Laterally and Vertically Distribution of Cadmium (CD) Heavy Metal, Case Study of Antang Landfill, Indonesia

Abstract

Antang landfill is situated in the center of Makassar City, South Sulawesi Province, Indonesia. In its operation, Antang landfill implements the Open Dumping method, potentially causing soil contamination. This study is conducted to identify the distribution of heavy cadmium metal in the soil around the Landfill. There are four sampling points in this study: (sample R, sample X, sample Y and sample Z) 0 m, 5 m, and 10 m laterally and a depth of 0 to 10 cm, 10 to 20 cm, and 20 to 30 cm vertically. A total of 36 samples are analyzed for heavy metal content using the ICP-OES method. The result shows that cadmium (Cd) in this landfill has spread across the surface soil (topsoil) both vertically and laterally with varying intensities at each sample (sample R, sample X, sample Y and sample Z). The contamination level of cadmium in the soil around the landfill is considered low. Considering Makassar City in the future will still be faced with the problem of environmental pollution as a result of the development and increase of population, efforts to rehabilitate polluted soils should be concerned, such as the flushing method and phytoremediation.
