This book describes the bioconcentration and distribution of zinc on the selected organs of fresh water fish Labeo rohita. The bio-concentration pattern in the different organs reveals that the liver is the prime site of metal binding and muscle accumulates least metal concentration. It has also been observed that the administration of chelating agent D-Penicillamine reduces the zinc concentration in all tissues more effectively than the administration of the chelating agent Ethylene Diamine Tetra Acetic acid. Further, this work extended to study the effect of zinc exposure on the...
