【摘要】：目的了解广西南丹县矿区周边常住居民主要食品中锑(Sb)的污染水平,评估矿业活动影响区居民膳食中Sb暴露安全性。方法于2013年7—8月和2014年11—12月,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痕量元素Sb的每日摄入量进行调查和测算,获得居民膳食中Sb暴露量,采用世界卫生组织(WHO)规定的Sb每日耐受摄入量(TDI值)来评价居民通过膳食摄入Sb的安全性健康风险。结果所采集14类食品共864份样品中,Sb检出率为97.2%,食品中Sb含量的范围、中位数及几何平均值分别为未检出~1.750、0.007和0.008μg/g。对照区和矿业影响区居民对Sb的膳食平均摄入量均低于TDI值(6μg/kg),肉类是膳食中Sb暴露的主要来源,其平均贡献率分别为64.4%和61.2%。锑暴露对人体的健康风险评估结果表明,对照区和矿业影响区居民通过膳食途径摄入的Sb无健康风险,但矿业影响区的潜在健康风险高于对照区,对男性的潜在健康风险高于女性。结论南丹县矿区周边居民膳食中Sb暴露水平总体处于安全水平,但膳食中肉类对Sb暴露的贡献较大。
[Abstract]:Objective to investigate the contamination level of SB in the main food of residents living around the mining area in Nandan County, Guangxi, and to evaluate the safety of SB exposure in diet of the residents in the mining area affected by mining activities. Methods from July to August on 2013 and from November to December on 2014, the safety of SB exposure in diet was evaluated. The daily intake of trace element SB in the diet of the residents in the mining affected area and the control area was investigated and measured by weighing and chemical analysis, and the amount of SB exposure in the diet of the residents was obtained. The daily tolerance intake of SB (TDI value) was used to evaluate the safety and health risk of residents taking SB through diet. Results the detection rate of SB in 864 samples of 14 kinds of food was 97.2%, and the range of SB content in food was obtained. The median and geometric mean values were 1.750 渭 g / g and 0.008 渭 g / g, respectively. The average dietary intake of SB in control area and mining affected area was lower than TDI value of 6 渭 g / kg. Meat was the main source of SB exposure in diet. The average contribution rates were 64.4% and 61.2 respectively. The results of health risk assessment showed that there was no health risk of SB intake by residents in control area and mining affected area, but the potential health risk in mining affected area was higher than that in control area. Conclusion the level of SB exposure in diet of residents in the mining area of Nandan County is generally safe, but the contribution of meat in diet to SB exposure is greater.
