Arsenic accumulation in organs of the fresh water fish Tribolodon hakonensis.
The fish Tribolodon hakonensis lives in good health in Lake Usoriko, which has been acidified and naturally contaminated with arsenic by volcanic activities. We have determined the contents of various metals in various fish organs of T. hakonensis, collected at Lake Usoriko. We found that a large amount of arsenic was accumulated in the eye, especially in the choroid-retina part. The arsenic concentrations in the liver and kidneys were about 0.4 microgram/g (wet), whereas the muscle contained less arsenic. The arsenic accumulation in the skin was also observed, especially in the epaxial part. Zinc and arsenic contents in various fish organs correlated well.
