포말분리법을 이용하여 해수 중의 단백질 제거 실험을 수행한 결과 유입 단백질의 농도가38.0g/m일 때 제거 속도가 최대였으며 0.48min의 수력학적 체류시간에서 9.65g protein/m3.min의 가장 높은 단백질 제거속도를 얻을 수 있었다.

Temperature data observed by NERDA and the satellite infrared imagery off the east coast of Korea from 1994 to 1998 for 5 years were analyzed to study the distribution, temporal change, and structure of mesoscale eddies appearing almost permanently off the east coast of Korea. Typically, the eddy distribution can be characterized by two cases; two-eddy case and three-eddy case. In 1995 and 1996, there were only two eddies, one northeast of Sokcho and the other around the Ulleung Island. In 1994, 1997 and 1998, three eddies were located off Wonsan, Sokcho and Youngduk. For two-eddy case, the Ulleung Eddy surrounded the Ulleung Island, whereas this eddy is located south of the island in three-eddy case.

The adsorption and leaching of organophosphorus pesticide, EPN are investigated in Namwon soil(black volcanic soil), Aewol soil(very dark brown volcanic soil) and Mureung soil(dark brown nonvolcanic soil) sampled in Cheju Island. The organic matter of Namwon soil, Aewol soil and Mureung soil is 19.8%, 6.2%, 2.4%, respectively. The cation exchange capacity of Namwon soil, Aewol soil and Mureung soil is 24.8 meq/100g, 13.0 meq/100g, 9.5 meq/100g, respectively. The Freundlich constant, K value, is 89.4, 26.9 and 9.25 for Namwon soil, Aewol soil and Mureung soil, respectively. The K value of Namwon soil with very high organic matter content and cation exchange capacity was the highest for Aewol soil and Mureung soil. The Freundlich constant, 1/n, show a high correlation with organic matter content, i.e., it is less than unity for organic matter rich soil of Namwon soil and greater than unity for organic matter poor soil of Mureung soil. The leaching of EPN is slower for Namwon soil with high K values, and faster for Mureung soil with low K values. The results of the study is demonstrated the potential of pollution for EPN have little leached into soil environment.
