在美国，二手烟暴露仍然是一个主要的公共卫生问题。住房已成为SHS暴露的主要来源，多单元住房的居民风险更高。虽然这种不同的风险是有据可查的，但很少有人知道SHS暴露是否因楼层高度而异。本研究的目的是检验SHS是否在多单元住宅的较高楼层累积。使用经过验证的被动尼古丁采样监测仪，我们对纽约市21栋高层建筑（bbb15层）的多个楼层的空气尼古丁浓度进行了采样。在建筑物内，测量数据收集于三个地点：非吸烟的独立公寓、走廊和楼梯间。收集了两次冬季和两次夏季波浪的测量数据，以解释潜在的季节性影响。我们分析了可检测尼古丁的过滤器的百分比和尼古丁的定量浓度（µg/m3）。较高的地板水平与空气中尼古丁含量呈正相关，不同地点和季节有一定差异。冬季，公寓（楼层≤7:0.022µg/m3, 8-14层：0.026µg/m3，≥15层：0.029µg/m3, p = 0.011）和楼梯间（楼层≤7:0.18µg/m3, 8-14层：0.19µg/m3，≥15层：0.59µg/m3, p = 0.006）的趋势具有统计学意义。这些发现可以为干预措施提供信息，以减轻多单元住房居民的SHS暴露。
Secondhand smoke (SHS) exposure remains a major public health concern in the United States. Homes have become the primary source of SHS exposure, with elevated risks for residents of multiunit housing. Though this differential risk is well-documented, little is known about whether SHS exposure varies by floor height. The aim of this study was to examine whether SHS accumulates in higher floors of multiunit housing. Using validated passive nicotine sampling monitors, we sampled air nicotine concentrations on multiple floors of 21 high-rise (>15 floors) buildings in New York City. Within the buildings, measurements were collected in three locations: non-smoking individual apartments, hallways and stairwells. Measurements were collected in two winter and two summer waves to account for potential seasonality effects. We analyzed the percent of filters with detectable nicotine and quantified nicotine concentration (µg/m3). Higher floor levels were positively associated with both airborne nicotine measures, with some variation by location and season observed. In winter, the trends were statistically significant in apartments (floors ≤7: 0.022 µg/m3; floors 8–14: 0.026 µg/m3; floors ≥15: 0.029 µg/m3; p = 0.011) and stairwells (floors ≤7: 0.18 µg/m3; floors 8–14: 0.19 µg/m3; floors ≥15: 0.59 µg/m3; p = 0.006). These findings can inform interventions to mitigate the SHS exposure of residents in multiunit housing.
