A study on the environmental pollution history in a zinc refinery and background areas was conducted by analyzing heavy metal concentrations and stable isotope ratios (13C, Pb) in pine tree rings. The δ13C ratio of pine tree rings in the zinc refinery (SN1, S6) and background areas (B3) increased from 1968 to 1987. However, since 1988, there have been regional differences in this value. The δ13C value of the pine tree rings in the S6 area was found to be negatively correlated with those in the SN1 area, and that in the B3 area showed a positive correlation with the average atmospheric temperature in the winter season. During the 1980 to 1990 period, the concentration of five heavy metals (Pb, Cd, Cr, Mn, and Zn) in the pine tree rings was 2-10 times higher than those during the last five years. Particularly, the concentration of zinc ion appeared to be higher (28.8 μg/g) than that of other ions such as lead (3.1 μg/g) and cadmium (3.1 μg/g). This indicates that there has been a higher correlation between heavy metal concentrations and environmental pollution history since 1970, when the refinery construction was completed. On comparing the lead isotope ratios in the pine tree rings using Laser Ablation-MC/ICP/MS, it was estimated that the lead source could vary with the seasons, but the changes in the heavy metal absorption mechanisms of pine trees will be considered.
