More than 2·7 million US military servicemen and women have served in Afghanistan, Iraq, and surrounding countries since 2001, where they encountered a range of complex respiratory exposures. Among other exposures, more than 80 open-air US military burn pits in Afghanistan and Iraq were used to incinerate hundreds of metric tons of garbage each day. JP-8 jet fuel and diesel that includes naphthalene and other organic compounds were used to keep the fires burning. With housing barracks as close as 30 m from these fires, military personnel and contractors were exposed around the clock to dark plumes of toxic smoke containing benzene, formaldehyde, arsenic, and other chemicals.

美国胸科协会呼吁对军事部署中的呼吸道暴露进行更多的研究。

自2001年以来，已有超过2·700万美国军人在阿富汗，伊拉克和周边国家服役，他们在那里经历了一系列复杂的呼吸道暴露。除其他暴露外，每天有80多个美军在阿富汗和伊拉克的露天焚烧炉被用来焚化数百公吨的垃圾。包含萘和其他有机化合物的JP-8喷气燃料和柴油被用来防止大火燃烧。由于房屋营房距离这些火灾只有30 m，军事人员和承包商日以继夜地暴露在深色的有毒烟雾中，这些烟雾中含有苯，甲醛，砷和其他化学物质。
