Abstract:
PM pollution is high in developing countries, where the quality of air is unhealthy due to large emission of PM2.5 into the atmosphere associated with a large manufacturing industry. Because of the increased morbidity and mortality due to respiratory problems created by long term exposure to PM, their emission is highly regulated. However, people should protect themselves during hazy days using mask filters, but these measures focusses on outdoor individual protection. For indoor protection, there is air conditioning to filter and ventilate the air, but most of the time the filters are not properly maintained or correctly sized for a given space. The amount of PM2.5 indoor is influenced by the concentration of PM2.5 outdoors, and the accumulation of PM2.5 depends on the atmospheric conditions, the condition of the building (i.e. infiltration through the cracks and gaps in building envelope) and the ventilation system (i.e. natural and mechanical). People are not aware that indoor pollution could be higher that the outdoor, however there is relatively little information on ambient concentration and composition of PM2.5 for indoors than for PM10. Because of their small size, PM2.5 are not filtered in the nose or throat; they can settle in the lungs and cause health problems. There are many studies that demonstrate PM behaviour and their harmful impact to health. The aim of this paper is to analysis the level of pollution with PM2.5 in an office. The office is situated in Bucharest, Romania, in a green area and far from the main traffic. Our initial measurements showed that only 4% of the PM2.5 level exceeded the threshold for the daily values of 25 µg/m3.
