Lead (Pb), arsenic (As), cadmium (Cd) and aluminum (Al) are the four most common heavy metals and can cause serious harm to human health. To evaluate contamination levels and associated safety issues of the four common heavy metals of the residents in Jilin Province, China, a total diet study (TDS) method was used. Concentration and consumption data of the four heavy metals were collected from the fifth Chinese TDS of Jilin province. In total, 12 food groups were studied and two regions were selected for comparison. According to the results, the mean concentration of lead, arsenic, cadmium, and aluminum was 0.0189, 0.0691, 0.0085, and 9.309 mg/kg, respectively. Aluminum in deep-fried dough sticks exceeded the national limit standard. Pollution of the Songhua River Basin is not very different from that of other areas. The average consumer exposure to the four heavy metals in the 2 to 6-year-old group was the highest among all age-groups. Potatoes and their products were the primary sources of dietary exposure to lead. Aquatic products and their related commodities had the highest contribution to arsenic exposure. Vegetables and vegetable products were the main sources of dietary exposure to cadmium. The highest contributor to aluminum in the diet was from cereals and cereal products. In general, there might be some potential risks to the 2 to 6-year-old population due to exposure to lead and aluminum. Contamination of aluminum in cereals and cereal products needs further consideration.
铅（Pb）、砷（As）、镉（Cd）和铝（Al）是四种最常见的重金属，会对人体健康造成严重危害。为评估中国吉林省居民这四种常见重金属的污染水平及相关安全问题，采用了全膳食研究（TDS）方法。四种重金属的浓度和消费数据取自吉林省第五次中国全膳食研究。总共研究了12个食物组，并选取了两个地区进行比较。结果显示，铅、砷、镉和铝的平均浓度分别为0.0189、0.0691、0.0085和9.309毫克/千克。油条中的铝超过了国家限量标准。松花江流域的污染与其他地区差别不大。2至6岁年龄组的消费者对这四种重金属的平均暴露量在所有年龄组中最高。土豆及其制品是膳食中铅暴露的主要来源。水产品及其相关商品对砷暴露的贡献最大。蔬菜及其制品是膳食中镉暴露的主要来源。膳食中铝的最大贡献来自谷物和谷物制品。总体而言，2至6岁人群因接触铅和铝可能存在一些潜在风险。谷物和谷物制品中铝的污染需要进一步关注。
