- Abstract
- This study aims to determine the pollution levels of nine kinds of heavy metals (As, Cd, Cu, Cr, Hg, Mn, Ni, Pb and Zn) in lake Shihwa, which is susceptible to the inflow of pollutants, and the levels of heavy metal exposure to the fish and shellfish. Shihwa lake`s water quality did not exceed the short-term standard for protection of marine ecosystem, but concentration of As, Cu, Cr, Hg, Ni and Zn exceeded the long-term standard for protection of marine ecosystem standard. In comparison to the prior research performed in 2010, Cr, Ni, As and Zn have decreased by 4.1 times. However, when compared to the Saemangeum lake, which has a similar environment to lake Shihwa, Cu, Ni, Hg, Mn and Zn was 244.4 times higher. The rate of Pb, Cd and Hg in fish’s muscles did not exceed the average values set by the marine safety standard. However when compared to the fish from the Korea coast, the rate of heavy metals was 9.7 times higher on average. The rate of heavy metals in fish`s livers was on average 26.8 times higher than in the muscle. In the case of shellfish, the rate of Pb, Cd, and Hg did not exceed the standard values, but in comparison to the shellfish from the south coast, the rate of heavy metals was 6.2 times higher on average. In particular, Mn (153.5 times) from fish and Cd (14.7 times) from shellfish were found in high amounts, indicating a concerning level of the specific heavy metals.
