摘要
化学污染物是影响全球食品安全和危害人体健康的主要因素之一。对食品中化学污染物进行风险评估是保障食品安全、促进食品贸易和健全食品安全体系的重要手段。本文简要介绍了化学污染物风险评估的内容和基本方法,对国外化学污染物风险评估开展情况进行了概述,重点对国内开展的食品中化学污染物风险评估的研究进展进行综述,包括重金属、有机污染物、农药残留、黄曲霉毒素等,并对国内开展食品中化学污染物风险评估的方法进行了分析比较。重金属、农药残留和黄曲霉毒素方面的评估结果均表明:儿童的膳食暴露量偏高,需引起重视。此外提出目前我国食品中化学污染物风险评估中存在的主要问题和建议,为进一步开展化学污染物风险评估提供借鉴。
ABSTRACT:Chemical contaminants are of immediate and serious concern to food safety and human health. Risk assessment for chemical contaminants in food not only protects food safety and human health, but also enhances consumer protection and facilitates international trade. Conceptions, classification and methods ap-plication on chemical risk assessment were introduced in this paper. The risk assessment of chemical contami-nants in foreign countries was summarized, and progress in research of chemical contaminants risk assessment in food at home was reviewed in detail, including heavy metals, organic pollutants, pesticides, and aflatoxin etc. The methods of these risk assessment were analyzed and compared. The assessment results of heavy metal, pesticide residues and aflatoxin showed that:children's dietary exposure is high. Main problems in chemical risk assessment in China at present were pointed out and advices were given on further complete chemical risk assessment.
