本研究旨在估算中国厦门居民膳食中镉 (Cd)、铅 (Pb)、汞 (Hg)（总量和甲基）和砷 (As) 的摄入量。对2005年至2009年在厦门市5个区随机采集的蔬菜、水果、肉类和海鲜样品中这些有毒元素（TE）的浓度进行了测定，并评估了厦门居民因膳食摄入而产生的健康风险。个别元素的目标危害商（THQ）值远低于1，表明在当前食品消费率下，厦门居民的TEs非致癌风险极小。然而，由于第 95 个百分位数的 HI 高于 1，食用整个食品可能会导致潜在的健康风险。Cd、Pb、Hg T 和 As 对 HI 的平均暴露水平的相对贡献分别为 16.0%、15.9%、5.9% 和 62.2%，对平均暴露水平的相对贡献分别为 13.3%、13.4%、5.6% 和 67.9%。第 95 个百分位数估计值。头足类食物摄入的甲基汞THQ值小于1。番茄、头足类、茄子、卷心菜、柑橘和猪肉是TEs膳食总摄入量的主要来源。致癌风险评估显示，砷的致癌率超过了公认的风险水平10(-4)。因此，砷对厦门居民的致癌风险值得关注。
This study was designed to estimate the dietary intake of cadmium (Cd), lead (Pb), mercury (Hg) (total and methyl), and arsenic (As) by inhabitants of Xiamen, China. The concentrations of these toxic elements (TEs) were determined in vegetables, fruits, meat, and seafood samples randomly acquired in 5 districts of Xiamen between 2005 and 2009. Health risks were evaluated for inhabitants of Xiamen due to dietary consumption. The target hazard quotient (THQ) values for individual elements were far below 1, indicating minimal noncarcinogenic risks from TEs for inhabitants of Xiamen under the current food consumption rate. However, consumption of the entire foodstuffs could lead to potential health risks since the 95th percentile HI was higher than 1. The relative contributions of Cd, Pb, Hg T, and As to the HI were 16.0%, 15.9%, 5.9%, and 62.2% for the mean exposure level, and 13.3%, 13.4%, 5.6%, and 67.9% for the 95th percentile estimate. The THQ value of methyl mercury through consumption of cephalopod was less than 1. Tomato, cephalopod, eggplant, cabbage, orange, and pork were the main sources of total dietary intakes of TEs. The estimation of carcinogenic risk shows that the carcinogenic rate of arsenic exceeded the accepted risk level of 10(-4). Therefore, the carcinogenic risk of arsenic for inhabitants of Xiamen is of concern.
