The present study investigated the heavy metal (HM) accumulation in some food items and associated potential human health risk in the Prakasam district. Food samples were collected from 9 villages of different mandals mainly comprising of rice, wheat, green gram, red gram, black gram, potato, and amaranthus. The HMs chromium (Cr), arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg) were analyzed by Inductively Coupled Plasma Mass Spectroscopy (ICPMS). The results showed that the HM concentrations in vegetables were higher than the cereals and pulses. The decreasing order of HM concentrations were observed as Cr > As > Pb > Cd > Hg, Cr > Pb > As = Cd > Hg and Cr > Pb > Cd > As > Hg in cereals, pulses, and vegetables, respectively. The dietary intake of cereals and vegetables contributed more exposure to HMs. The hazard index (HI) in case of cereals (3.648) and vegetables (1.003) exceeded 1 indicating the non-carcinogenic risk when these food items are consumed by adults. The HI in case of cereals (7.106) and vegetables (1.747) exceeded 1 indicating the health risks when these food items were consumed by children. The HI for cereals and vegetables in case of children is almost double to the HI of adults. The lifetime cancer risk was observed for Cr via consumption of rice and amaranthus, both in adults and children. In conclusion, health risk due to consumption of cereals and vegetables revealed both non-carcinogenic and carcinogenic risk for adults and children. The findings of the present study can be used for the development of potential strategies for risk control and management.
