INTRODUCTION The home can represent a significant source of secondhand smoke (SHS), especially for individuals who live in close proximity to one another in multiunit housing (MUH). The objective of this study was to quantify real-time SHS transfer between smoke-permitted and smoke-free living units within the same MUH structure. METHODS Air monitors were used to assess PM₂.₅, an environmental marker for SHS, in 14 smoke-free living units and 16 smoke-permitted units within 11 MUH buildings in the Buffalo, New York, area between July 2008 and August 2009. Air monitors were operated concurrently in both smoke-permitted and smoke-free units within each building. When feasible, additional monitors were stationed in shared hallways and on outdoor patios. Participants completed logs to document activities that could affect air quality. RESULTS Evidence of SHS transfer from smoke-permitted units was detected in 2 of the 14 smoke-free units and 6 of the 8 hallways. Real-time PM₂.₅ plots and participant logs suggest that SHS transfer is a function of many determinants, including ventilation and proximity between units. Following stratification by time of day, median PM₂.₅ levels were greatest between 4:00 PM and 11:59 PM but varied by location: 10.2 μg/m³ in smoke-free units, 18.9 μg/m³ in hallways, and 29.4 μg/m³ in smoke-permitted units. CONCLUSIONS This study documents SHS incursions from smoke-permitted units into smoke-free units and adjacent hallways within the same building. Since many factors appear to impact the amount of SHS transfer between these areas, the implementation of a smoke-free building policy represents the most effective way to ensure that residents of MUH units are not exposed to SHS.

The objective of our research was to assess resident exposure to secondhand smoke, support for no-smoking policies, and the health impacts of no-smoking policies in multiunit housing. METHODS Surveys of ...

Tobacco-smoke exposure in children who live in multiunit housing.

OBJECTIVE There is no safe level of secondhand tobacco-smoke exposure, and no previous studies have explored multiunit housing as a potential contributor to secondhand tobacco-smoke exposure in children. We hypothesized that children who live in apartments have higher cotinine levels than those who live in detached homes, when controlling for demographics. METHODS We analyzed data from the 20...

Secondhand smoke transfer and reductions by air sealing and ventilation in multiunit buildings: PFT and nicotine verification.

UNLABELLED Surveys suggest that transfer of secondhand smoke (SHS) between units in multiunit residential buildings is common, but measured data are rare. This study was undertaken to quantify bulk air transfer between units and document transfer of SHS species before and after treatments that sealed boundaries between units and provided a minimum amount of continuous exhaust ventilation of eac...

Evaluating the implementation process of a citywide smoke-free multiunit housing ordinance: insights from community stakeholders.

We evaluated the implementation process of Richmond, California's citywide smoke-free multiunit housing ordinance. We conducted semistructured focus groups with multiunit housing tenants, owners, and managers. Residents understood the harms of secondhand smoke but lacked accurate information about the ordinance and questioned its enforceability. They shared concerns that the city lacked cessati...

Tobacco use policy in military housing.

Secondhand smoke and thirdhand smoke (e.g., smoke residues found on walls and floors) are known to pose health hazards. Some landlords and cities have therefore established smoke-free policies for multiunit housing. The military is in effect the largest landlord in the United States, with approximately 630,000 units of housing. We reviewed the service-level tobacco control policies of the Army,...
