“…By inference, the findings of this study are similar with the works of (Anani andOlomukoro, 2018 and2017;Aktar et al, 2010;Sundaray, 2009;Prasad et al, 2006), The geospatial analysis of these sites using the bullseyes commonly associated with inverse distance to a power interpolation ITRC; Interstate Technology and Regulatory Council (2016), indicated stations 2 and 3 as very high with value of 6.42, while stations 1 and 2 were considered as very low with a value of 1.4. The importance of this statement is that values that are closer to one another in space or time will be more alike than values that are far away from one another (Webster and Oliver, 2007).…”

“…The sandy, clayey, silt and other particles of the soil that settle down in the benthic region of a body of any aquatic ecosystem is termed sediment. Many authors like (Anani and Olomukoro, 2017;Bhardwaj et al, 2017;Olomukoro, 2017;Al-Taani et al, 2015;Bai et al, 2011;Chen et al, 2007;Adamo et al, 2005) have worked on the uptake of metals directly from the sediments, by benthic organisms, which in turn enhance the potential of some metals entering into the food chain and thus results in severe ecological and health risk conditions (Enuneku et al, 2018;Anani and olomukoro, 2018;2017).…”

The objectives of this study are to assess the trace and heavy metals pollution in the sediments of Ossiomo river, using geospatial mapping, environmetrics and ecological risk indices. The results from the descriptive statistics showed that there was significant difference (P<0.05) of the mean values of Fe, Mn, Cu, Cr, Cd, Pb, Ni and V. A posterior analysis using Duncan multiple regression analysis showed that stations 2 and 3 were significantly different from stations 1 and 4. While, there was no significant difference (P>0.05) in the mean values of Zn across the stations. The results of the relationship of the metals revealed a negative correlation between Fe and Mn with the other metals correspondingly. The results of the Kriging interpolation indicated a strong bull eye colour for stations 2 and 3 (6.42), while stations 1 and 4 were minimal (1.4). The results of the geospatial mapping indicated Fe, Zn and Mn to be the most dominant metals across the stations. The results of the PCA (principal component analysis) yielded 16 variables under 9 components with Eigenvalues >1 in components 1- 6 and these variables explained 99.99 % of the total variance in the sediment. The results of the degree of suitability and sphericity of the PCA revealed a high significant difference at P<0.001. The results of the potential ecological risk index values were very high in station 2 (824.30) and 3 (802.11) correspondingly. That of index of geo-accumulation was generally low (< 2). The findings from this study generally revealed the source apportionment of the trace and heavy metals to come from anthropogenic influences such as farming; fertilizers. Sustainable agriculture is highly recommended in order to reduce the impacts of anthropogenic activities, deterioration of the ecosystem and possible death of the life forms in this watercourse.

“…The cumulative study of the combined non-carcinogenic hazards of all metals ingested by the males however indicated a significant risk. Previous studies have shown that individual metals may synergize to elicit accumulative toxic effects 15,56 . These were corroborated by the current results which show that among the community dwellers, the adult males that often make contact with the river are most likely to exhibit non-carcinogenic symptoms.…”

“… 57 who observed that lead posed the greatest threat to human health among the analyzed trace metals in hair dye. Conversely, Anani and Olomukoro 56 enlisted cadmium and chromium as the leading causes of health hazards in Ossiomo River. Furthermore, they discovered greater health risks in children than adults exposed to Pb, Cd, and Cr in Ossiomo River in Edo State which is also within southern Nigeria; a location close to the current study area.…”

Oil exploration’s devastation on health and the environment may far outweigh its economic benefits. An oil spill occurred at Egbokodo River in Delta State, Nigeria, thereby polluting the land and water bodies. The study was therefore aimed at evaluating the impacts of iron, lead, cadmium, and chromium on the zooplankton community structure of Egbokodo River and the potential health risks. Zooplankton and surface water samples were collected to investigate the concentrations of trace metals and zooplankton abundance. The associated carcinogenic and non-carcinogenic effects of the metals in the water were analyzed. Trace metal concentrations in the surface water were determined using atomic absorption spectroscopy (Philips model PU 9100) and zooplankton samples were collected using a hydrobios plankton net (mesh size 25 µm). Total petroleum hydrocarbons (TPH) and oil and grease (OG) were determined using Agilent 7890B gas chromatography coupled to flame ionization detector (GC-FID) and volumetric analysis respectively. The trend of the abundance of zooplanktons cross the river was 18 individuals (Station A) < 100 individuals (Station B) < 155 individuals (Station C). Cyclopoida proved to be the most resilient to the impacts of the oil spill. On a taxa basis, the order of abundance among Calanoida, Cyclopoida, Cladoceran, and Harpacticoida was Station C > Station B > Station A, except in Amphipoda where Station B > Station C > Station A was observed. Iron and lead posed significant carcinogenic risks that are liable to be inflicted by the ingestion of the water. The cumulative non-carcinogenic health risk in the male was the only significant (> 1) among the age groups. Total petroleum hydrocarbons (TPH), oil and grease (OG), iron, and lead had notable impacts on the general abundance of zooplankton in the aquatic habitat. The dominance of the Cyclopoida in the river buttressed the impact of the oil spill which warrants a prompt remediation measure. The pollution had notable ecological impacts on the zooplankton community structure of the aquatic habitat. The adults in the nearby human populations are liable to elicit carcinogenic health challenges associated with lead and iron ingestion. The males are at risk of non-carcinogenic illnesses which are associated with the combined toxicity effects of all the metals. The study suggests that the pollution in Egbokodo River was validated by the dominance of the Cyclopoida in the aquatic habitat. The study confers bioindicator reputation on the Cyclopoida for future biomonitoring studies.
