摘　　要：目的了解澄江县农村土壤中铅和镉污染情况,为土壤污染治理提供科学依据。方法采用分层随机抽样,分别对4个乡镇60个行政村的农田土壤进行采样、检测和评价,按照《土壤质量铅、镉的测定石墨炉原子吸收分光光度法》(GB/T 17141-1997)进行检验。结果共检测样品60份,清洁、无污染达到一级土壤的铅17份占28.3%,镉19份占31.7%;土壤环境尚清洁达到二级土壤的铅43份占71.7%,镉41份占68.3%,无三级土壤。结论 4个乡镇的60个行政村的农村土壤铅、镉含量均无超标情况,在清洁和尚清洁的范围内。但尚清洁说明已有污染物进入,应引起有关部门重视,做好预防,严格控制"三废"排放,提倡使用清洁能源,合理使用有机肥,提高土壤有机质含量,切实保护好土壤环境,维护人体健康。Objective To learn the pollution status of lead and cadmium in soil of rural area in Chengjiang county, so as to pro- vide scientific proof for soil pollution treatment. Methods Farm land soil samples were collected from 60 villages of 4 towns by stratified random sampling. Then these soil samples were detected and evaluated according to the determination of lead and cad- mium in soil by graphite furnace atomic absorption spectrophotometry （ GB/T 17141 - 1997）. Results In the 60 soil samples, lead level was found pollution - free in 17 first - class soil samples （28.3%） and 43 second - class soil samples （71.7%）, while cadmium level was found pollution- free in 19 first- class soil samples（31.7% ） and 41 second- class soil samples （68.3 % ）. No third - class soil sample was found in this detection. Conclusion The contents of lead and cadmium were not found exceeding the standards in soil of 60 administrative villages of 4 rural towns, which were within the scope of clean and slight clean. But it is clear that there are a few pollutants in the soil, so relevant departments should pay more attention to pre- vent further pollution and take effective measures to protect the soil environment quality, thus keeping human health.
