Health Risk Assessment of Heavy Metal in Moso Bamboo Shoots from Farm Markets, China

The contents of 6 kinds of heavy metals (Pb, Cr, Cd, As, Cu, Ni) in moso bamboo shoot were measured by inductively coupled plasma-mass spectroscopy (ICP-MS). The health risk of the 6 kinds of heavy metals was assessed by the target hazard quotients (THQ). The mean contents of Pb, Cr, Cd, As, Cu and Ni in all analyzed bamboo shoots were 6.19 similar to 92.8, 1.38 similar to 137, 1.22 similar to 35.5, 1.14 similar to 7.48, 224 similar to 1266 and 31.4 similar to 381 mu g kg(-1), respectively. The contents of these heavy metals in all samples were below the corresponding maximum limits established by Ministry of Health P. R China. It is observed that each heavy metal THQ value was below 1.0. The TTHQs of the heavy metals for adults and children were 0.116 similar to 0.152 and 0.165 similar to 0.216, the results indicate that the ingestion of moso bamboo shoots will not bring risks to residents.
