摘要
通过采集上海市多个不同运营时间的在产生活垃圾焚烧厂表层土壤样品,检测了40个采样点中的Pb、Cd、Cu、Ni、Be、Co、As、Mn、Mo、Hg和C10-40等11种土壤特征污染物含量,研究了特征污染物含量水平、相互关联、空间分布等。综合相关性分析、空间分布分析的结果,铅与除砷、硒、钼外的其余特征污染物均有显著的正相关关系,可以作为生活垃圾焚烧厂的污染监测指示污染物,镉和铅的空间分布明显重叠,存在同源性可能性极大。结合聚类分析结果,运营时间最久的生活垃圾焚烧厂的污染情况最为特殊,这可能与早期生活垃圾焚烧厂土壤污染风险管控意识、生产运营过程中管理水平有关。
By collecting surface soil samples from several municipal solid waste incineration plants in Shanghai during different operating hours,the contents of Pb,Cd,Cu,Ni,Be,Co,As,Mn,Mo,Hg,and C10-40 in 40 sampling points were detected.And the content levels,correlations and spatial distribution of characteristic pollutants have been studied.Based on the results of correlation analysis and spatial distribution analysis,lead had a significant positive correlation with other characteristic pollutants except arsenic,selenium,and molybdenum,which could be used as pollution monitoring indicator pollutants in Multiple Solid Waste Incineration Plants.The spatial distribution of cadmium and lead obviously overlapped,and there was a great possibility of homology.Combining the results of cluster analysis,the pollution situation of the longest operating Multiple Solid Waste Incineration Plants was the most special,which might be related to the awareness of soil pollution risk control and management level in the production and operation process of the early multiple solid waste incineration plants.
