摘 要:目的了解鞍山市农村土壤环境的质量状况,为相关部门采取有效措施加强污染监测与防控、提高土壤质量提供科学依据。方法采用《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)规定的方法进行检验。结果 2011年抽检的20份土壤样品中铅含量均达到二级标准,合格率为100%;镉含量17份达到二级标准,3份超过二级标准,合格率为85%。2012年抽检的20份土壤样品中铅、镉均达到二级标准,合格率为100%。结论2011年和2012年抽检地区的土壤样品均没有受到铅的污染,但部分地区的土壤样品受到了镉的污染,2011年镉的含量普遍高于2012年,尽管此次研究发现当地土壤重金属污染程度较轻,但也应当引起相关部门的重视。Objective To understand the quality status of rural soil environment in Anshan city, so as to provide scientific basis for relevant departments to take effective measures for monitoring and control of soil pollution and improve soil quality. Methods The soil samples were tested in accordance with "Determination of lead, cadmium in soil by graphite furnace atomic absorption spectrophotometry" (GB/T 17141 - 1997). Results In 2011, the lead content in 20 soil samples all reached the secondary standard, the qualified rate was 100%, while cadmium content in 17 soil samples reached the secondary standard, that in the rest 3 samples exceeded the secondary standard, the qualified rate was 85%. In 2012, the contents of lead and cad- mium in the 20 soil samples all reached the secondary standard, with a pass rate of 100%. Conclusion The soil samples in 2011 and 2012 were not contaminated by lead, but the soil samples of some areas have been contaminated by cadmium. The content of cadmium in 2011 is generally higher than that in 2012. Although it was found that the pollution levels of heavy metals were slight in local soil, it remains to be brought to the forefront by relevant departments.
