喷气推进燃料-8(JP-8)是空军人员接触化学品的最大来源之一。尿萘酚已被建议为有用的生物标志物暴露于JP-8.MethodsMultivariate线性回归模型被应用于评估环境和工作相关因素的影响后,生产尿萘酚之间323 Air Force personnel.ResultsNaphthalene暴露,吸烟状况,及其相互作用,加上自我报告的皮肤刺激解释了约三分之二的萘酚水平的变化。暴露-吸烟相互作用与吸烟诱导萘和萘-1,2-氧化物(纳波)代谢中的一个或多个步骤一致。尿萘酚和萘暴露量之间存在超线性剂量反应关系。结论尿萘酚与JP-8的特定暴露源有关,包括吸入和皮肤接触。吸烟者和非吸烟者代谢萘在不同的速度,至少有两个代谢途径的诱导吸烟一致。Am.

BackgroundJet propulsion fuel‐8 (JP‐8) is one of the largest sources of chemical exposures among Air Force personnel. Urinary naphthols have been suggested as useful biomarkers of exposure to JP‐8.MethodsMultivariate linear regression models were applied to evaluate the effects of environmental and work‐related factors upon production of urinary naphthols among 323 Air Force personnel.ResultsNaphthalene exposure, smoking status, and their interaction, plus self‐reported skin irritation explained about two‐thirds of the variation in naphthol levels. The exposure‐smoking interaction was consistent with induction by smoking of one or more steps in the metabolism of naphthalene and naphthalene‐1,2‐oxide (NapO). A supralinear dose‐response relationship was observed between urinary naphthols and naphthalene exposure.ConclusionsUrinary naphthols were associated with specific sources of exposure to JP‐8, arising from both inhalation and dermal contact. Smokers and nonsmokers metabolized naphthalene at different rates, consistent with induction of at least two metabolic pathways by smoking. Am. J. Ind. Med. 46:234–244, 2004. © 2004 Wiley‐Liss, Inc.
