Abstract
Date fruits have ample amount of beneficial minerals but owing to diverse causes may contract with heavy metals and contaminants during field, processing, or transportation posing health challenges to consumers. Hence, current research explored the toxic heavy metals (Al, As, Cr, Pb, Cd, and Sb) levels in seven date varieties (Sakay Mabroum, Sakay Normal, Rashadya Al-qaseem, Barny Al-Madina, Eklas Al-Hassa, Safawy Al-Madina, Kadary) collected from different locations of Saudi Arabia by applying inductively coupled plasma optical emission spectroscopy. Mean values of heavy metals were calculated and expressed. Most of the heavy metals with the exception of As, Pb, and Cd are within safe limit with respect to maximum allowable levels (MAL) in some date cultivars. Estimated daily intake (EDI) of heavy metals through dates consumption (100 gram/person/day) for As and Pb exceeded the Provisional maximum tolerable daily intake from some locations. Although Cd content was exceeding MAL; however, its EDI is well within safe limits of Provisional maximum tolerable daily intake. From EDI data, hazard risk index was also calculated, which predicted that both As and Pb can pose potential health hazards to dates consumers in Saudi Arabia. However, Pb contributed greater health risks due to date fruit consumption as compared to Arsenic.
