Survey was made of sea water pollution along the seashore of Kei-Yo industrial area (Chiba prefecture) for the 12 years, 1965 to 1976. The values of chemical oxygen demand (COD), NH_4-N, and NO_2-N were examined with the lapse of time. The peak of COD value was found from 1971 to 1973,and then the value showed the tendency to decrease a little. The value of NH_4-N at Station 1 and Station 2 tended to increase remarkably from 1965 to 1976,and thereafter, to reach a plateau. The value of NO_2-N at Station 1,Station 2,Station 3,and Station 7 showed the tendency to increase slowly from 1965 to 1976.
