“…On the other hand, ecological risk (Er) factor were low as the value were all Er <40 Table 5. Similar results were obtained by Horsfall and Spiff, (2002), Emoyan et al (2006) and Kpee and Ekpete (2014), while elevated levels were reported by Bryan (1976) and Depledge (1987). The mean concentration of Cu in Sombriero River system followed a different trend where highest mean concentration of Cu was obtained in June.…”

“…The elevated concentration of Cd in September may result from the fact that in the rainy season, more waste and effluents are carried in drains to the stream. The results obtained in this study is higher than the findings of Horsfall and Spiff (2002); Kpee and Ekpete, (2014), where they reported low levels of Cd in sediment of New Calabar River. The sources of cadmium to the Ipo stream is mostly from pigments, plastics, coated fabrics, textiles, rubber, paints and erosion or run-offs from farmland where phosphate fertilizer was applied to crops.…”

“…The lowest and highest mean values obtained are 0.94±0.21 and 2.35±0.63mg/Kg for Werri and Barawansah respectively. When the magnitudes of copper in this assessment were compared with other literatures on sediments in Niger Delta region, it was observed that the values were lower than those observed in sediments from Bodo creeks, Owan River, and Andoni River respectively [50,59,62]. But the mean value is higher than those from Orashi River [63].…”

Ecological Risk Assessments are executed to appraise the probability of adverse ecological effects occurring as a consequence of exposure to biological, physical, or chemical factors that causes hostile responses in the environment. Several studies have shown extensive heavy metals and crude oil contamination of soils, sediments, rivers, creeks, and ground waters in Ogoniland, Nigeria. However, the Sogho Community in Ogoniland has not been studied. Hence, this paper evaluates the distribution and ecological risk assessment of heavy metals in riverine sediments of Maa-Dee-Tai River in Sogho Community, Ogoniland, Rivers State, Nigeria using Solaar Thermo Elemental Atomic Absorption Spectrophotometer, Model SN-SG 710960 after total dissolution of riverine sediments by hydrofluoric acid (HF) and aqua regia (HNO 3 : HCl; 1:3, v/v) at a temperature of 100 o C. Distribution of heavy metals in the sampling stations reveal that Werri had the maximum magnitude of nickel (Ni) among the three stations assessed and the mean value for the three stations is 4.21±0.92mg/Kg. The average values recorded for Ni in the three stations were; 3.52±0.58, 4.04±1.04 and 5.07±1.14mg/Kg for Dee-Tai, Barawansah and Werri respectively. The average mean concentration of the sampling stations for each metal (mg/kg) are Ni (4.21), Zn (3.56) Cr (3.35), Pb (3.25), Cu (1.59), Co (0.8), As (0.12) and Cd (0.12). The order of abundance of the metals in the riverine sediments is Ni>Zn>Cr>Pb>Cu>Co>As>Cd. In all the stations examined, Nickel (Ni) was the most abundant metal. The pollution indices revealed that the river was unpolluted with the different heavy metals studied. The potential environmental risks assessment of heavy metals in riverine sediments of the Maa-Dee-Tai River in Sogho Community, Ogoniland reveals that the river poses low risks in terms of pollutants with reference to heavy metals in the sediment. Hence, it is necessary to preserve the natural state of the river.

“…Aquatic flora and fauna are always in continuous contact with water, which implies that they are directly affected by any change in water quality. Over exploitation and exploration of the natural environment without recourse to laid down rules or principles results in the deposition of toxic substances in the ecosystem [3]. Contaminants which originated from agricultural waste, factory discharge channels and Silver River, Southern Ijaw, Bayelsa State, Niger Delta, Nigeria effluents sources are discharged into the environment, which enhances or increases the total contaminant burden of the receiving environment (whether aquatic or terrestrial).…”

Water and sediment samples were collected from Silver River to determine the levels of various physicochemical parameters in both sediment and water from the river. This research was conducted with the aim of determining the extent of deterioration of the river as a result of artisanal refining of crude oil. The result obtained showed that the mean values of the different parameters examined in the water were; conductivity (26,567±464.28 µS/cm), total dissolved solids (TDS), (13,250±187.08 mg/L), total suspended solids (TSS), (17.78±3.07 mg/L), turbidity (15.57±2.45 NTU), pH (7.12±0.03), salinity (8766.67±449.69 mg/L), total hydrocarbon content (THC) (45.43±3.86 mg/L), nitrates (NO 3 -), (4.93±0.61 mg/L), sulphates (SO 4 2-) (1471.07±1058.43 mg/L), phosphates (PO 4 3 ), (0.64±0.16 mg/L), dissolved oxygen (DO), (4.73±0.57 mg/L), biochemical oxygen demand (BOD), (33.20±2.33 mg/L) and chemical oxygen demand (COD), (50.13±3.21 mg/L). Physicochemical parameters such as conductivity, TDS, salinity, THC, SO 4 2-, DO, BOD and COD fall below the standard requirement for domestic water consumption, while TSS, turbidity, pH, NO 3 and PO 4 3were within the acceptable range for drinking water by WHO. The mean values of sediment physicochemical parameters were; pH (7.20±0.03), conductivity (16701.67±513.65 µS/cm), total organic carbon (TOC) (2.37±0.05%) and total organic matter (TOM) (4.09±0.09%). The particle size examination showed that clay was 7.33±1.25%, silt (14.67±1.25%) and sand (78.00±1.63%). The examined sediment nutrient species showed that the mean values were 0.51±0.01, 8.81±12.09 and 0.27±0.01mg/kg for NO 3 -, SO 4 2and PO 4 3respectively. The findings of this work showed that the silver river (both water and sediment) are under human influence which not handled in the immediate, can in the near future constitute a major health risk to the entire environment.
