摘要/Abstract

摘要： 以福建上杭、晋江、龙文和霞浦4个工、农业发展水平不同的典型区域为研究对象,测定了4个区域蔬菜基地的32个土壤样品及4类19种蔬菜52个样品的6种重金属含量,结果显示供试土壤中部分Cd、Pb、Hg超过国家标准。从供试土样重金属综合污染指数上看,有28.13%样品达到警戒水平,6.25%样品达到轻度或中度污染。供试蔬菜中有11.54%蔬菜受到不同程度的重金属Cd、Hg污染。就地域而言,上杭县污染最严重,污染蔬菜种类有小白菜、芥菜等;其次,晋江、龙文部分蔬菜受到污染;蔬菜重金属污染程度和蔬菜种类、工业发展程度存在一定相关性。就蔬菜种类而言,叶菜类污染指数最高;就重金属种类而言,主要为Cd、Pb污染。

Abstract: According to the industrial and agricultural development,Shang-hang,Jin-jiang,Long-wen and Xia-pu were selected as representative regions in this study.Thirty-two soil samples from 4 regions and fifty-two vegetable samples from 19 varieties were taken for detecting of heavy metal content.The results showed that the Cd,Pb and Hg contents of some soil samples were higher than it of national standard.Based on the comprehensive heave metal pollution index,the 28.13% of total soil samples reached in warning level of pollution and 6.25% were in moderate statuses.Among vegetable samples,the 11.54% of which were polluted in certain extent by Cd,Hg and the highest pollution index was found from leaf vegetables.The most of polluted samples were obtained from Shang-hang County,followed by Jin-jiang and Long-wen.The most of polluted vegetable species were cabbage,mustard,etc.Results indicated that the heavy metal contamination in vegetables was correlated in some degree with the species of vegetable and the development level of industrialization.The pollution resulted mainly with Cd and Pb.
