This report presents the results of an expert consultation whose objectives were to review and assess the current scientific evidence on questions related to protection measures that individuals can take (or so-called personal interventions) to reduce their exposure to air-pollution. Such measures include wearing respirators, using indoor portable air filters (cleaners) or avoiding certain places and limiting activities or exercising in an environment with high levels of air-pollution. It was agreed, however, that these measures are the least desirable choice in the hierarchy of interventions – the most preferred being public policies aiming at reducing emissions. The report also discusses the communication challenges associated to information related to air-pollution and health impacts, such as air-pollution sources, air-quality Index (AQI), and the role of medical societies
