영문 초록

This study was performed to investigate background levels of barium (Ba), chromium (Cr) in Korean geological units. Also, the BCR sequential extraction method was conducted to identify chemical distribution of those compounds in Korean geological units and the simple bioavailability extraction test (SBET) was conducted to evaluate bioaccessibility. The soil samples taken from 17 sites were analyzed to survey background levels. The average concentrations and ranges for metals are as follows; Ba: 74.20 (23.25 ~ 171.28), Cr: 26.48 (6.74 ~ 75.89) mg/kg. The BCR sequential extraction method was conducted to identify chemical distributional existence of 2 elements of soils from each geological unit. Cr in soils mainly exist as residual form. However, in case of Ba, ion exchangeble and reducible form were relatively high compared with other metals. SBET bioaccessibility of metals were in the order of Ba (47.6%), Cr (0.8%). The results of speciations, and bioaccessibilities of metals in this study can be used to provide a fundamental data to set soil pollution standards and to evaluate the soil contamination level.
