Abstract
The effect of chronic exposure to petroleum hydrocarbon (PHC) pollution on the
concentrations of glucose, serum and liver malondialdehyde (MDA), protein carbonyl and
the histology of liver tissues of the native fowl (Gallus domesticus) from Egbema in the
Niger Delta Area (NDA) was studied. Identical fowls from an unpolluted area of Mbaise
served as the control. Results showed no significant difference (P<0.05) in the mean
glucose concentration obtained for fowls from both environments. The values obtained for
serum and liver MDA and protein carbonyl for the test and control fowls were found to be
significantly (P<0.05) different. There were elevated concentrations of MDA, protein
carbonyl in the serum as well as MDA from liver homogenates of fowls from Egbema
when compared to those of fowls from Mbaise. Histological changes were also observed
in the liver sections of fowls from Egbema as against none in the liver sections of fowls
from Mbaise. These changes were characteristically necrotic and inflammatory. Thus, the
findings from this study show, in clear terms, that PHC pollution (crude oil and gas flaring)
markedly affected the Egbema environment and induced changes in tissues of the native
fowl whose nativity and ancestry are from there.
