Concentrations of selected heavy metals in food from four e-waste disassembly localities and daily intake by local residents.
This study was conducted to estimate the total daily dietary intakes of the five heavy metals As, Cd, Cr, Hg, and Pb for residents living in five villages located in the Zhejiang province of China. The highest dietary intakes of the five heavy metals were all observed in the four e-waste disassembly localities. These findings suggested that these metals from e-waste might have entered into the food chain. Rice appeared to be the food group showing the highest contribution to the individual dietary intakes of the individual metals. The dietary intakes of As for residents living in the five study localities were approximately 1.3 to 3.4 times higher than the pTDI (140 microg day(-1)). In comparing with those results reported recently in the literature, residents living in the disassembly localities appeared to be at greater health risks of As, Cr, Hg, and Pb than those living in the control town.
