| Summary: | Heavy metal contamination in landfill is one of the major concerns in order to avoid harmful effects towards health living and environment. The aim of this study is to come out with the distribution of the concentration of Cadmium (Cd) and Chromium (Cr) contaminated in soil of closed landfill, to compare it with the United States Environmental Protection Agency (USEPA) soil standard. The 200 grams (g) of 25 soil samples were taken at 25 points from a newly closed landfill in Ulu Tualang, Temerloh at two (2) parts of soil partition which are in surface (0-2 inch) and subsoil (2-10 inch), respectively. The sample was processed using acid digestion method of SCL (Southern California Laboratory) and was analyzed using Flame Atomic Absorption Spectrometry (FLAA). The range of Cd concentration that had been analyzed is from 49.4 to 66.15 mg/kg, while for Cr concentration determination, the result showed that the range is between 5.35 to 71 mg/kg. Available results from the landfill indicated that all concentration of Cd is exceeded the USEPA soil standard while the data for Cr is under the control value. The result can be used in future for reference and if possible, it may be needed for soil treatment if there are any future plans or activities for the landfill. |
