PURPOSE
The presence of toxic heavy metals (HMs) in agricultural crops can be considered as a noteworthy threat for consumers. The aim of this study was to assess the content of HMs (Pb, As, Cr, Cd, Co, Hg, and Ag) and their potential health risk in summer crops and vegetables (watermelon, cantaloupe, cucumber, melon, tomato, onion, potato, raw and stewed vegetables) in Ilam province, Iran.
METHODS
Totally, 31 crop samples were collected from local farms during the 2019 harvest season and the elements content were evaluated using inductively coupled plasma-mass spectrometry (ICP-MS). The non-carcinogenic health risk of HMs to the adults and children was estimated by Monte Carlo simulation method and target hazard quotients (THQs).
RESULTS
In general, the results showed that the concentration of Cr in the studied agricultural crops was higher than other HMs. As well as, the carcinogenic risk (CR) obtained for adults and children were more than the acceptable range for As. Also, CR for As in raw vegetable was the most (8.19E-1) and violated the threshold risk limit. The total carcinogenic risk of HMs in children was higher than that in adults.
CONCLUSION
These results suggest that the agricultural crops were not safe for human consumption with potential risks associated. Due to the possible health effects of such products consumption, proper action should be taken to avoid chronic exposure, prevention of further pollution and consequent adverse health implications.
目的
农作物中有毒重金属的存在可被视为对消费者的重大威胁。本研究的目的是评估伊朗伊拉姆省夏季作物和蔬菜（西瓜、哈密瓜、黄瓜、甜瓜、番茄、洋葱、土豆、生蔬菜和炖菜）中重金属（铅、砷、铬、镉、钴、汞和银）的含量及其潜在健康风险。
方法
在2019年收获季节从当地农场总共采集了31个作物样本，并使用电感耦合等离子体质谱法（ICP-MS）评估元素含量。通过蒙特卡罗模拟方法和目标危害商数（THQs）估计重金属对成人和儿童的非致癌健康风险。
结果
总体而言，结果表明，所研究农作物中铬的浓度高于其他重金属。此外，成人和儿童的致癌风险（CR）超过了砷的可接受范围。生蔬菜中砷的致癌风险最高（8.19E-1），超过了阈值风险限值。儿童中重金属的总致癌风险高于成人。
结论
这些结果表明，这些农作物对人类消费不安全，存在潜在风险。由于食用此类产品可能对健康产生影响，应采取适当行动避免长期接触，防止进一步污染以及随之而来的不良健康影响。
