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

Abstract

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 ∼ 92.8, 1.38 ∼ 137, 1.22 ∼ 35.5, 1.14 ∼ 7.48, 224 ∼ 1266 and 31.4 ∼ 381 µg 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 ∼ 0.152 and 0.165 ∼ 0.216, the results indicate that the ingestion of moso bamboo shoots will not bring risks to residents.
