Health Risk Assessment of Heavy Metals in Irrigated Agricultural Crops, El‐Saff Wastewater Canal, Egypt
This study aimed to assess the extent of some heavy metals (Cd, Cr, Cu, Pb, Ni, and Zn) in wastewater irrigated soils and their translocation in different food (cabbage, onion, garlic, fava bean, wheat, peppermint) and feed (clover) crops as well as their potential risk on human and livestock. Crop samples were collected from farmlands along El‐Saff wastewater canal, southern Giza governorate, Egypt. The analysis of wastewater and soil samples indicated that most of the physicochemical parameters and heavy metals concentrations were within the limits proposed by FAO (1985) and FAO/WHO (2007) for irrigation water and agricultural soils, respectively. Heavy metals concentrations varied among different crop species, in particular Zn and Cu showed the highest concentrations. The order of heavy metals concentrations in different edible parts was Zn > Cu > Ni > Cr > Cd > Pb. The heavy metals transfer factors of edible parts revealed high translocation values of Zn, Ni, and Cu by fava bean, Cd by garlic, Cr by peppermint, and Pb by fava bean and onion. Except for Cr and Ni, most of the metal concentrations were found within the permissible limits regulated for health standard. Furthermore, the performed health risk index indicated low health risk for humans and animals if edible parts from studied crops are consumed. Regular monitoring of heavy metal concentration in wastewater, soil, and agricultural crops in the study area is necessary.
