The study of the spatial distribution of atmospheric PM and of its components is essential for a reliable identification of emission sources, the evaluation of particle dispersion over the territory and the assessment of personal exposure. However, the very high cost of a network based on traditional PM samplers generally prevents the achievement of these goals. A low-cost, self-powered and automatic device for PM sampling on membrane filters has been recently become available.

Preliminary results concerning the VIEPI (Integrated Evaluation of Indoor Particulate Exposure) project are described. VIEPI project aimed at evaluating indoor air quality and exposure to particulate matter (PM) of humans within workplaces. Infiltration factors of PM in indoor environments of different sizes with different air ventilation regimes as well as their dependence on outdoor and indoor micrometeorology characteristics are some of the goals of the project. For these purposes, several indoor environments located on different sites of the Rome area were considered for the analysis.
