摘要： 为了解浙西南山区主产县（区、市）竹笋基地土壤重金属的状况，保障竹笋质量安全，选择安吉、临安、余杭等8 个县44 个竹笋基地，采集132 份土壤样品进行As、Hg、Pb、Cd、Cr、Cu和Zn 7 种重金属的含量分析，以森林食品产地环境通用要求(LY/T 1678—2014)为依据，进行单因子污染指数、综合污染指数评价。结果表明：研究区域7 种重金属含量范围分别为0.79~24.80、0.03~1.05、7.64~316.69、0.00~4.50、2.47~232.21、5.33~542.20、38.63~436.84 mg/kg；变异系数在64.5%~268.5%之间；综合污染指数大小顺序为富阳＞安吉＞德清＞余杭＞临安＞龙游＞莲都＞遂昌。相关分析和聚类分析结果表明：Cd、Zn和As 可能具有同源性或是伴生关系；As、Hg、Cr、Cu和Pb 呈现相互伴随的复合污染现象；而Cd表现其独特的污染来源。8 个县竹笋生产基地土壤重金属环境质量总体良好；部分地区Pb、Hg和Cd处于轻度及以上污染水平，栽培和生产中应采取一定的措施防控Pb、Hg和Cd污染。

Abstract: In order to understand soil heavy metal condition of bamboo shoot producing areas in South-West Zhejiang Province and protect quality safety of bamboo shoot, 7 heavy metals (As, Hg, Pb, Cd, Cr, Cu and Zn) content from 132 soil samples of 8 cities(Anji, Linan, Yuhang and so on) were analyzed, single factor containment index and synthesis containment index were evaluated based on the environmental general requirements for production area of edible forest product (LY/T 1678—2014). The results showed that the content of the 7 heavy metals was 0.79-24.80, 0.03-1.05, 7.64-316.69, 0.00-4.50, 2.47-232.21, 5.33-542.20 and 38.63-436.84 mg/kg, espectively; the range of variation coefficient was from 64.5% to 268.5%; The order of synthesis containment index was Fuyang＞Anji＞Deqing＞Yuhang＞Linan＞Longyou＞Liandu＞ Suichang. Correlation analysis and clustering analysis showed that there was homology or associated relationship between Cd, Zn and As; As, Hg, Cr, Cu and Pb showed combined pollution phenomenon; while Cd showed an unique pollution source. Soil heavy metal environmental quality of these 8 cities was fine, Pb, Hg and Cd belonged to light polluted level in some areas. Prevention and control should be taken in the process of cultivation and production.
