Packed school meals for children 3-10 years old were studied to evaluate the levels of di(2-ethylhexyl)phthalate (DEHP) and di-n-butylphthalate (DBP) and the influence of the packaging process on meal contamination, and their contribution to daily intake was estimated. The packaging consisted of polyethylene-coated aluminum (PE/Al) dishes thermally welded by a polyethyleneterephthalate-coated aluminum (PET/Al) foil. Foodstuffs before processing were analyzed, too. Total meals before packaging and after packaging were collected. It was found that 92% of foodstuffs employed in meal preparation contained DEHP, and 76% of them DBP, at detectable levels. In cooked foods before packaging the DEHP median concentration levels varied from 111.4 to 154.8 ng/g ww and those of DBP between 32.5 and 59.5 ng/g ww. In packed meals the DEHP median values ranged from 127.0 to 253.3 ng/g ww, and DBP median values varied from 44.1 to 80.5 ng/g ww. The mean increases of median concentrations of DEHP in cooked foods before and after packaging were 113 and 125% for DBP. For nursery and primary school children DEHP intake via school meals can raise on average the respective EFSA TDI by 18 and 12% and that of DBP by 50 and 30%.
研究了 3-10 岁儿童的包装学校餐，以评估邻苯二甲酸二（2-乙基己基）酯（DEHP）和邻苯二甲酸二丁酯（DBP）的水平，以及包装过程对餐食污染的影响，并估计其对日常摄入量的贡献。包装由聚乙烯涂铝（PE/Al）盘和聚对苯二甲酸乙二醇酯涂铝（PET/Al）箔热焊接而成。加工前的食品也进行了分析。收集了包装前和包装后的总餐食。结果发现，92%的餐食准备中使用的食品中含有可检测水平的 DEHP，76%的食品中含有 DBP。在包装前的熟食中，DEHP 的中值浓度范围为 111.4-154.8ng/g ww，DBP 的中值浓度范围为 32.5-59.5ng/g ww。包装后的餐食中，DEHP 的中值范围为 127.0-253.3ng/g ww，DBP 的中值范围为 44.1-80.5ng/g ww。包装前后熟食中 DEHP 中值浓度的平均增加量分别为 113%和 125%，DBP 分别为 50%和 30%。对于幼儿园和小学儿童，通过学校餐食摄入的 DEHP 平均可使各自的 EFSA TDI 分别增加 18%和 12%，DBP 增加 50%和 30%。
