进行了一项食品调查，目的是调查在阿尔及利亚销售的各种水果和蔬菜中的铅（Pb）、锌（Zn）、铜（Cu）和铬（Cr）含量。浓度（毫克/千克干重）在选定的食品中，Cu、Zn、Pb和Cr的检出范围分别为4-29.49、11.17-49、12.33-3933和3-16.33。在市场出口处随机抽取843人，采用自填式问卷调查所选项目的食物摄入率。通过估算每种重金属的每日摄入量（EDI）和目标危害商数（THQ），对消费者的潜在健康风险进行了调查。对于所有食品，铜、锌和铬的EDI和THQ均低于阈值，而铅的EDI和THQ则超过阈值（EDI：15.66微克铅/千克体重/天; THQ：4.37），这表明在一生的接触时间内存在明显的健康风险。(C)2014爱思唯尔有限公司版权所有。
A food survey was carried out with the aim to investigate the levels of lead (Pb), zinc (Zn), copper (Cu) and chromium (Cr) in various fruits and vegetables sold in Algeria. Concentrations (mg/kg dry wt.) in selected foodstuffs were detected within the following ranges: 4-29.49, 11.17-49, 12.33-3933 and 3-16.33 for Cu, Zn, Pb and Cr respectively. The food ingestion rate of the selected items was investigated by self-administered questionnaires which were filled by a total of 843 people randomly recruited at the exit of markets. The potential health risk for consumers was investigated by estimating the daily intake (EDI) and the target hazard quotient (THQ) for each heavy metal. For all foodstuffs, the EDI and the THQ were below the threshold values for Cu, Zn and Cr while they exceeded the thresholds for Pb (EDI: 15.66 mu g Pb/kg body weight/day; THQ: 4.37), indicating an obvious health risk over a life time of exposure.
