为了探讨有机氯农药对缢蛏的食用安全性影响,2010年在宁波近岸海域采集了11个缢蛏样品用气相色谱法测定其持久性有机氯农药(8种)的残留量,采用接触风险指数法及致癌风险指数法进行了风险评估以及安全消费量的估算.由于我国《食品中农... 为了探讨有机氯农药对缢蛏的食用安全性影响,2010年在宁波近岸海域采集了11个缢蛏样品用气相色谱法测定其持久性有机氯农药(8种)的残留量,采用接触风险指数法及致癌风险指数法进行了风险评估以及安全消费量的估算.由于我国《食品中农药最大残留限量标准》和《海洋生物质量》中只对HCHs和DDTs总量进行限值,未对各分量进行具体限值,采用澳大利亚食品卫生标准值对部分单体进行评价.结果显示:缢蛏中α-HCH、β-HCH、γ-HCH、pp'-DDE、pp'-DDD、pp'-DDT的残留量均低于澳大利亚食品安全限量,HCHs和DDTs残留量符合我国《海洋生物质量》一类标准;致癌风险指数CRI在1.61×10-5~9.98×10-5;接触风险指数ERI在0.00~2.55×10-2;每天每千克人体食用缢蛏可接受的最高致癌安全消费量(按CRI≤10-4估算)平均为0.044 kg/(kg·d);每人每千克体重可接受的最高接触安全消费量(按ERI≤1估算)平均为0.502 kg/(kg·d).消费者在正常情况下食用宁波近岸海域的缢蛏而受到有机氯农药危害的可能性不大. 展开更多

This article research the food quality standards covered global and international regulations on food safety and quality, and public and private standards. The effect of global character of food safety and quality standardization shows that the important effect is increasing marginal costs of certification and accreditation, which puts pressure on export company profits in different countries. Main conclusions yield insights into the key following points: Increased food safety has been associated with higher income. Consumers and governments can afford to focus more on reducing food-borne safety risks once basic quantity needs for foods have been met or are in the process of being met. This suggests that policies focused on increasing income are the surest path to improving food safety in all countries. Food safety regulations should be designed to meet the food safety demands of consumers in rich countries and, at the same time, further the interests of both consumers and producers in poor countries. 展开更多
