在日本茨木县神栖市的井水中检测到了二苯胂酸（DPAA）和苯胂酸（PAA），这两种物质是用作催吐气体的有机砷化学战剂的降解产物。为了测定井水中的有机砷化合物，以砷酸水溶液和苯肼为原料合成了DPAA标准物质。DPAA显示质子化。通过电喷雾电离飞行时间质谱法，在m/z 263 [M+H]（+）处的质子化离子中损失H2O离子，在m/z 245 [M+H-H2O]（+）处损失H2O离子。采用高效液相色谱-电感耦合等离子体质谱联用技术对DPAA和PAA进行了定量分析，该系统对井水等清澈液体样品的分析效果良好。版权所有（C）2005 John Wiley Sons，Ltd。
Diphenylarsinic acid (DPAA) and phenylarsonic acid (PAA), which were degradation products of organoarsenic chemical warfare agents used as sternutatory gas, were detected in the well water at Kamisu, Ibaraki Prefecture, Japan. The standard material of DPAA was synthesized with aqueous arsenic acid and phenylhydrazine in order to determine organic arsenic compounds in well water. The DPAA showed a protonated. ion at m/z 263 [M+H](+) and a loss of H2O ion at m/z 245 [M+H-H2O](+) from protonated ion by the electrospray ionization time-of-flight mass spectrometry. The quantitative analysis of DPAA and PAA was performed by high-performance liquid chromatography inductively coupled plasma mass spectrometry and the system worked well for limpid liquid samples such as well water.
