the capability of copper sulfate (CuSO4) and lead acetate (CHCOO)3
Pb in inducing chromosomal aberrations in aquatic organisms. To achieve
such a purpose, Oreochromis niloticus was chosen as a test material for
the study. The LC50 of the two chemicals was determined and
the data indicated that LC50 of copper sulfate (CuSO4)
and lead acetate (CHCOO)3 Pb were 40.6 and 422.5 mg L-1,
respectively. The effect of both chemicals on fish chromosomes and mitotic
indices was investigated and the results revealed that gill cells of the
treated fish by copper sulfate and lead acetate displayed lower mitotic
activity than that of the control group, both pollutants were found to
be positive inducer of macro-DNA damage which represented by different
types of aberrations e.g., chromatid deletions, chromatid breaks, gaps,
fragments, stickness, translocations, ring chromosomes and centromeric
attenuation. We also observed that chromatid deletion, stickness and fragments
were more frequent than other chromosomal aberrations.]]>Barsiene, J., R. Bucinskiene and K. Joksas,20022002Bertolla, L.A.C., C.S. Takahashi and O.
