A comparative study on the quality of air in offices and homes

The main purpose of this study was to collect data on some of the factors that contribute to indoor air quality and to discomfort, in order to take the proper actions that can reduce the level of air pollution within houses and offices. To ascertain the contamination degree total bacterial counts, total fungal counts, suspended particulate matter, air temperature, and relative humidity have been determined. Additionally, mathematical statistical models have been elaborated for the total bacterial count, respirable particulate matter and humidity. A total number of 40 indoor air samples were collected from office and houses. The results shows that approximately 45% of the air samples from homes, and 45% of the air samples from offices had levels of total viable count higher than the recommended by "European Concerted Action-Indoor Air Quality and Its Impact on Man- Report No 12." For yeast and moulds it was observed that 40% of the air samples within homes, and 10% of the air samples within offices had levels of total viable count higher than the recommended. This highlights the need for frequent cleaning of offices and homes as well as the ventilation improvement for providing a healthy environment.
