Trace and minor element content of Macondo crude oil

Crude oil is typically enriched in vanadium and nickel. Our objective is to determine if metal enrichment, including V or Ni, in oil contaminated marine sediments and beach sands can be an effective proxy for mapping oil contamination. Crude oil from the Macondo well was digested and analyzed via ICP-MS. Our analyses show V, Ni, Cu and Co concentrations of 0.77 ppm, 1.94 ppm, 130ppb, and 60 ppb, respectively.原油通常富含钒（Vanadium）与镍（Nickel）。本研究旨在验证石油污染海洋沉积物及海滩砂中的金属富集（包括钒或镍）能否作为有效的石油污染测绘代用指标。马孔多（Macondo）油井产出的原油经消解处理后，通过电感耦合等离子体质谱法（ICP-MS）进行分析。本次分析结果显示，钒（V）、镍（Ni）、铜（Copper）及钴（Cobalt）的浓度分别为0.77 ppm、1.94 ppm、130 ppb与60 ppb。
