Assessment of Riverbed Sediments Originated from Volcanic Ash Soils in Jeju Island

A study assessing riverbed sediments from volcanic ash soils on Jeju Island reveals that high levels of phosphorus (TP), chromium (Cr), and nickel (Ni) are primarily of natural origin, linked to volcanic activity. Two sampling stations exhibited 'Very Poor' pollution status due to elevated TP content, while the third showed a 'Fair' status with Class II Cr and Ni pollution. Comparisons with previous studies confirmed that these pollutant levels mirror those found in original volcanic ash soils, suggesting minimal anthropogenic influence. The research underscores the need for tailored assessment criteria that account for Jeju Island's unique geological characteristics.
