The present study suggested in order to explore the
capability of two environmental pollutants namely copper sulfate (CuSO4)
and lead acetate (CHCOO)3 Pb to induce histopathological changes
and changes in the electrophoretic pattern of serum proteins in aquatic
organisms. To achieve such a purpose, Oreochromis nilotica were
chosen as a test material for the study. After determination of LC50
of both pollutants, fish were treated with 1/5, 1/10 and 1/20 of LC50
of either CuSO4 or (CHCOO)3 Pb for a periods of
2, 4 and 6 weeks. The histopathological studies revealed that both chemicals
under study are capable of inducing changes in different fish organs (gills,
liver, kidneys and spleen) after 2 and 6 weeks of treatment and at three
different concentrations. These histopathological changes were positively
correlated in its effects with the increase of pollutants concentration
and time of exposure. Concerning the electrophoretic patterns. The control
samples exhibited 12 bands with different densities and intensities. The
total number of bands were 11, 16 and 5-13 bands after exposure to 1st,
2nd and 3rd concentrations of copper sulfate, respectively. The total
number of bands were ranged from 8-17, from 9-13 and from 9-12 bands after
exposure to 1st, 2nd and 3rd concentrations of lead acetate respectively. |
