科学家评估欧洲儿童的长期铅膳食暴露情况

    食品伙伴网讯 据外媒报道，9月份《食品添加剂与污染物》（Food Additives & Contaminant）杂志刊登了一项评估欧洲儿童长期铅膳食暴露情况的文章。

    在本次研究中，研究人员根据食品种类对欧盟11国食品消费数据分类，将该数据与不同成员国（约为所有欧盟国家）的铅记录数据综合计算，得到欧盟儿童铅长期膳食暴露数据。

    部分原文报道如下：

    Long-term dietary exposures to lead in young children were calculated by combining food consumption data of 11 European countries categorised using harmonised broad food categories with occurrence data on lead from different Member States （pan-European approach）。 The results of the assessment in children living in the Netherlands were compared with a long-term lead intake assessment in the same group using Dutch lead concentration data and linking the consumption and concentration data at the highest possible level of detail. Exposures obtained with the pan-European approach were higher than the national exposure calculations. For both assessments cereals contributed most to the exposure. The lower dietary exposure in the national study was due to the use of lower lead concentrations and a more optimal linkage of food consumption and concentration data.

     When a pan-European approach, using a harmonised food categorisation system and "European" concentration data, results in a possible health risk related to the intake of an environmental chemical for a certain country, it is advisable to refine this assessment, as part of a tiered approach, using national occurrence data, including an optimised linkage between foods analysed and consumed for that country. In the case of lack of occurrence data, these data can be supplemented with data from the "European" concentration database or by generating additional concentration data at country level.
