法国消费者在密闭容器微波消化和电感耦合等离子体质谱定量后，通过从餐饮机构购买的双餐(早餐和午餐)，对21种必需和非必需矿物质元素的膳食暴露进行了估计。金属和矿物质的每日膳食摄入量估计值与粮农组织/世卫组织为估计毒性风险而制定的暂定每周允许摄入量(PTWI)、允许每日摄入量(TDI)或允许每日摄入量(ADI)，以及美国建议的每日摄入量(US RDA)或估计的安全适量每日摄入量(ESADDI)进行了比较。此外，还与以前的法国研究以及其他国家的研究结果进行了比较。估计的平均每日摄入量为：锂11克、钠3.42克、镁192毫克、铝2.03毫克、钾3.64克、钙642毫克、铬154克、铁12.3毫克、锰2.15毫克、钴4克、镍74克、铜925克、锌10.2毫克、砷147克、硒66克、钼112克、镉3.6克、锡2.32毫克、锑3克、汞9克和铅34克。对于非必需(有毒)元素，铝、锡、锑、镉、砷、汞和铅的每日估计摄入量远低于可接受的限度；个别矿物质和必需微量元素的每日摄入量估计值与其各自的PTWI、ADI、TDI、ESADDI和US RDA相近或略低，与其他国家的研究结果一致。并对多元素电感耦合等离子体质谱技术的性能进行了评价。
An estimation of the dietary exposure of French consumers to 21 essential and non-essential mineral elements using duplicate meals ( breakfast and lunch) purchased from catering establishments was investigated after digestion by a closed vessel microwave procedure and quanti cation by ICP-MS. Daily dietary exposure estimates for metals and minerals were compared with the Provisional Tolerable Weekly Intakes (PTWI), the Tolerable Daily Intake (TDI) or the Acceptable Daily Intakes (ADI), as established by the FAO/WHO to estimate the risk of toxicity, and the US Recommended Daily Allowances (US RDA) or the Estimate Safe & Adequate Daily Dietary Intakes (ESADDI). Moreover, comparisons were made with those from previous French studies as well as those from other countries. The estimated mean daily intakes were 11 g for lithium, 3.42 g for sodium, 192 mg for magnesium, 2.03 mg for aluminium, 3.64 g for potassium, 642 mg for calcium, 154 g for chromium, 12.3 mg for iron, 2.15 mg for manganese, 4 g for cobalt, 74 g for nickel, 925 g for copper, 10.2 mg for zinc, 147 g for arsenic, 66 g for selenium, 112 g for molybdenum, 3.6 g for cadmium, 2.32 mg for tin, 3 g for antimony, 9 g for mercury and 34 g for lead. For the non-essential ( toxic) elements, aluminium, tin, antimony, cadmium, arsenic, mercury and lead, the daily intake estimates were far below tolerable limits; and similar or somewhat lower than their respective PTWI, ADI, TDI, ESADDI and US RDA for individual minerals and essential trace elements, with good agreement with other country studies. The performance of the multi-elemental ICP-MS technique was also evaluated.
