目的:对武汉市居民通过膳食摄入的镉对本市居民健康所带来的风险进行评价。方法:对武汉市市售食品进行随机抽样,采用国家标准方法对其中的镉含量进行测定,结合卫生部2002年膳食结构调查的资料,用美国环境保护局的健康风险评价模型对武汉市总膳食中的镉所带来的健康风险进行定量评价。结果:武汉市成人居民通过食物摄入的平均镉量约12微克,由之带来的年均超额风险度约1.70×10-5a-1。结论:武汉市总膳食中镉所带来的平均健康风险总体上处于可接受水平,但其概率分布特征有待于进一步研究;提高鱼类食品的摄入代替一部分肉类食品有助于减小镉的摄入。
OBJECTIVE: To evaluate the health risk caused by cadmium intake of Wuhan residents through dietary intake of cadmium. Methods: The samples of commercially available foods in Wuhan City were randomly sampled and the cadmium content was determined by the national standard method. Combined with the data of the Ministry of Health in 2002 on the survey of dietary structure, the health risk evaluation model of the US Environmental Protection Agency In the health risks posed by cadmium quantitative evaluation. Results: The average cadmium intake of adult residents in Wuhan through food was about 12 micrograms, resulting in an average annual excess risk of about 1.70 × 10-5 a-1. Conclusion: The average health risk of total cadmium in Wuhan is generally acceptable, but its probability distribution needs to be further studied. Increasing the intake of fish food instead of some meat foods will help to reduce cadmium Intake.
