To measure secondhand smoke levels in workplaces in Guatemala and to compare exposure to levels in other Latin American cities.
Exposure was estimated by passive sampling of vapor phase nicotine using a filter badge. Filters were placed in 1 hospital, 1 school, 2 universities, 1 government building, the airport, and 10 restaurants/bars. In total, 103 filters were deployed (plus 7 duplicates and 10 blanks). Nicotine (microg/m(3)) was measured by gas chromatography. Medians [interquartile ranges (IQR)] of nicotine concentrations were reported and compared with other Latin American cities. A survey about attitudes for smoke-free workplaces was distributed among employees.
Nicotine was detected in most (68%) locations surveyed (including workplaces where smoking is banned). The highest levels were found in bars [median, 4.58 microg/m(3) (IQR, 1.71-6.44)] and restaurants [median, 0.56 microg/m(3) (IQR, 0.46-0.71)]. Nicotine concentrations in bars and restaurants were 710 and 114 times higher, respectively, compared with hospital concentrations after adjustment for smoking ban signs, type of ventilation, and volume of the area. Support for smoke-free environments was high, except in bar/restaurant and airport workers. Airborne nicotine levels in Guatemala were similar to those found in other Latin American cities.
In Guatemala, exposure to secondhand smoke is highly prevalent. Workers in bars and restaurants are disproportionately exposed to secondhand smoke compared with other workers. There is an urgent need for complete smoke-free legislation and for educating workers about the benefits of smoke-free workplaces.
测量危地马拉工作场所的二手烟水平,并将其暴露情况与其他拉丁美洲城市进行比较。
通过使用滤器徽章对气相尼古丁进行被动采样来估计暴露情况。滤器放置在1家医院、1所学校、2所大学、1座政府大楼、机场以及10家餐馆/酒吧。总共部署了103个滤器(外加7个重复样本和10个空白样本)。通过气相色谱法测量尼古丁(微克/立方米)。报告尼古丁浓度的中位数[四分位间距(IQR)],并与其他拉丁美洲城市进行比较。在员工中开展了一项关于无烟工作场所态度的调查。
在大多数(68%)被调查场所(包括禁烟的工作场所)检测到了尼古丁。最高水平出现在酒吧[中位数,4.58微克/立方米(IQR,1.71 - 6.44)]和餐馆[中位数,0.56微克/立方米(IQR,0.46 - 0.71)]。在对禁烟标志、通风类型和区域体积进行调整后,酒吧和餐馆中的尼古丁浓度分别比医院中的浓度高710倍和114倍。除了酒吧/餐馆和机场工作人员外,对无烟环境的支持率很高。危地马拉空气中的尼古丁水平与其他拉丁美洲城市的水平相似。
在危地马拉,二手烟暴露非常普遍。与其他工人相比,酒吧和餐馆的工作人员接触二手烟的比例过高。迫切需要全面的无烟立法,并对工人进行关于无烟工作场所益处的教育。
