Assessment of trace metal contamination of soil in a landfill vicinity: A southern Africa case study

This study quantified pollution of soils by trace elements at the Roundhill landfill, South Africa using indices and multivariate statistics. Soils were collected and assayed for trace metals using x-ray fluorescence. | Assessment of trace metal contamination of soil in a landfill vicinity A southern Africa case study Current Chemistry Letters 9 2020 171 182 Contents lists available at GrowingScience Current Chemistry Letters homepage www.GrowingScience.com Assessment of trace metal contamination of soil in a landfill vicinity A southern Africa case study Joan Nyikaa Ednah Onyaria Megersa Dinkab and Bhardwaj Shivanic a University of South Africa Department of Civil and Chemical Engineering University of South Africa Florida science campus Cnr Christian de Wet Road and Pioneer Avenue Johannesburg South Africa b University of Johannesburg Department of Civil Engineering Science University of Johannesburg APK Campus 2006 Johannesburg South Africa c University of South Africa Nanotechnology and Water Sustainability Unit University of South Africa Florida science campus Cnr Christian de Wet Road and Pioneer Avenue Johannesburg South Africa CHRONICLE ABSTRACT Article history Contamination of soils by trace elements is a worldwide concern and has negative effects on Received October 8 2019 environmental sustainability. Geochemical assessment of soils using appropriate indicators Received in revised form and pollution indices has received much attention in recent years in efforts to rehabilitate this November 21 2019 resource. This study quantified pollution of soils by trace elements at the Roundhill landfill Accepted February 18 2020 South Africa using indices and multivariate statistics. Soils were collected and assayed for Available online February 18 2020 trace metals using x-ray fluorescence. Pollution indices classified soil contamination levels while multivariate statistical analysis was conducted using principal component and cluster Keywords analyses. Findings showed that concentrations of all elements decreased with increasing Contamination distance from the landfill. Low to extremely high pollution was evident in all soils and Cr had Landfill the highest values compared to .
