Abstract

Rapid urbanisation has increased heavy metal pollution. While vegetables are vital for health, rising metal contamination can pose significant risks that need attention. To evaluate the health risks of consuming vegetables for residents in Gansu Province, this study used ICP-MS to determine Pb and Cd content in 178 vegetable samples and to conduct risk assessments. The average levels of Pb and Cd in vegetables were 0.104 and 0.014 mg/kg, with Cd exceeding Chinese maximum limits in 8.4% of the samples. Deterministic assessment indicated that the hazard quotients (HQs) and hazard index (HI) of Pb and Cd were below 1. Probabilistic assessments were consistent. The carcinogenic risk (CR) of Pb in vegetables was below 10^-4. CR of Cd was above 10^-4 in 80.1% of males and 82.4% of females. Thus, Pb in vegetables did not pose a health risk, but Cd may pose a carcinogenic risk.

甘肃省商品蔬菜中铅、镉含量及健康风险评价

快速的城市化加剧了重金属污染。虽然蔬菜对健康至关重要，但不断上升的金属污染可能带来重大风险，需要引起注意。为评价甘肃省居民食用蔬菜的健康风险，本研究采用ICP-MS法测定了178份蔬菜样品中的Pb、Cd含量，并进行了风险评价。蔬菜中Pb和Cd的平均含量分别为0.104和0.014 mg/kg，其中Cd超标的样品占8.4%。确定性评价表明，Pb、Cd的危害商（HQs）和危害指数（HI）均小于1。概率评估是一致的。蔬菜中铅的致癌风险（CR）在10-4以下。80.1%的男性和82.4%的女性Cd的CR在10-4以上。因此，蔬菜中的铅不构成健康风险，但镉可能构成致癌风险。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
