In this survey the results showing the highest values among the analyzed data of all specimens are summarized as follow. At Kwangyang bay Cu in the fishery was detected up to 1.208ppm and the level of Cu and Pb in sediment of this area were 2.13 and 4.34ppm, respectively. The contents of Hg in fishery and sediment of Yeosu bay were 0.102 and 0.032ppm. The levels of Pb in fishery and seawater of Sunchon bay were 0.039ppm and 0.013$\mu\textrm{g}$/L, respectively. At Posung bay the contents of Cd were 0.277ppm, 0.09$\mu\textrm{g}$/L and 0.08ppm in the specimens of fishery, seawater and sediment, respectively. The analyzed data of all specimens at Keamundo were very low level or undetectable. Of the 6 fishery samples, Charybdis japonica showed the upper level of Hg, Cu, Zn, Mn as 0.092, 1.905, 6.64, and 46.34ppm, respectively. The contents of Pb and Cd in Batillus cornatus were 0.045 and 0.38ppm respectively and other fishery had low level of heavy metal. In this study the contents of heavy metals analyzed in all specimens showed nearly natural occurrence level which is under the legal limits.
