Carps were kept in water containing 0.1,0.05 and 0.01 ppm of Pb, 0.05 ppm of Cd, or 15 and 1.5 ppm of Cr (VI) for 5 or 6 months, and the metal contents in the organs and tissues were determined. The carps in all groups exposed to the metals, except for 15 ppm Cr-group, appeared similarly to the control fish throughout the experiments. In Pb-groups, the Pb content of gills was much higher than those of kidney, viscera (hepatopancreas, digestive tract and gall-bladder), eye, muscle and skin, and the accumulation was kept even after 6 month. In fish exposed to 0.05 ppm-Cd, the metal was concentrated extremely and specifically in the kidney to give the concentration coefficient about 1600 after 5 month-exposure. The Cr was detected in various organs including kidney, hepatopancreas and gills, and the accumulation stopped within 3 months in 1.5 ppm Cr-group.
