Objectives: This study was conducted in order to examine the relationship between heavy metal concentrations
in the soil and the level of heavy metals in the blood or urine of 216 local residents living near abandoned metal
mines.
Methods: Residents around abandoned metal mines were interviewed about their dietary habits, including
seafood consumption, medical history, cigarette smoking, and drug history. Metal concentrations in the soil were
determined by atomic absorption spectrophotometer (AA-7000, Shimadzu, Japan). Lead (Pb) and cadmium (Cd)
contents in the blood or urine were analyzed by GF-AAS (AA-6800, Shimadzu). Mercury (Hg) contents in the
blood were determined by means of a mercury analyzer (SP-3DS, NIC). Arsenic (As) content in the soil and
urine were measured by a HG-AAS (hydride vapor generation-atomic absorption spectrophotometer).
Results: The heavy metal concentrations in the soil showed a log normal distribution and the geometric means
of the four villages were 8.61 mg/kg for Pb, 0.19 mg/kg for Cd, 1.81 mg/kg for As and 0.035 mg/kg for Hg. The
heavy metal levels of the 216 local residents showed a regular distribution for Pb, Cd, Hg in the blood and As
in the urine. The arithmetic means were3.37 μg/dl for Pb, 3.07 μg/l for Cd and 2.32 μg/l for Hg, 10.41 μg/l for
As, respectively.
Conclusions: As a result of multi-variate analysis for the affecting factors on the bodily heavy metal
concentrations, gender and concentration in the soil (each, p<0.01) for blood lead levels; gender and smoking
status (each, p<0.01) for blood cadmium levels; gender (p<0.01) for urine arsenic levels; gender, age and
concentration in the soil (p<0.01) for blood mercury levels were shown to be the affecting factors.
