Abstract
Soil contamination survey was conducted during March - July, 2017 to obtain soil contamination profile of 16 organic and inorganic contaminants in Hanam industrial complex located in Gwangju, Korea. The concentrations of all surveyed contaminants except Cd showed were within 0.3~1.5 times of their natural background levels. Cd showed concentrations as high as 6.9 times of the background level, signifying the influence of the metal processing facilities in the complex. The concentrations of Zn, Pb and Hg in areas nearby industrial facilities were 1.3~5.5 times higher than those within the facility and green area. The concentration of Cu in the green area was 1.4~2.9 times higher than in other areas. The Soil Pollution Index (SPI) analysis revealed 54% of the total area belong to first-grade soil, 43% to second-grade, and 3% to third-grade. The Enrichment Factor (EF) of Zn, Pb, and Cd were 9.2, 15.6, and 88.5, respectively, indicating high accumulation and contamination of the soil with Cd.
