水产品来源的甲醛膳食暴露评估初步研究

应用MonteCarlo模拟技术定量评估我国人群通过食用水产品途径的甲醛膳食暴露状况。结果表明,我国城乡普通居民通过食用水产品途径的甲醛暴露水平较低,且通过食用水产品途径城市人群摄入甲醛面临的健康风险高于农村人群;不同年龄群体的膳食暴露量存在差异,幼年消费者(2～13岁)的暴露量均高于成年人;7岁前,女孩的暴露水平高于男孩,7岁后,男孩的暴露水平高于女孩。我国普通居民仅通过食用水产品途径摄入甲醛对人体健康状况造成风险的可能性不大,但是幼儿、儿童是食用水产品途径甲醛暴露的敏感性群体,应在后续的风险管理过程中应给予足够的关注和重视。

Primary study on exposure assessment of formaldehyde in fishery products

The quantitative exposure assessment of formaldehyde by means of fishery products’dietary consumption was conducted with application of Monte Carlo simulation techniques.The results showed that urban and rural ordinary residents in China had low levels of formaldehyde dietary exposure by eating fishery products.But the urban population faced more serious health risks of formaldehyde exposure than rural population by means of fishery products’consumption.Different age groups had great differences in dietary exposure of formaldehyde from fishery products.The exposure level of 2～13 age groups was higher than the adults’.Exposure risk faced by girls under the age of 7 was higher than the boys at the same age,and the exposure level reversed for the subpopulation at the age above 7.Therefore,to the general population,the dietary exposure of formaldehyde only by fishery products’consumption was unlikely to bring about severe human health risks.To reduce the formaldehyde exposure from fishery products,the infant and children should be the main populations to be given sufficient concern and attention in the subsequent risk management process.
