食品中环境污染物多溴联苯醚的风险评估

Risk Assessment of Polybrominated Diphenyl Ethers( PBDEs) in Food in Chinese Urban Area

目的初步对我国某大型城市居民普遍摄入的食品中环境污染物多溴联苯醚(PBDEs)开展暴露风险评估。方法依据某大型城市食品中多溴联苯醚检测结果和2002年中国居民营养与健康状况调查中的大城市居民食物摄入量结果,按照风险评估的步骤对食品中多溴联苯醚进行危害识别、危害特征描述、暴露评估和风险特征描述。结果该市食品中污染物PBDEs远低于风险控制标准。结论由于多溴联苯醚对人体危害严重,且具有脂溶性、持久性、生物富集性特点,应尽快实施全国性、多角度的监测如食品、土壤、水质的监测,尽早防控其危害风险。

Objectives To assess the risk of polybrominated diphenyl ethers( PBDEs) in food in an urban area of China. Methods On the basis of food detection data of PBDEs and the food intake of urban residents based on the national survey of nutrition and health of chinese people conducted in 2002,the hazard identification,hazard characterization,exposure assessment and risk characteristics for PBDEs were evaluated according to the risk assessment process. Results The contamination of PBDEs in food in this city is lower than the standard limits for risk control. Conclusions Since the serious toxicity of PBDEs to human,more scientific and accurate risk assessment should be carried out; the national and multi-angle monitoring,such as food,soil and water,should be launched as soon as possible.
