【摘要】：铜是人体必需的微量元素之一,但其过量摄入可能对人体健康带来潜在危害。为研究江西省乐安河流域铜矿开采区附近城市居民膳食铜暴露量及其健康风险的特征,在乐安河流域的上、中、下游选择3个典型城区(德兴市、乐平市和鄱阳县),分别采集蔬菜、大米、肉类、鱼、蛋和牛奶共6类食物(蔬菜、大米、肉类、鱼、蛋和牛奶)样品66份。利用电感耦合等离子体质谱仪测定食品的铜含量,并根据居民膳食结构特征,以危害指数为评价指标评估3个典型地区的儿童、青少年、成年人、老年人由铜摄入导致的非致癌风险。结果表明,6类食物中铜含量分别为(4.40±2.23)、(2.61±1.13)、(0.48±0.21)、(0.74±0.26)、(0.80±0.09)、(0.05±0.02)mg?kg~(-1)。蔬菜和大米中铜含量远高于肉类、鱼、蛋和牛奶,两者对人群的膳食铜摄入量贡献之和占总体的90%以上。3个研究城区膳食铜摄入量顺序为德兴乐平鄱阳。乐安河流域城市人群膳食铜摄入导致的非致癌风险大于1的比例顺序为儿童(68.8%)青少年(38.6%)成年人(16.9%)老年人(12.3%),其中,德兴市区儿童HQ1的比例为78.0%,乐平为69.0%,鄱阳为59.4%。表明该流域低年龄人群的铜暴露值得重点关注。本研究根据膳食结构全面考虑多种食物类型对膳食铜摄入的贡献,并将研究人群按年龄划分不同年龄段,分别进行健康风险评价。研究结果对居民健康饮食和政策制定具有一定参考意义。
[Abstract]:Copper is one of the essential trace elements in human body, but its excessive intake may bring potential harm to human health. In order to study the characteristics of dietary copper exposure and health risk of urban residents near the mining area of copper mine in the Loanhe Basin of Jiangxi Province, three typical urban areas (Dexing City, Dexing City) were selected in the upper, middle and lower reaches of Le'an River Basin. 66 samples of vegetables, rice, meat, fish, eggs and milk (vegetables, rice, meat, fish, eggs and milk) were collected in Leping and Poyang counties. The copper content in food was determined by inductively coupled plasma mass spectrometer (ICP-MS). According to the characteristics of dietary structure of residents, the hazard index was used to evaluate the children, adolescents and adults in three typical areas. The non-carcinogenic risk of copper intake in the elderly. The results showed that the contents of copper in the six kinds of foods were (4.40 卤2.23), (2.61 卤1.13), (0.48 卤0.21), (0.74 卤0.26), (0.80 卤0.09), (0.05 卤0.02) mg?kg~ (-1), respectively. The copper content in vegetables and rice was much higher than that in meat, fish, eggs and milk, which contributed more than 90% to the total dietary copper intake of the population. The order of dietary copper intake in the three urban areas was Dexing Leping Poyang. The proportion of non-carcinogenic risk caused by dietary copper intake in urban population of Le'an River was more than 1 in the following order: children (68.8%), adolescents (38.6%), adults (16.93.6%) and the elderly (12.3%). Among them, the proportion of HQ1 in children in Dexing city was 78.0, Leping was 69.0, and Poyang was 59.4%. The results indicate that copper exposure in the low age population of the basin deserves more attention. In this study, the contribution of various food types to dietary copper intake was comprehensively considered according to the dietary structure, and the health risk was evaluated according to age groups. The results of the study have certain reference significance for healthy diet and policy making of residents.
