摘  要:
对重庆市17个商品粮基地103个水稻土进行采样分析和评价。结果表明,调查土壤中Cd、Cu、Zn、Pb、Hg 5种重金属平均浓度分别为(0.390±0.180)、(18.526±10.400)、(89.382±22.800)、(55.069±17.600)、(0.098±0.076)mg/kg。17个商品粮基地间的Cd、Cu、Pb、Hg含量各自存在极显著差异(P<0.01),而Zn含量差异不显著(P=0.05)。环境质量综合评价显示,重庆市商品粮基地部分水稻土受到重金属污染,污染程度为潼南>秀山>綦江>永川>合川>荣昌>大足>南川>江津>梁平>垫江>长寿>铜梁>开县>忠县>渝北>巴南,主要污染物为Cd。

摘  要:
This study aimed to analyze and assess 103 representative soil samples from 17 food-supply bases in Chongqing.The results showed that the average contents of heavy metals was respectively Cd(0.390±0.180),Cu(18.526±10.400),Zn(89.382±22.800),Pb(55.069±17.600) and Hg(0.098±0.076) mg/kg,and the contents of Cd,Cu,Pb and Hg in soils from different bases showed significant differences(P<0.01),but the Zn content varied slightly(P=0.05).The heavy metal pollution degree in different bases followed a sequence of Tonglan>Xiushan>Qijiang>Yongchuan>Hechuan>Rongcang>Dazu>Nanchuan>Jiangjin>Liangpin>Dianjiang>Changshou>Tongliang>Kaixian>Zhongxian>Yubei>Banan,and mostly by Cd.
