About a third of the world's population is exposed to secondhand smoke (SHS), despite reductions in smoking prevalence in many countries. Accurate, cost-effective measures of exposure are needed in investigations of the health risks associated with SHS, and in studies of interventions to extend smoke-free environments. There have been important ...
