The study of water quality of three rivers and three lakes selected throughout the country was carried out in June, August, December, 1979 and April 1980. Although trace amounts of Hg, Cd, and Cr (VI) were detected in some areas and certain seasons the waters in these areas were found to be good in quality. Moreover, organochlorine pesticides but BHC which was turned out to be dissolved in the waters within 0.05 ppb were not detected at all. Grains collected from several places contained Hg and Cd in the rage of 0.036-0.094 ppm and ND-0.5ppb respectively. In the analysis of grains for organochlorine pesticide residues, the amount of total BHC were within 0.01 ppm and other organochlorine pesticides including heptachlor were not detected. The amounts of heavy metals and pesticide residues in several grains were not affected by kinds of grains and production areas. The heavy metals in fresh fishes were determined as well and they were found to be within allowable limits.
