Heavy Metal Content in Bamboo Shoot from Shaoxing and Quality Safety Evaluation

Measurements were carried out on content of As, Pb, Cd, Hg and Cr in 213 samples of spring bamboo（Phyllostachys heterocycla cv. Pubescens）shoot collected from 5 areas of Shaoxing, Zhejiang province. Quality safety(QS) evaluation with single factor pollution index and comprehensive pollution index demonstrated that detection rate of 5 heavy metals reached 98%, but As, Cd, Hg and Cr content was safe according to GB 2762-2012, 5 samples had over-limit of Pb. Analysis on detection result indicated that shoot from Shangyu had the most quality safety, and that from Keqiao was the last, but comprehensive pollution index was lower than 0.7, meaning that spring shoot from Shaoxing was safe
