PHYSIOLOGICAL EFFECTS OF LEAD ,CADMIUM AND THEIR MIXTURE ON SOME ORGANS OF Alburnus Mossulensis FISH

Alburnus mossulensis has been exposed to lead and cadmium for (96)h in order determination lethal concentration 50 (LC50) value. A total of 140 fish used this experiment divided into two groups each group contain 70 fishes .The first exposure pbcl2 while the second cdcl2. Method Finney Probit Analysis analysis data. LC50 value PbCl2 CdCl2 was (57.8 29.6) mg/l respectively. Then about 200 4 groups, 1/2LC50 ,the third contained (1/2LC50 PbCl2+1/2LC50 CdCl2) as so control peroids (1,4,7 14) days level antioxidants Glutathione (GSH) lipid peroxidation (Malondialdehyde MDA) . The testes were carried out three replications, ,cadmium their mixture induced oxidative stress results study explained significant decrease increase (Tukey test, P˂0.05) Malondialdehye compared with all treatments It is possible conclude that Cadmium have cytotoxic effects, Fish mortality rates increasing concentrations periods.
