吉林省松原油田井场周边农田土壤重金属含量特征及生态风险评价
Heavy Metals Content Characteristics and Ecological Risk Assessment of Surrounding Soil of Production Wells in Songyuan Oilfield of Jilin Province
摘要
Abstract
Heavy metals of Pb,Hg and As in farmland soil surrounding the production wells of Songyuan oilfield in Jilin Province were taken as the research object,the content characteristics,potential ecological risk and its influencing factors of Pb,As,Hg in soil were studied.The results showed that the average contents of heavy metal Pb,Hg,As were 6.392 8,0.0791,and 23.305 1 mg/kg,respectively,which were 0.33,2.20 and 2.39 times of their background values in soil,indicating that Hg and As were accumulated apparently in soil.4％ of Hg was in the moderate pollution status,16％ was in the medium-heavy pollution status,but Pb and As were almost in a state of non-pollution status.The potential ecological risk of heavy metals in the sequence of decending was Hg,As,Pb,and 20％ of Hg was in the strong-very strong ecological risk levels.Soil heavy metal contents were affected by pH,OM content obviously.关键词
