据美国联邦公报消息，7月5日美国环保署发布通告，豁免二氧化钛(Titanium Dioxide)作为农药助剂(0.1%，按重量计)用于控制蜂巢雅氏瓦螨时的最大残留限量。
本次豁免申请由拜耳保健公司提交。美国环保署经评估，按照本次用途没必要制定其最大残留限量。
部分原文报道如下：
This regulation establishes an exemption from the requirement of a tolerance for residues of titanium dioxide(CAS Reg. No. 13463-67-7)in honey when used as an inert ingredient(colorant)at a concentration of not more than 0.1% by weight in pesticide formulations intended for varroa mite control around bee hives. Bayer Healthcare, LLC submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act(FFDCA)，requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of titanium dioxide resulting from this use.
