摘要
本研究针对湖南某重金属污染场地开展土壤环境调查,布设14个点位,采集66个土壤样品,分析土壤主要污染物。结果表明,该场地土壤主要存在钒、砷、铬等重金属污染,超标率达到了40%以上,大部分区域土壤污染深度在2m以上。土壤中污染物会随雨水的冲刷向周围扩散,使周边的土壤、水体、农田等受到污染,应引起重点关注。研究结果可为同类场地的土壤调查提供参考。
The study is focus on an investigation about soil environment whose datas were taken in one heavy metal pollution site of Hunan province.The investigator set up 14 sites and collected more than 66 soil samples to analyze the main soil pollutants.The results show that the site soil is mainly contaminated by vanadium,arsenic,chromium and other heavy metals,whose exceeded rate is more than 40%.And the depth of the soil pollution in most areas is more than 2m.The pollutants in the soil are spread to the surrounding with the erosion of rain so that the surrounding soil,water,and the farmland are affected too,which should be paid more attention to.The results in the research can provide reference for soil investigation of similar sites.
