What is it about?
Fine and ultra-fine aerosols were studied in an indoor environment. elemental analysis and phase identification showed that anthropocentric sources: mainly traffic, energy generation and industrial emissions are the major constituents of particles with cutoff diameters of 0.5 and 0.25 micrometers, while natural sources such as dust storms and crustal materials are the main constituents of larger particles. infiltration of outdoor pollutants enters the structures through air conditioning, doors and windows.

Why is it important?
Particulate matter pollution particularly fine and ultra-fine sizes have sever health consequences. WHO reported that about 7 million deaths worldwide in one year were attributed to both indoors and outdoors air pollution. Identifying sources of pollutants can help in suggesting remediation procedures. Indoors pollution is particularly important because it consists of mainly fine and ultra-fine sizes that can penetrate deep into the lung and get into eh blood stream. It is also an important topic because we spend more than 85% of our time indoors exposed to these pollutants.
Perspectives
This work is part of larger project that we study both indoors and outdoors. We are currently performing source apportionment of outdoor PM2.5 through a three-year sampling campaign at an urban background site. The project is part of a regional project in collaboration with the IAEA. We are also working on two major projects: Pm pollution in dental simulation laboratories at a dental school and a major study of air quality inside galleries of a Museum,
