摘要
通过调查南丹矿业影响区和对照区常住居民食品中锌(Zn)的含量,评估南丹县矿区居民锌膳食暴露及健康风险。在2013年7—8月和2014年11—12月期间,采用称重法和化学分析法对矿业影响区和对照区居民膳食Zn的每日摄入量调查,获得居民膳食中Zn暴露量,并采用美国环保署(US EPA)推荐的方法计算人体中锌的长期日摄入量,得出该元素的长期暴露量(CDI),评估居民通过膳食摄入Zn的健康风险。矿业影响区与对照区膳食锌含量显著差异(p<0.05)。矿业影响区和对照区居民经食品摄入Zn的量分别为10.446和5.647 mg/d。矿业影响区男女Zn潜在非致癌风险健康影响危险系数HQ值均小于1。南丹矿区居民膳食Zn摄入不足,潜在非致癌风险较低,应加强营养知识宣教补充膳食锌。
To understand the content of zinc(Zn) in the daily food of permanent residents around the mining area of Nandan, and to evaluate the safety of Zn exposure in residents diet affected by mining activities from July to August 2013 and from November to December 2014, the daily intake of Zn in residents diet in affected areas and control areas was investigated and measured by weighing method and chemical analysis method. Zn exposure in residents diets was obtained by US EPA recommended method to characterize the daily exposure of zinc and to characterize long-term exposure(CDI).The potential non-carcinogenic health risks of residents was assessed through dietary Zn intake. There were significant differences between zinc in dietary and other cereals and control areas(p<0.05). In the mining affected areas, the daily intake of Zn from foods was 10.446 and 5.647 mg/d. The HQ values of men and women in the affected mining area were low than 1. The potential non-cancer risk of dietary Zn among residents in the affected areas of Nandan was lower. Insufficient intake is low. Nutrition knowledge should be strengthened to supplement dietary zinc.
