摘要：

Between 1992 and 1994, the distribution of 15 polycyclic aromatic hydrocarbons (PAHs) was investigated in seawater and surface sediments of the Baltic Sea, The analysis of PAHs in seawater is very difficult due to the low concentration, High separation capability is required, A method for analysing very low concentrations of PAHs is presented. The method is based on the high-performance liquid chromatography (HPLC) with fluorescence detection. The concentrations of PAHs in seawater are discussed in relation to water depth. A seasonal variation of PAHs in seawater was observed, with lowest concentrations occurring in summer and generally higher concentrations occurring in November. According to the regional distribution, elevated concentrations of PAHs were found in coastal regions of the Baltic Sea. The regional distribution of PAHs in surface sediments of the Belt Sea and the Arkona Basin were also investigated. The relationship between the content of PAHs and the percentage of total organic carbon in sediments is discussed.
