영문 초록

The pollution of PAHs(polycyclic aromatic hydrocarbons) is taking place extensively in the marine environment. The PAHs compounds are the most important component in various oil products and occur mainly as a result of anthropogenic activities. The field surveys to evaluate the pollution of PAHs in seawater and sea sediments of Jinhae bay were carried out in August, 2008. Sixteen PAHs which had been selected as priority pollutants by EPA (U.S. Environ Protection Agency) were analyzed. In seawater of Jinhae bay, the range and mean of dissolved total PAHs concentrations were shown to be 18.53~32.08(mean 23.81)ng/L at the surface water. The concentration in the seawater was shown to be high concentrations in stations of Masan bay where the main contaminated area of Jinhae bay while that other stations were shown to be similar concentrations. In sea sediments of Jinhae bay, the range and mean of total PAHs concentrations were shown to be 113.95~553.09(mean 247.84)㎍/㎏ dry wt.. The distribution of total PAHs was shown to be high concentrations in stations of Jindong bay and Gohyeon bay in the west inner bay of Jinhae bay rather than Masan bay where the greatest contamination is expected. The composition patterns of PAHs compound by the number of benzene ring between dissolved PAHs of seawater and PAHs of sea sediments were different each other. Low molecuar weight PAHs of dissoloved PAHs in seawater were in high concentration, while high molecular weight PAHs of PAHs in sea sediments were in high concentration. These results were due to physical and chemical characteristics of PAHs and were similar to those of other studies. The origin pattern of PAHs in sea sediment using composition and isomeric ratio of PAHs seem to be pyrolytic origin from various combustion presses such as use of fossil fuel and oil products in industrial activities as well as automobiles and home heating systems of urban area. The total PAHs concentrations in seawater and sea sediments of Jinhae bay are lower than the biological effect guidelines and other some results. The degree of PAHs contamination in Jinhae bay is not shown as being serious yet.
