Metals and pesticides pose risk to human health if accumulated in date fruits eaten for their distinctive sweetness and beneficial minerals. The present study evaluated the concentrations of metals and pesticides in Mazafati date fruit, soil, and irrigation water from three locations of Kerman province in Iran to show potential pollution hazards to consumers of date fruit in Iran. Levels of pesticides and metals were measured using chromatography-mass spectrometry (GC-MS) and atomic absorption spectrophotometry, respectively. The significant difference between the levels of Cu, Fe, chlorpyrifos, and malathion from three various locations was identified. The majority of metals except for Pb and Cd did not meet the safety limits concerning maximum allowable levels (MAL) in the Mazafati date cultivar. Estimated daily intake (EDI) of metals through date consumption (g/person/day) for all metals was above the tolerable daily intake in all studied locations. Furthermore, the concentrations of identified residues of chlorpyrifos, HCH total, and malathion are considerably upper than the maximum residue limits (MRL), showing a risky trend in the cultivation of date palm. As a result, the public consciousness of Iranian farmers should be raised to use pesticides more prudently. Also, consuming date fruits cultivated close to the industrial zones is hazardous and must be prevented.
