The accumulation of heavy metals including Cd, Cu, Mn, Zn and Pb in various organs of shellfish which is the reasonable bio-indicator for hazardous substance contamination on lotic habitats with relatively limited mobility through waterbody was studied. Meretrix petechialis, Scapharca broughtonii, and Scapharca subcerenate from West Coast of Korea and Osaka Bay of Japan were selected to compare heavy metal contamination in adduct muscle, foot muscle, gill, mantle, and visceral organ of marine shellfish. Semisulcospira spp. from various area include West Coast of Korea and Han river were analyzed to compare heavy metal concentration in whole tissues between marine water and fresh water. A regional differences among Hong-chun, Kang-chon, Keum-nahm, Kah-pyung, Seo-rak, and Pal-dang of heavy metal concentration in Semisulcospira gottche was compared. There are significantly differences in mean concentration of Cd, Cu, Mn, Zn, and Pb among organs and species of M. petechialis, S. broughtonii, and S. subcerenate (ANOVA -F=60.31, p<0.001; F=36.88, p<0.001; F=27.78, p<0.001; F=9.39, p<0.001; F=2.91, p<0.001, respectively). The highest mean concentration of Cd with 0.680ppm was observed in gill and the lowest mean concentration of Cd with 0.082ppm was observed in foot muscle. The mean concentration of Cd with 0.349ppm in S. broughtonii was significantly different from other two species with 0.255 and 0.175ppm. Both Cu and Mn were highly accumulated in gill and mantle compare to other organs. Both gill and mantle had significantly different mean Cu concentration with 4.937 and 4.950ppm, respectively compare to both adduct muscle and foot muscle with 2.129 and 2.029ppm, respectively after Duncan's Multiple Range Test. The mean concentration of Cu with 1.900ppm in S. broughtonii was significantly lower then those of other two species. Both Zn and Pb were highly accumulated in gill compare to other organs. The mean concentration of all tested heavy metals except Cu in S. broughtonii were significantly higher than those of other species. There are significantly differences in mean concentration of all tested heavy metal except Cd between whole tissue of marine Semisulcospira spp. and fresh water Semisulcospira spp. Fresh water Semisulcospira spp. had high mean concentrations of Mn, Zn, and Pb while marine Semisulcospira spp. had higher mean concentrations of Cu. The mean concentrations of all tested heavy metals except Pb in Semisulcospira gottche from various area in Han River was significantly different among sites. The mean concentration of Cd in S. gottcheu from Hong-ehun, Cu in S. gottcheu from Kang-chon and Kah -pyung, Mn in S. gottcheu from Kah-pyung and Paldang, and Zn in S. gottcheu from Pal -dang was higher than those of other sites.
