The effect of Environmental Pollution on some biochemical parameters in earthworms

he effect of environmental pollution on the activities
of aldehyde oxidase (AO), superoxide dismutase (SOD),
catalase (CAT) and levels of ascorbic acid (AA) and lipid
peroxidation (LPO) in earthworms
(Esienia fetida Andrei)
,
was studied in three highly polluted locations (Refinery road,
Okere market and PTI round-about) in Warri, an Industrial
town in the Niger-Delta region of Nigeria, relative to Abraka,
a less industrialized town in the same region, which was used
as a control study point. TheMean ± SD values of AO activities
(μmole benzoate / ml) were 0.011 ± 0.0012 for Refinery
road, 0.0080 ± 0.002 for Okere market area, 0.0058 ± 0.0013
for PTI round-about area and 0.0022 ± 0.00009 for Abraka
study location. The results obtained for SOD activity (Units
/ g wet tissue) were 24.00 ± 3.80 for Refinery road, 12.00
± 2.80 for Okere market, 16.00 ± 4.62 for PTI round-about
and 5.60 ± 2.50 in Abraka town. For CAT activities (K min-1),
the Mean ± SD values were 0.98 ± 0.0134 for Refinery road,
1.08 ± 0.061 for Okere market, 0.95 ± 0.018 for PTI round-
about and 0.93 ± 0.0125 for Abraka. AA concentrations in
earthworms from Refinery road, Okere market, PTI round-
about and Abraka were 0.175 ± 0.0172, 0.118 ± 0.0148,
0.109 ± 0.014 and 0.072 ± 0.0040 mg / ml respectively. The
values for LPO (μmole / ml) for Refinery road, Okere market,
PTI roundabout and Abraka were also 5.83 ± 0.46, 4.04 ±
0.58, 4.25 ± 0.48 and 2.09 ± 0.43 respectively. After statistical
analysis, the foregoing results indicate that the levels of AO,
SOD, AA and LPO but not CAT were significantly higher in
Warri area relative to Abraka. The results obtained suggest
that elevation of these parameters in earthworms can be
used as bioindicator of pollution.
Speaker Biography
Asagba Samuel Ogheneovo is a Nigerian by birth. He is an alumnus of the University
of Benin, Nigeria, where he obtained his
B.Sc. and PhD degrees in Biochemistry. He
obtained his
M.Sc. degree in the same subject from the University of Lagos, Lagos
Nigeria. He is highly interested in academic research, which informed his decision
to pick up an academic position with Delta State University in 1994 where he has
remained till date. He has been a Professor of Biochemistry, since October, 2010 and
his current research interest is in Molecular aspects of heavy metal toxicity.
