绍兴市春笋重金属含量及其质量安全评价

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

    摘要
  • 摘要: 在绍兴市5个毛竹（Phyllostachys heterocycla cv. Pubescens）主产区采集213份春笋样品，测定了砷、铅、镉、汞和铬5种重金属的含量，以食品安全国家标准食品中污染物限量为评价标准，采用单因素污染指数和综合污染指数法对研究区域的毛竹春笋中的重金属进行了质量安全风险评价。结果表明：5种重金属的检出率均超过98%，根据GB2762-2012，铬、砷、镉和汞未超标，铅有5个批次超标；5种元素相对含量高低顺序为铅＞铬＞汞＞镉＞砷，其中铅含量平均值达到标准限量的64.6%，其它4种元素均低于标准限量的的32%；从春笋的不同产地分析，上虞区的春笋最为安全，柯桥区的综合污染指数最高，但综合污染指数均小于0.7，说明绍兴市春笋受重金属污染的程度较小。

     

    Abstract: 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
