Synergetic effect of metals of electroplating industry effluent on physiology of the fish, Oreochromis mossambicus
P.S. NavarajP.G. Research Department of Zoology, Yadava College, Madurai, India
Abstract
The electroplating industry effluent is discharged indiscriminately in to
the environment with out proper treatment. This poses havoc to the water body, which could be
seen in the physiology and biochemistry of the chosen fish, Oreochromis mossambicus. The
metals strongly present in the electroplating effluent is chromium and nickel which is being tested
individually and collectively to assess its toxic nature. The intensity of the toxicity of synergetic
action of these metals is much stronger than individuai effect. The result is being noticed in
feeding budget and respiratory physiology of the fish, Oreochromis mossambicus. Ail parameters
of the feeding budget show a significant result in the synergetic effect of these metals.
Subsequently the respiratory rate and oxygen consumption of the fish in the stress medium is
highly affected by this combination. A serious threat is observed in the environment by these
metals and a proper treatment is suggested before releasing into the environment.
