中文摘要：

目的了解农田重金属镉的污染状况,为制订相关防制措施提供依据和支持。方法于2011—2013年对全区29个县（区）的580个行政村设立农田土壤监测点进行采样,利用电感耦合等离子体质谱法（ICP-MS）对土壤镉的含量进行检测。结果 2011—2013年共采集农田土壤1 740份,29.83%的土壤镉含量低于自然背景值;镉检测结果范围为：0.022-91.5 mg/kg,算术平均值为0.86 mg/kg,中位数为0.32 mg/kg,标准差是3.47;镉的点位超标率为49.94%,重度污染比例为18.18%、中度污染比例为14.73%、轻度污染比例为20.25%、轻微污染比例为46.84%。结论农田镉超标率维持在一个较高水平。应进一步开展土壤污染状况详细调查,加强对重点地区的人群健康监测,找出人群健康效应关系。

英文摘要：

Objectives To understand the pollution of cadmium in soil, port for Guangxi government to formulate prevention measures. Methods in order to provide evidence and sup- Soil samples were collected from the farmland in 580 administrative villages of 29 counties （districts） in 2011-2013, and the content of cadmium was detected by inductively coupled plasma mass spectrometry （icp-ms）. Results The cadmium content in 1 740 soil samples were in the range of 0. 022 - 91.5 mg/kg, with an average value of 0. 86 mg/kg, a median value of 0.32 mg/kg, a standard deviation of 3.47, and only 29.83% of the values were lower than the natural background （0.2 mg/kg）. The exceeding rate of cadmium in soil samples was 49.94% ; and the degree of pollution in polluted points were 18.18% in severe level, 14.73% in moderate level, 20.25% in light level and 46. 84% in slight level. Conclusions With a higher exceeding rate of cadmium pollution in soil, more detailed investigation in key areas should be carried out to identify the relationship between cadmium pollution and people＇s health.
