In order to grasp the recent status of sea water pollution with heavy metals such as Pb, Cd, Cu, Fe, Mn, Ni and Zn, measurements of samples with an atomic absorption spectrophometer were performed. Samples of sea water, sea-weed, and shell fish were collected at harbour cities located along the Coast of the Korea Peninsula such as Ganghwa, Asan, Daecheon, Janghang, Mogpo, Namhae, Samcheonpo, Goeje, Masan, Busan, Ulsan, Pohang, Yeongdeog, Uljin, Samcheog, Gangreung, and Sogcho.
The summarized results of the study were as follows;
1. Heavy metal concentrations of sea water were variable by area showing 0. 561.97 of coefficient of variation, and the highest concent of Cd in the Sample from Asan, Cu from Sogcho, Fe from Samcheonpo, Mn from Pohang, Ni from Namhae, Pb from Busan, and Zn from Yeongdeog.
2. Heavy metal concentration of sea-weed were less variable than that of sea water showing 0.481.86 of coefficient of variation, and the highest content of Cd in the sample from Daecheon, Cu from Mogpo, Fe and Mn from Samcheonpo and Ni, Zn and Pb from Namhae.
3. Heavy metal concentration of shell fishes were determined for 2 groups, sea mussels and clams.
As for sea mussels, coefficient of variation ranged 0. 342-12 and showed the highest content of Cd in the sample from Busan, Cu, Mn and Zn from Mogpo, Fe from Daecheon, Ni from Yeongdeog, Pb from Sogcho. And as for clams, coefficients of variation were very low except 0.99 of Pb and showed the highest content of Cu from Yeongdeog, Ni from Goeje, Pb from Namhae, Zn from Ulsan, and Cd, Mn and Fe from Busan.
4. Ordinal rank of heavy metal pollution by area was made with sementic scores. In general,
cities located along the South Coast such as Samcheonpo, Namhae, and Busan were the areas where the status of heavy metal pollution was highest.
5. Correlation coefficients between metals by sample were extreamly low. except the one of 0.53(p<0.05) between clam and sea water in general. The coefficient of 0.54(P<0.05) in case of Fe between clam and sea water was highest.
