Abstract
The oil palm is an economic crop that has gained worldwide recognition due to its importance. Produce such as the stem, fruits, and leaves contain phytonutrients and antioxidants that are mediators of cellular functions and a cure for various ailments. The oil palm plantations receive inputs of elements from natural and anthropogenic sources. However, while some of the elements are beneficial, they may be toxic at high concentrations. The quality of ground water is important due to the possible uptake of trace and major elements by the oil palm. In this study, the concentrations of fifteen elements in ground water from oil palm plantations in southern Nigeria were measured. The inductively coupled plasma optical emission spectrometer (ICP-OES) was the instrument of choice because of its multielemental capabilities. The study revealed that of the trace elements, the highest concentrations were obtained for lead (Pb) (0.090–10.29 mg/L), while the lowest concentrations were obtained for cadmium (Cd) (0.119–0.391 mg/L). The concentration of the metals were compared with water quality standards established by the World Health Organization in 2011.
