MULTI-CONTAMINANT POLLUTION BURDEN IN NIGERIAN FRESHWATER ECOSYSTEMS: A SYSTEMATIC REVIEW OF ECOTOXICOLOGICAL EVIDENCE FROM HEAVY METALS, HYDROCARBONS, PESTICIDES, AND MICROPLASTICS FOR INTEGRATED RISK ASSESSMENT
Nigerian freshwater ecosystems are subjected to multiple exposures of heavy metals, petroleum hydrocarbons, organochlorine and organophosphate pesticides and microplastics. This co-exposure makes risk assessment of contaminants alone more complex and underestimates the combined ecological exposure and impact on aquatic...
