Indoor air measurements for particle pollution

Many research papers deal with the influence of indoor air particulate pollution related to human health. People usually spend most of the time indoors, so the air quality is very important. Bucharest is one of the most polluted city in Europe concerning particle matter. Almost every day the concentration outdoors is higher than the maximum limit, that's why fast measures to limit particle pollution should be found and implemented accordingly. The originality of the present paper is to show the influence of particles' concentration as a function of: activity type, season (autumn, winter), and also the indoor air cleaning device influence over the concentration of particles. The final purpose of the study aims to present measures to reduce particle pollution, for cities having a high concentration levels. Using particle counters of new generation, laser aerosol Grimm 11E type, accurate results will be provided for PM2.5, PM1 and PM10. Comparison between different locations studied and different indoor activities are interesting to be presented in the present research.
