摘　　要：【目的】针对辽宁省苹果、梨、桃和葡萄4种主要水果开展矿质元素含量及其风险评估研究,明确主要矿质元素含量水平及其对消费者健康的暴露水平,为水果生产和消费提供科学依据。【方法】从主产区(大连、鞍山、营口、锦州、朝阳、葫芦岛和绥中)共采集包括苹果、梨、桃和葡萄在内的140个样品,采用电感耦合等离子体发射光谱仪测定10种矿质元素含量,应用SPSS17.0数据处理软件对不同矿质元素含量水平及相关性进行分析;并分别以日推荐摄入量(RNI)或适宜摄入量(AI)和可耐受最高摄入量(UL)为评价标准,对不同年龄段人群每日从4种水果中摄入矿质元素的量进行分析和暴露评估;再结合居民平衡膳食宝塔和食物成分表,进行成人全膳食风险评估。【结果】10种矿质元素的平均含量由高到低依次为:K(367.68 mg·kg^(-1))>P(122.65 mg·kg^(-1))>Mg(78.93 mg·kg^(-1))>Ca(76.36 mg·kg^(-1))>Na(12.37 mg·kg^(-1))>B(3.03 mg·kg^(-1))>Fe(2.86 mg·kg^(-1))>Cu(1.17 mg·kg^(-1))>Mn(1.02 mg·kg^(-1))>Zn(0.82 mg·kg^(-1)),变异系数范围为27.80%(Mg)—82.05%(Cu);4种水果的K和Mg之间均呈极显著正相关,所测10种矿质元素之间的相关性以正相关为主;不同年龄组人群从4种水果中摄入的矿质元素的量占其RNI或AI的比值分析表明,K元素的比值根据年龄段由低到高呈下降趋势,其余元素按照年龄段变化呈现降-升-降的趋势。Fe最大比值位于4—7岁年龄段,比值为6.54%,其余元素均在2—4岁年龄段比值最高,其中Cu高达83.30%,Mg达11.01%,P、K、Zn、Ca、Na依次为8.57%、8.43%、4.25%、2.46%和0.39%。来自4种水果的膳食风险评估结果表明,Cu元素在2—4岁人群中的平均风险指数和最大风险指数分别为12.50%和37.02%,除Cu以外,来自4种水果的矿质元素摄入风险指数均很低,风险指数远小于100%,风险指数的范围为0.33%(Zn)—13.40%(Mn);用UL为评价标准计算成人全膳食风险,风�[Objective] A study of detection and dietary exposure assessment of main mineral element contents of 4 dominant fruits from Liaoning province （including apple, pear, grape and peach） was carried out for the purpose of providing references to fruit production and consumptions. [Method] A total of 140 samples of the 4 fruits were collected from the main producing areas,including Dalian, Anshan, Yingkou, Jinzhou, Chaoyang, Huludao and Suizhong. The contents of 10 mineral elements were detected by ICP-AES and the correlation was analyzed by SPSS 17.0 statistic software. Daily intake assessments of mineral elements from the 4 fruits among different populations were conducted and analyzed using recommended nutrient intake （RNI） or adequate intake （M） and tolerable upper intake level （UL）, respectively. Total diet risk assessment for adult was analyzed with residents balanced diet pagoda and food composition table. [Result] The average contents of 10 mineral elements were followed by the order of K （367.68 mg·kg^-1）〉P （122.65 mg·kg^-1）〉Mg （78.93 mg·kg^-1）〉Ca （76.36 mg·kg^-1） 〉Na （ 12.37 mg·kg^-1） 〉B （3.03 mg·kg^-1） 〉Fe （2.86 mg·kg^-1） 〉Cu （ 1.17 mg·kg^-1） 〉Mn （ 1.02 mg·kg^-1） 〉Zn （0.82 mg·kg^-1） and the range of coefficient of variation was from 27.80% （Mg） to 82.05% （Cu） . There was a significant correlation between K and Mg. Along with the growth of the age, the ratios of K to its AI was declined while other elements were showed down-up-down. The maximal ratio of Fe was 6.54% found in 4-7 ages and other elements were in 2-4 ages. In which, the percentages ofRNI ofCu, Mg, P, K, Zn, Ca and Na were 83.30%, 11.01%, 8.57%, 8.43%, 4.25%, 2.46% and 0.39%, respectively. Results of dietary risk assessment showed that the average and the highest risk index of Cu in 2-4 ages were 12.50% and 37.02%, respectively. The risk indexes of other mineral elements were all far below 100% with the range of 0.33% （Zn） -13.40% （Mn） . Risk ind
