2013年-2017年巴彦淖尔市农田土壤中铅、镉、铬监测结果分析
|
摘要
目的了解和掌握巴彦淖尔市农田土壤中铅、镉、铬含量水平及其变化趋势,为相关决策部门提供技术支持和依据。方法按照《内蒙古自治区农村环境卫生监测工作方案》要求,依据GB/T 17141—1997《土壤质量铅、镉的测定》和HJ 491—2009《土壤总铬的测定》对巴彦淖尔市3个项目监测县农田土壤进行铅、镉、铬进行检测。结果 5年共检测样品300份,其中铅含量均符合国家一级土壤质量标准;镉含量75. 67%符合国家一级土壤质量标准,24. 33%符合国家二级土壤质量标准;铬含量78. 33%符合国家一级土壤质量标准,21. 67%符合国家二级土壤质量标准。结论巴彦淖尔市农田土壤中重金属污染水平不高,目前没有发现土壤质量有逐年下降的趋势,但仍需要引起相关部门的高度重视,积极采取防范措施。
Objective To understand the levels of lead,cadmium and chromium in soil from Bayannaoer and their changing trends,so as to provide technical support and basis for the relevant departments to formulate policies and measures. Methods According to the requirements of Inner Mongolia Autonomous Region Rural Environmental Health Monitoring Work Plan,GB/T 17141—1997 Determination of Soil Quality Lead and Cadmium and HJ 491—2009 Measurement of Soil Total Chromium,the farmland soil in a county of Bayannaoer was conducted for the detections of lead,cadmium and chromium. Results A total of 300 samples were tested in 5 years,of which 100% samples met the national first-class soil quality standards in lead content. 75. 67% samples met the national first-class soil quality standards in cadmium content,24. 33% samples met the national secondary soil quality standards in cadmium content. 78. 33% samples met the national first-class soil quality standards,and 21. 67% samples met the national secondary soil quality standards in chromium content. Conclusion The pollution levels of heavy metals in farmland soils are not high in Bayannur. No annual deterioration of soil quality was observed. However,it still needs to pay attention for the relevant departments to take proper preventive measurements.
