采用原子吸收分光光度计对尼日利亚三角洲州瓦里河地表水样品中镉、铬、铜、铁、铅、锰、镍、钒和锌九种重金属的浓度进行定量分析。铁 (Fe) 的平均浓度最高，为 1.9304mgl-1，而铅 (Pb) 的平均浓度最低，为 0.0001mgl-1。瓦里河接收来自工业、农业和生活的污水。镉、铬、锰和镍的浓度高于饮用水标准指南中的值，表明存在对公共健康的风险。因此，有必要对地表水中的重金属浓度进行持续监测，并由相关组织开展全面的保护工作。
Surface water samples from Warri river in Delta State of Nigeria were analyzed quantitatively for the concentration of nine heavy metals, namely: Cadmium, Chromium, Copper, Iron, Lead, Manganese, Nickel, Vanadium and Zinc, using Atomic Absorption Spectrophotometer. Iron (Fe) recorded the highest mean value of 1.9304mgl-1 while Lead (Pb), had the least mean concentration of 0.0001mgl-1. Warri river receives effluents from industrial, agricultural and domestic sources. Cadmium, Chromium, Manganese and Nickel had higher concentrations than values in standard guidelines for potable water, pointing to the existence of risks to public health. There is need, therefore for a constant monitoring of the heavy metals concentrations in the surface water as well as a comprehensive conservation efforts by relevant organizations.
