General water quality parameters were measured, as a base-line study, for possible water pollution problems in the coastal waters of some important harbors and near-sea industrial complexes all around coastal zones of Korea from June 1 to October 15, 1977. The areas surveyed were near Mugho-Samcheog, Ulsan, Jinhae-Masan, Yeosu-Gwangyang, Mogpo, Gunsan and Incheon. Among the surveyed coastal areas, the Ulsan and the Jinhae-Masan areas showed high levels of dissolved oxygen, pH, COD and nutrients. Particularly, the surface waters of the Ulsan inner bay represented COD 15.6mg/l and NO$_<$TEX>2/-N 110$\mu\textrm{g}$/l. The surface layer of the Masan bay displayed pH 8.92 and NO$_<$TEX>3/-N 372$\mu\textrm{g}$/l, while 309$\mu\textrm{g}$/l of PO$_<$TEX>4/-P was recorded in the surface of the Haengam bay. In general it is shown that some coastal areas are presenting signs of pollution from man's activities.
