Environmental Health Status and Aqua-Economic of Some Aquatic Ecosystems in Badagry Division, Lagos State, Southwest, Nigeria
The study examined the heavy metals contents,
physicochemical and biological characteristics (such as growth parameter of
some fish and its histopathology) from four aquatic ecosystems (Gbaji, Topo,
Ajegunle, and Agboju) in the Badagry Division of Lagos State. Samples were
collected and analyzed using standard methods. Data were analyzed via analysis
of variance, descriptive statistics, indices such as enrichment factor(EF),
ecological risk factor(Er), contamination factor(CF), hazard index(HI) as well
as modeling using mathematical algorithm. Results showed that Ajegunle water
bodies were the most polluted and least economically viable. However, majority
of the physicochemical examined in all the stations were within WHO permissible
limits. There were significant differences in physicochemical and biological characteristics across the sampling
stations. The indexes indicated that rate of pollution was Ajegunle> Agboju>
Gbaji> Topo. The modeling indicated that if pollution rate are not
minimized, over 50% of values of physicochemical in Ajegunle and Agboju will
exceed WHO permissible in the next 5 years. In relation to the hectares as a
proportion of ecological services rendered by the sampled aquatic stations, the
trend of productivity was Topo>Gbaji>Agboju> Ajegunle. The study
concluded that all users of these aquatic ecosystems must ensure good
management of the habitat so as to conserve its biodiversity as well as its
ecological services.
