Abstract

The current study aims to investigate the levels of the toxic metal in agricultural products (legumes, wheat, and potato) collected in Markazi province, Iran, and human health risk by using inductively coupled plasma - optical emission spectrometry (ICP-OES). The levels of arsenic (As) and cadmium (Cd) in all samples were lower than the limit of detection (LOD), while the level of Cd in potato samples was lower than the maximum permisible level (MPL) of the European commission (EC). The non-carcinogenic and carcinogenic risk assessment by direct ingestion of agricultural products was calculated using the United States Environmental Protection Agency (USEPA) method. The highest mean of toxic metals was observed for lead (Pb) in legume samples (562.17 μg kg− 1). Mercury (Hg) and Pb levels in all samples were higher than LOD, while Pb level in wheat samples were lower than of EC. The rank order of Hg and Pb levels in all samples based on target hazard quotient (THQ) value was wheat> potato>legume. The THQ index of Hg and Pb by the deterministic method in wheat was 1.37 and 0.454; in potato 0.139 and 0.104; in legume 0.092 and 0.41, respectively. The carcinogenic risk index was at an acceptable range. The high hazard index values were estimated and the THQ index for Hg in wheat suggests a non-negligible health risk. © 2021, The Author(s).
