司提出。美国环保署认为,当顺丁烯二酸酐按照不超过3.5%(重量计)比例作为农药成分用于作物时,豁免最大残留限量要求。
部分原文报道如下:
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.
