We have investigated the usefulness of elemental analysis by energy-dispersive X-ray spectroscopy (EDX) in the examination of free liquid from the sphenoid sinus of drowning victims. We detected both chlorine and bromine in liquid taken from the sphenoid sinus of seawater drowning victims. Because these elements were below the quantification limit in freshwater cases, we could easily distinguish seawater from freshwater drowning cases. Detection of these elements from the liquid in the sphenoid sinuses of drowning victims may be useful as a supportive measure for seawater drowning.
我们研究了能量色散X射线光谱法（EDX）元素分析在溺水受害者蝶窦游离液体检查中的实用性。我们在海水溺水受害者蝶窦采集的液体中检测到了氯和溴。由于在淡水溺水案例中这些元素低于定量限，我们能够轻松区分海水溺水和淡水溺水案例。从溺水受害者蝶窦液体中检测这些元素，可能作为海水溺水的一种辅助检测手段。
