metals were higher, indicating the importance of Fe in
the accumulation of element in sediments.
Although the results obtained showed that the metal
levels posed no danger to users of the water from this
estuary but the possibility of deleterious effects after
long period cannot be ruled out. This is because the
water body serves as the receptor for domestic and
industrial wastes as well as runoff from agricultural
land. Therefore, there is need to conserve the conditions of
the estuary in view of its uniqueness and the
importance of estuaries globally in the life cycle of
many aquatic species.
Authors' contributions
VIF designed, supervised and carry out the statistical
analysis. OUS collected the samples and did the
measurement. All authors read and approved the final
manuscript.
