SUMMARY

Soil pollution has been occurring globally. Waste from industrial production zones is considered one of the main causes of soil pollution. The concentrations of Arsenic (As), Cadmium (Cd), Copper (Cu), Lead (Pb), and Zinc (Zn) in 4 water samples and 12 soil samples collected from drainage ditches and agricultural areas around the industrial zone were used to assess soil pollution at the mineral extraction industrial zone in Dak R’Lap district. The analysis results showed that 5/12, 8/12, and 4/12 soil samples had As, Cd, and Cu concentrations at near-pollution levels, and 1/4 water samples had As concentrations at near-pollution levels. Soil in areas surrounding the industrial zone was not found to be polluted. However, 41,729 hectares were at risk of pollution by As, Cd, and Cu in both soil and water. Potential sources of pollution include solid waste from mining activities, water and air emissions from mining operations, and waste from workers’ daily activities and machinery operations.

Keywords: soil pollution, industrial zone soil pollution, industrial zone, Dak R’Lap industrial area.
