“…The concentration of cadmium in the soil sample used was above maximum permissible limit (MPL) (0.6 mg/Kg) (SEPA, 1995). Voogt et. al., (1980) upheld that Cd can be taken up by plant such as maize, spinach, wheat and rice.…”

The demand and utilization of petroleum products have re-energized its exploration and exploitation globally and this upsurge in world production, refining and distribution of petroleum products have brought with it various problems of environmental pollution, which have effects on the ecosystems. Twenty (24) polyethylene pots each containing 7 kg of sandy loam soil mixed with 50 ml of crude oil, were arranged in the Botanical garden of the University of Ilorin, Nigeria, to assess their ability to phytoextract heavy metals in Crude oil-polluted soil. Seeds of Amaranthus hybridus L., Tithonia diversifolia, Abelmoschus esculentus L. and Zea mays were sown in polyethylene containers containing 7 kg of contaminated or Control soil. The containers were arranged in a complete randomized design. Plants were left to grow for two months with regular watering. Plants were harvested, separated into roots and shoots and oven-dried to constant weight. The experimental plants have been able to reduce the concentration of Cu in both soils by about 45% to 85%, Cr in the soil by 92.08% to 96.72%, as the residual concentration varied between 66.00 mg/kg and 99.00 mg/kg, Cd in the soil was reduced to 4.00 mg/kg and 17 mg/kg which represented 96.8% and 86.4% reduction. Tithonia had the highest Pb reduction in crude oilpolluted soil. Ni concentration was reduced by 85.84% by Tithonia planted in crude oil-polluted soil, 94.59% by Amaranthus hybridus planted in Control soil. These show that all the test plants were good phytoextractors of the metals.

“…The Akani Obio Uruan River is indeed highly polluted as a result of incessant disposal of wastes such as human faeces, petroleum products from engine boats, and all forms wastes from markets, shops and surface water runoff. It is an established fact that sediment is a major sink for metals in aquatic environment [11]. Since winkles feed on the sediment, they stand a high risk of exposure to these toxic metals.…”

The levels of some trace metals (Cd, Cr, Cu, Pb and Zn) were quantified in water, sediment and two species of winkles (Pachymelania bryonensis and Pachymelania fusca mutans) in Akani Obio Uruan River from August to September 2018 (wet season) and February to March 2019 (dry season), using Varian spectra 100 atomic absorption spectrophotometer. The levels of some physicochemical parameters (temperature, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), electrical conductivity (EC), total dissolved solid (TDS), nitrate, sulphate and phosphate) were equally quantified in water. From the results, Cd level of 0.088 mg/l in water was higher than those of the other trace metals investigated. Accordingly, Cu level of 0.602 mg/kg in sediment was higher than 0.017 mg/kg in water and 0.077 mg/kg in one species of the winkles. Zn level of 0.141 mg/kg in one species of the winkles was higher than those of the other metals. In general, the levels of most of the metals were higher in all the samples during the wet season. This could be attributed to excessive water runoff during the wet season which could have resulted to the leaching of various kinds of wastes into the water bodies. Interestingly, the levels of all the trace metals investigated in all the samples were below the maximum acceptable limits stipulated by WHO and the US environmental protection agency (USEPA). Physicochemical examination revealed that the levels of pH, temperature, TDS, EC, nitrate and sulphate were below the maximum permissible limits set by WHO. The levels of DO and phosphate in the water were however higher. This may have deleterious effect on aquatic ecosystem and the health of the rural dwellers that consumed the winkles and use the river water directly for domestic purposes without treatment.

“…These metals are essential to human life within permissible limits. Toxicity of metal ions such as nickel, copper, zinc and cadmium in human beings is as follows: kidneys and liver [15]. Teratogenic properties have been shown [16] whereas carcinogenic properties are suspected [17][18][19].…”

Synthetic resin, Amberlite XAD-4 was linked covalently with the third generation supramolecule, octa-O-methoxy resorcin [4] arene through -N=N-group to form chelating resin, which has been characterized and effectively used for the separation and preconcentration of metal ions such as Ni(II), Cu(II), Zn(II) and Cd(II). Critical parameters such as pH, flow rate, sorption capacity, breakthrough studies, distribution coefficient, preconcentration factor, concentration of eluting agents responsible for quantitative extraction of metal ions were optimized. The synthesized resin showed good binding affinity towards Ni(II), Cu(II), Zn(II) and Cd(II) under selective pH conditions. Good breakthrough capacity and fast exchange kinetics of the resin lead to effective separation of metal ions from their binary and ternary mixture by column method on the basis of pH and eluting agents. The resin could be reused for about 8 -10 cycles. The proposed method having the analytical data with the relative standard deviation (RSD) < 2% and with recoveries of analytes higher than 98%, reflects upon the reproducibility and reliability of the method which has been successfully applied in the separation and determination of Ni(II), Cu(II), Zn(II) and Cd(II) ions in synthetic, natural and ground water samples.
