Abstract

Trace amount of heavy metals in rain waters were determined after preconcentration by coprecipitaion technique. Indium was selected as a coprecipitating reagent and concentrated heavy metals were analyzed by a conventional AA spectrometer. Two areas, Cheng-Won and Tae-Ahn, were selected and comparison. The concentrations of Pb and Cd in Cheong-Won (raural) area were 14.3 .pm. 8.0 ppb and 2.77 .pm. 5.37 ppb, respectively. These values are higher than those of Tae-Ahn, which indicates that even a rural area is polluted by a nearly industrial area (Cheong-Ju). The isotope ratios of lead in rainwaters were very similar to theos of aerosol particles.
