“…Generally, all the machineries used for processing were run on leaded petrol/diesel and could be a contributory factor of high lead concentrations on the oil palm plantations. Similar studies on soils sampled on the oil plantations have shown that lead is a potentially mobile element and soluble in soil water and under acidic conditions of the soil, it becomes mobile and can bio-accumulate in the palm fruit (Yasmin et al, 2000;Olafisoye et al, 2013;Olafisoye et al, 2014). A recent study on the bioavailability and accessibility of metallic elements in the soil on the oil palm plantations revealed the environmental quality of manganese in soil solution (Olafisoye et al, 2016).…”

“…Such industries include the paint industries, leaded petrol or gasolines servicing and drilling industries, coal burning and metal smelting industry, lead cell battery industry, lead mines, lead paints and plumbing industries. Concentration of lead in the environment could also be from anthropogenic sources such as the exhaust pipes of vehicles or machines being ran on leaded petrol and electronic waste such as leaded batteries(Chibuike and Obiora, 2014;Olafisoye et al, 2014;Anju and Banarjee,…”

This study evaluated the quantitation of synthetic phenolic antioxidants and trace elements in virgin palm oil. A Reverse Phase High Performance Liquid Chromatography coupled with Ultra Violet Visible detection spectrophotometry was employed for the analysis of synthetic antioxidants. The synthetic antioxidants studied were Butylatedhydroxyanisole (BHA), Butylatedhydroxytoluene (BHT), 2-ethylhexyl 4 methoxycinnamate (EEMC) and Propyl gallate (PG). A proposed ICP-OES using oilwater micro emulsion as sample preparation method was used for metallic element analysis because it is not only reproducible, accurate and reliable but also convenient because it provided a sample extraction capable of breaking down the complex matrix in virgin palm oil. The limits of detection for BHA, BHT, EEMC and PG were found to be 0.041, 0.057, 0.06 and 0.03 mg/L respectively while the limits of quantification values were 0.56, 0.49, 0.05 and 0.04 mg/L respectively. None of the synthetic antioxidants was detected in the samples studied. This was an indication that local farmers probably preserved the oil samples prior to storage by traditional methods. The elemental analysis of virgin palm oil is necessary to decide if the oil is suitable for food, fuel or raw materials for the chemical industry. The concentrations of metallic elements found in the oil samples analysed in this study ranged between 0.006 mg/kg in Ubiaja plantation and 161.576 mg/kg in Benin City plantation respectively. Tin recorded high concentration in Benin City plantation and Pb a low concentration in Ubiaja plantation. The concentrations of metallic elements were rather high in most samples hence the oil is best suitable for use as raw material for the chemical industry. It can therefore be concluded that the level of environmental pollution on the plantation be eradicated or reduced to the barest minimum to improve the quality of the virgin palm oil for human consumption.
