    科學(xué)家評(píng)估歐洲兒童的長(zhǎng)期鉛膳食暴露情況
    日期:2012-11-20  來(lái)源:食品伙伴網(wǎng)

        食品伙伴網(wǎng)據(jù)外媒報(bào)道,9月份《食品添加劑污染物》(Food Additives & Contaminant)雜志刊登了一項(xiàng)評(píng)估歐洲兒童長(zhǎng)期膳食暴露情況的文章。

        在本次研究中,研究人員根據(jù)食品種類(lèi)對(duì)歐盟11國(guó)食品消費(fèi)數(shù)據(jù)分類(lèi),將該數(shù)據(jù)與不同成員國(guó)(約為所有歐盟國(guó)家)的鉛記錄數(shù)據(jù)綜合計(jì)算,得到歐盟兒童鉛長(zhǎng)期膳食暴露數(shù)據(jù)。

        部分原文報(bào)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.
