| 摘 要： | 按照国家相关标准,用单项污染指数法分析了贵州清水江沿岸柑橘园土壤pH值及镉、汞、砷、铅、铬的含量,并进行了土壤重金属残留安全性评价。结果表明,清水江沿岸柑橘园土壤重金属含量的大小顺序为Cr>Pb>As>Cd>Hg,且主要来源于成土母岩,受污染较小。各样本污染指数均小于1,除铅为尚清洁外,其余样品均为清洁,当地适宜发展无公害柑橘生产。

| Abstract: | According to the relevant national standard,the pH-value and the contents of cadmium,mercury,arsenic,lead and chromium of the soil in citrus orchard along the Qingshui River in Guizhou province were detected by using individual pollution index method,and the safety of soil heavy metal residue was evaluated.The results showed that the heavy metal content in the soil of citrus orchard along the Qingshui River was in the order of Cr>Pb>As>Cd>Hg,and the heavy metal mainly came from soil mother rock,which was less polluted.The pollution index of each soil sample was less than 1.The lead content in soil samples was at the slight cleaning level,and the content of other heavy metal all was at the cleaning level,which was suitable for the non-pollution development of citrus production. |
