In an attempt to understand changes in sea environment owing to constructing fishing port in the Eastern Sea ports, by comparing the data from Environmental Impact Assessment (EIA) on 2006 and those obtained from post-Environmental Impact Assessment (post-EIA), the impact of the construction on the sea environment, and the temporal and spatial distributions of sea environmental parameters were analyzed. After analyses, it could be found that the values were increased in all the items except pH, influencing nutritional salts (T-N, T-P) and SS mostly with the severest degrees. Although the heavy metals except Hg were detected since construction, the values were lower than the standard ones stipulated in the environmental standards in areas of the sea (standards for short periods in the light of protecting sea environment). Furthermore, the fact that heavy metals were detected after beginning offshore breakwater construction, although the heavy metal concentrations were lower than the criteria from sea water environmental standard, means that the port facility construction influence the concentration of heavy metals in the seawater.
