Abstract

OBJECTIVES

We studied the impact of clean indoor air law exemptions and preemption policies on the prevalence of a tobacco-specific lung carcinogen-4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)--among nonsmoking bar and restaurant workers.

METHODS

secondhand smoke were compared with results from participants who were exposed to it.

RESULTS

Participants exposed to workplace secondhand smoke were more likely to have any detectable level of NNAL (P=.005) and higher mean levels of NNAL (P < .001) compared with nonexposed participants. Increased levels of NNAL were also associated with hours of a single workplace exposure (P=.005).

CONCLUSIONS

Nonsmoking employees left unprotected from workplace secondhand smoke exposure had elevated levels of a tobacco-specific carcinogen in their bodies. All workers--including bar and restaurant workers--should be protected from indoor workplace exposure to cancer-causing secondhand smoke.

摘要

目的

我们研究了室内空气清洁法豁免条款和优先适用政策对非吸烟酒吧和餐厅员工体内一种特定于烟草的肺部致癌物——4-(甲基亚硝胺基)-1-(3-吡啶基)-1-丁酮(NNK)——流行率的影响。

方法

将接触二手烟者的结果与未接触二手烟者的结果进行比较。

结果

与未接触二手烟的参与者相比,接触工作场所二手烟的参与者更有可能检测到任何水平的NNAL(P = 0.005),且NNAL的平均水平更高(P < 0.001)。NNAL水平的升高也与在单一工作场所接触的时长有关(P = 0.005)。

结论

未受保护免受工作场所二手烟暴露的非吸烟员工体内一种特定于烟草的致癌物水平升高。所有工人——包括酒吧和餐厅员工——都应受到保护,使其免受工作场所室内致癌二手烟的暴露。
