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.
