The uptake and distribution of mercury is selected tissue of goldfish (Carassius auratus) from low-level mercury contaminated water were determined. The mercury concentration was 5 ppb and tissue analyzed were liver, kidney and muscle. Goldfish accumulate mercury from low-level mercury concentration in water. The whole body mercury increase in the fish was from 0.07 to 1.3 ppm. The selected tissues (kidney, liver and muscle) showed accumulations from 3 to 14 ppm, 1 to 10 ppm and 0.06 to 1.2 ppm respectively. The mercury in the water demonstrated a cyclic nature from the inorganic form to organic form and back. Mercury was also rapidly lost from the aquatic system and the water had to be continually monitored to determine the amount of mercury to be added to maintain the 5 ppb level.
