Changes in exposure of adult non-smokers to secondhand smoke after implementation of smoke-free legislation in Scotland: national cross sectional survey. [BMJ. 2007]

There is anecdotal evidence that the interiors of accordions played regularly in smoke filled environments are dirtied as a result of the trapping of contaminant particles circulating in the air as it filters through the instrument. We conducted a telephone survey of all workers involved in the cleaning, repair, maintenance, and renovation of accordions in the Republic of Ireland. We managed successfully to contact six out of seven such workers.
