Abstract— Heavy metal contamination of soil is of major concern Table 1 Methods of MSW disposal in Malaysia
from an ecological point of view. This study aims to characterize soil Treatment Achieved Target
samples from different sites of two waste disposal grounds in 2002 2009 2009 2020
Malaysia, to study heavy metal contamination in the landfill Recycling
environment. The soil samples were obtained at different depths from
2m to 35m deep to find the possibility of heavy metal migration posting
the waste cell into the deeper layers. Results from the analysis of Incineration
samples from Panchang Bedena landfill indicated that all heavy Inert landfill
metals analyzed were below the Dutch Intervention Standard for Soil Sanitary landfill
Remediation. Pb was at its highest concentration at the upper layer Other disposal sites
than the lower layer; displaying a decreasing trend at the deeper soil. Total
On the other hand, Fe and Zn depicted increasing trend where the
highest concentration was a
