目的开展农村土壤环境卫生监测,为促进土壤的可持续发展和利用,防止土壤污染提供科学依据。方法按照国家项目监测方案要求,根据《辽宁省农村环境卫生检测项目技术方案》,于2013年和2014年分别选取大石桥市下辖6个乡镇作为土壤环境监测抽样地点,共计采样40份进行检测。结果 2013年抽检的20份土壤样品中铅的含量平均为47.16 mg/kg,合格率为100%;镉的含量平均为0.328 mg/kg,合格率为45%。2014年抽检的20份土壤样品铅的含量平均为42.2825 mg/kg,合格率为100%;镉的含量平均为0.307 mg/kg,合格率为55%。结论应加强土壤重金属的监测,减少土壤对重金属的富集,降低健康风险。
Objective To carry out the monitoring of soil environmental health in rural areas and provide a scientific basis for promoting soil sustainable development and utilization and preventing soil pollution. Methods According to the requirements of the national project monitoring program, six rural towns under the jurisdiction of Dashiqiao were selected as soil environmental monitoring sampling sites in 2013 and 2014 according to the “Technical Scheme of Rural Environmental Sanitation Inspection Project in Liaoning Province”, 40 samples were collected for testing . Results The results showed that the average content of lead in 20 soil samples collected in 2013 was 47.16 mg / kg with a pass rate of 100%. The average content of cadmium was 0.328 mg / kg with a pass rate of 45%. The average content of lead in 20 soil samples collected in 2014 was 42.2825 mg / kg with a pass rate of 100%. The average content of cadmium was 0.307 mg / kg with a pass rate of 55%. Conclusion Monitoring of heavy metals in soil should be strengthened to reduce soil heavy metals enrichment and reduce health risks.
