氧化钨添加剂的平均氧化水平为2.86，对应的氧含量为19.93%、�/div>

欧盟食品安全局分别开展了迁移测试以及遗传毒性评估。欧盟食品安全局认为，按照最大使用量75 mg/kg，将氧化钨作为再热剂用于PET不存在安全问题。然而用作其他功能或用于其他聚合物时，迁移量不应超过50 ��g/kg（以钨计）、�/div>

This scientific opinion of EFSA Panel on Food Co ntact Materials, Enzymes, Flavourings and Processing Aids （CEF Panel� deals with the risk assessment of the additive tungsten oxide, CAS No 39318-18-8 and FCM No 1064, for use in food co ntact materials as a reheat agent in polyethylene terephthalate （PET� at a maximum use level of 75 ppm �?5 mg/kg PET）� The substance is a mixture of tungsten oxides with tungsten at different oxidative levels. The average oxidation level of tungsten in the oxides is 2.86 correspo nding to 19.93% oxygen content. Detailed information on impurities is provided as confidential. Specific migration from PET plaques with the substance at 150 mg/kg （double the maximum intended use level of 75 mg/kg� was determined into 95% ethanol, as a worst-case simulant for PET due to its swelling effect. Under these test conditions, the specific migration, measured as tungsten using ICP-MS, was at the level of 1 ��g/kg.
