How ambient environment effects the migration of particulate matter?

The paper reviews the effect of environmental parameters on the migration of particulate matter. Themethodology involves simultaneous monitoring of particulate matter using dust monitor at indoor and outdoor locations along with the ambient environmental conditions. The study is of great significance as Particulate Matter (PM) has been reviewed in terms of particle count, which is more significant as compared to particle mass. In this paper, the variation of Indoor (PM) /Outdoor (PM) calculated on the basis of count are studied as a function of ambient wind speed, temperature and humidity. Further detailed characterization of the PM on the basis of count is done to signify the importance of fine particles specifically PM1 in comparison to PM10. This study can help in designing ventilation strategy for naturally-ventilated buildings. Similar studies can help in selecting fresh air intake points for mechanically ventilated buildings in order to minimize the migration of air pollutants into the indoor environment.
