Mobility of heavy metals in soils of arrangement municipal solid waste

Abstract

The hydrodispersive knowledge of soil in movement of heavy metals is fundamentally important to prevent and remediate environmental damages. Therefore, studies should be developed on interactions that occur in soils and contaminants solutions. Considering such information in literature, the study of this work is the mobility of Cd, Cu, Pb and Zn metals in three areas of municipal solid waste. The concentrations of ions in the effluent were analyzed using the miscible displacement methodology. Among these evaluated soils, PA presented the lowest potential in relation to leaching of trace elements evaluated. L soil has the highest vulnerability in terms of potential for groundwater contaminations, which requires a greater control in disposal of solid waste containing easily solubilized trace elements.
