Indoor Air Quality In Office Buildings Research Articles

Indoor air quality (IAQ) is a growing concern, as people spend about 80–90 percent of their time indoors.It is known that IAQ in office buildings influences people’s health. Employment agencies are one of the most important institutions,where more than 1000 people visit and hold interviews everyday. Measurements were made in order to assess the IAQ that staff and visitors to the building are exposed to,and the findings were compared to WHO and ARSHAE standards.Two questionnaires were applied to the staff to have an insight into their exposure and determine its effects on health.The mean PM10 was found to be 67.73 μg/mᶾ; PM2.5 was 35.95 μg/mᶾ and sound was 67 dBA, which may pose risks for health. The first questionnaire was to measure the exposure of indoor air pollutants to individuals, who reported that ventilation is frequently inadequate (42%) and the office environment is always noisy (57%). In the second questionnaire, the participants complained of dry and sore throat (42%), frequent tearing and redness in eyes (60%). The building is an old one with a lack of ventilation and air conditioning,and an open office system is used without insulation system,which are all considered to be responsible for the obtained results.
