摘要：
Heavy metal contamination from abandoned mine areas is a major threat
for the environment. The study objective was to categorize the most
polluted mine areas among 44 mine sites at the four cities of Chungcheongbuk-do
province in South Korea. Both water and soil samples were collected
from the mine area. The pH of the water and soil ranged from 3.6
to 8.5 and from 4.1 to 9.1 respectively. A significant amount of
arsenic (As), cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb),
zinc (Zn) and mercury (Hg) occurred in soil samples collected from
the mine areas (0.2 to 42.4, 0.7 to 8.6, 10.7 to 430.2, 5.8 to 49.8,
2.1 to 122.8, 37.4 to 359.4 and 0.2 to 11.4 mg kg-1 respectively).
The surrounding available waters also carried high contents of Cd,
Cu, Pb and Zn, generally exceeding the fresh water acute and chronic
criteria. Each mine site was ranked according to the Integrated
Pollution Index (IPI). The normalized pollution index (PIn) for water
and soil, and the Survey Index (SI) were used to determine IPI.
The highest polluted mine site exhibited an IPI value of 0.6394.
IPI was introduced to prioritize the research sites for further
precise investigation.
