Distribution of Cu Metal on the Soil around the Landfills of Antang, Makassar City

[摘要] The waste processing technique in the landfill of Antang, Makassar City, South Sulawesi, Indonesia, uses the Open Dumping system that potentially pollute the surrounding soil. The contamination of heavy metals in the soils is the center of attention from an ecological point of view. Research has been done on the distribution of heavy metal Cu on the soil around Antang landfill. This study aims to analyze the heavy metals potential distribution to the soil around Antang TPA. The sample point was divided into 4 Lines, 2 Lines are in the direction of the groundwater flow (Line A and Line C) while the other 2 Lines are perpendicular to the groundwater flow (Line B and Line D). At the point of 0 m with a depth of 0 to 10 cm, 10 to 20 cm and 20 to 30 cm. The total soil samples whose heavy metal elements analyzed by using ICP-OES method are twelve samples. The heavy metal Cu on Antang Landfill soil has spread over the soil surface (Top Soil) vertically. The results show that the soil around Antang Landfill is contaminated with the heavy metal elements that exceed the value of Indonesian Intervention as a soil contaminant. The Cu metal concentrations for Line D at the depth of 0 to 10 cm and 10 to 20 cm are105 ppm and 103 ppm which were already above the average. Meanwhile, for Line A, Line B and Line C are still below the average allowed by the Government of the Republic of Indonesia and the General Control of Drugs and Food as a soil contaminant. The pH soil varies from 4.82 to 6 (acidic). Therefore, it requires proper remediation or preventive measures to prevent the risks on the humans and the environment.
