Second-hand smoke in hospitals in Catalonia (2009): a cross-sectional study measuring PM2.5 and vapor-phase nicotine.
Environ Res. 2010 Nov; 110(8):750-5.ER

Abstract

OBJECTIVES

To describe second-hand smoke in the hospitals of the Catalan Network for Smoke-free Hospitals using Particulate Matter (PM(2.5)) and to assess the association between second-hand smoke exposure in main entrances (outdoors) and halls and between PM(2.5) and airborne nicotine concentrations.

METHODS

Cross-sectional study carried out in 2009 in the 53 hospitals affiliated with the network. We measured PM(2.5) (μg/m(3)) in all hospitals and measured airborne nicotine concentrations (μg/m(3)) in a subsample of 11 hospitals. For each assessment, we measured nine locations within the hospitals, computing medians, means, geometric means, interquartile ranges (IQRs), and 95% confidence intervals (CI) of the means and the geometric means. Further, we used Spearman's linear correlation coefficient r(sp)) to explore the association between PM(2.5) concentrations in halls and main entrances and between PM(2.5) and nicotine concentrations.

RESULTS

The overall median of the 429 PM(2.5) measurements was 12.48 μg/m(3) (IQR: 8.84-19.76 μg/m(3)). The most exposed locations were outdoor smoking points (16.64 μg/m(3)), cafeterias (14.82 μg/m(3)), and main entrances (14.04 μg/m(3)); dressing rooms were the least exposed (6.76 μg/m(3)). PM(2.5) concentrations in halls were positively correlated with those in main entrances (r(sp)=0.591, 95% CI: 0.377-0.745), as were PM(2.5) values and nicotine concentrations (r(sp)=0.644, 95% CI: 0.357-0.820).

CONCLUSIONS

Second-hand smoke levels in hospitals were low in most locations, with the highest levels observed in outdoor locations where smoking is allowed (smoking points and entrances). Smoking in main entrances was associated with increased second-hand smoke levels in halls. Use of PM(2.5) to evaluate second-hand smoke is feasible and shows a good correlation with airborne nicotine values.
