| 摘 要： | 本文利用电感耦合等离子体质谱仪对广东蔗区有代表性区域的甘蔗种植土壤中Cd、Hg、As、Cu、Pb、Cr、Zn、Ni重金属含量进行监测，利用酸度计对土壤pH值进行监测，采用单因子指教法和多因子综合评价法评价重金属污染程度。结果表明：土壤以酸性为主，重金属的污染指数范围为0．078～1．3，其中As为1.3，受到轻度污染，Cd为0．94，处于警戒线；综合污染指数为1．1，说明广东蔗区土壤受到重金属轻度污染。

| Abstract: | In this paper, heavy metals including Cd, Hg, As, Cu, Pb, Cr, Zn, Ni in the soil of Guangdong sugarcane region were monitored by inductively coupled plasma mass spectrometer, and soil pH was monitored by pH meter. The heavy metal pollution was evaluated through the single factor index method and the Nemero synthesis index evaluation method. The results showed that most of the sugarcane soil was acidic, the heavy metal pollution index ranged from 0.078 to 1.3. The pollution index of As was 1.3, which was in light pollution, and the pollution index of Cd was 0.94, which was in warning level. The comprehensive pollution index was 1.1, indicating that the soil of Guangdong sugarcane region was in light pollution of heavy metals. |
