研究了3~10岁儿童学校套餐中邻苯二甲酸二(2-乙基己基)酯(DEHP)和邻苯二甲酸二丁酯(DBP)的含量及包装工艺对膳食污染的影响，并估算了它们对每日摄入量的贡献。包装由聚乙烯涂层铝(PE/Al)碟片由聚乙烯对苯二甲酸乙二醇酯涂层铝箔(PET/Al)热焊接组成。加工前的食品也进行了分析。收集包装前和包装后的总膳食。研究发现，92%用于配餐的食品含有DEHP，其中76%的DBP含量达到可检测的水平。在包装前的熟食中，DEHP的中位浓度水平介乎每克湿重111.4至154.8毫微克，而二苯基苯的中位数则介乎每克湿重32.5至59.5毫微克。在盒装膳食中，DEHP的中位数为127.0至253.3 ng/g WW，DBP的中位数为44.1至80.5 ng/g WW。包装前和包装后熟食中DEHP浓度的中位数分别增加113%和125%。对于幼儿园和小学生，通过学校膳食摄入DEHP可使EFSA TDI平均增加18%和12%，DBP平均增加50%和30%。
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%.
