In this paper, swabbings from various public areas in 28 different cities throughout the United States were collected. A wide variety of objects were tested, ranging from park benches and telephones to sign posts and mailboxes. Inorganic anions and cations common in low explosives were detected simultaneously using capillary zone electrophoresis. Organic high explosives including nitroaromatics, nitramines, and nitrate esters were detected using gas chromatography with a pulsed-discharge electron capture detector. Confirmation of selected results was performed by ion chromatography and negative ion chemical ionization GC/MS. In general the results provide two major conclusions: (i) with the exception of nitrate, most low explosive oxidizers are rare in the environment; (ii) no organic explosives or significant interferences to these explosives were detected.
在本文中，采集了美国28个不同城市各个公共场所的擦拭样本。测试了各种各样的物品，从公园长椅、电话到路标和邮箱。使用毛细管区带电泳同时检测低爆炸物中常见的无机阴离子和阳离子。使用配备脉冲放电电子捕获检测器的气相色谱法检测包括硝基芳烃、硝胺和硝酸酯在内的有机高爆炸物。通过离子色谱法和负离子化学电离气相色谱/质谱法对选定结果进行确认。总体而言，结果得出两个主要结论：（i）除硝酸盐外，大多数低爆炸物氧化剂在环境中很少见；（ii）未检测到有机爆炸物或对这些爆炸物的重大干扰。
