激光诱导击穿光谱（LIBS）用于检测溢油污染土壤（OSCS）中的有毒金属。 OSCS 样本是从 1991 年海湾战争中遭受石油泄漏的波斯湾沿岸的沙特阿拉伯库尔萨尼亚采集的。从受污染的土壤中检测到了铝、镁、钙、铬、钛、锶、铁、钡、钠、钾、锆和钒等对环境重要的元素。研究了分析的最佳实验条件。 LIBS 系统使用含有这些微量元素的标准样品进行校准。将使用激光诱导击穿光谱 (LIBS) 获得的结果与使用电感耦合等离子体发射光谱 (ICP) 获得的结果进行比较。某些元素（Ba 和 Cr）的浓度被发现高于允许的安全限值。还讨论了与接触此类有毒元素相关的健康风险。
Laser-induced breakdown spectroscopy (LIBS) was applied for the detection of toxic metals in oil spill contaminated soil (OSCS). The OSCS samples were collected from Khursania Saudi Arabia along the coast of Persian Gulf exposed to oil spills in 1991 Gulf war. Environmentally important elements like Aluminum Magnesium, Calcium, Chromium, Titanium, Strontium, Iron, Barium, Sodium, potassium, Zirconium and Vanadium from the contaminated soil have been detected. Optimal experimental conditions for analysis were investigated. The LIBS system was calibrated using standard samples containing these trace elements. The results obtained using Laser-Induced Breakdown Spectroscopy (LIBS) were compared with the results obtained using Inductively Coupled Plasma Emission Spectroscopy (ICP). The concentrations of some elements (Ba and Cr) were found higher than permissible safe limits. Health risks associated with exposure to such toxic elements are also discussed.
