[Impact of the new smoke-free legislation (law 42/2010) on levels of second-hand smoke in hospitality venues].
OBJECTIVE
To evaluate pollution by second-hand smoke in a sample of hospitality venues before and after the implementation of smoke-free legislation.


METHODS
A cross sectional, before-after study was conducted in 2008 and 2011 after the total ban. A SidePack Aerosol monitor was used both inside and outside the hospitality venues to measure fine breathable particles (PM2.5). A total of 43 places with pre- and post-legislation measurements were included.


RESULTS
The median indoor pollution in hospitality venues was 204.2μg/m(3) in 2008 and 18.82μg/m(3) in 2011; the average outdoor PM2.5 concentration was 47.04μg/m(3) in 2008 and 18.82μg/m(3) in 2011. Pollution was higher in bars and cafeterias, followed by pubs and discos. Before the law was implemented, pollution was 4.34 times higher indoors than outdoors; in 2011 the average indoor PM2.5 concentration decreased by 90.88%.


CONCLUSIONS
Only a complete ban is able to protect workers and customers against the health risks of second-hand smoke exposure.
