Abstract
Concentrations of six trace elements [chromium (Cr), nickel (Ni), copper (Cu), cadmium (Cd), lead (Pb) and arsenic (As)] were assessed in ‘non-piscine protein source’ foodstuffs (meat, milk and eggs) to evaluate contamination level and human health risks in Bangladesh. The range of Cr, Ni, Cu, Cd, Pb and As in the investigated foodstuffs was 1.24–2.17, 1.29–2.56, 0.92–2.31, 0.12–0.44, 0.15–0.48 and 0.14–0.57 mg kg fresh weight-1, respectively. The estimated mean levels of most of the elements were higher than the maximum allowable concentration (MAC) for dietary foods. The estimated daily intakes (EDIs) of Cr and Cd were higher than the maximum tolerable daily intake (MTDI) for children, indicating that they are more susceptible to toxic elements through food consumption. The target hazard quotients (THQs) and target carcinogenic risk (TCR) of As (THQ?>?1 and TCR?>?10-4) for both the adults and children suggest that the consumers of non-piscine foodstuffs (especially cow milk and chicken meat) are exposed chronically to metal pollution with carcinogenic and non-carcinogenic health consequences.
