Assessment of Sick Building Syndrome Symptoms and its Risk Factors in Employees in Some Buildings of University

Sick building Syndrome is a Collection of neurological, irritancy, respiratory, dermatology & sensory symptoms that we can not relate them to the diagnosis of other diseases. With recognized people having sick building syndrome, we can make better environment for them at work & try to prevent the sickness.The aim of this study was assessment of symptoms of sick building syndrome & determination of indoor air pollutants in some buildings of university. This study was a cross – sectional assessment, it accomplished with special methods for the measurement of indoor air pollutants & questionnaires. There was a maximum of 4 weeks time interval between the measurement and filling the questionnaires. Data were analyzed using SPSS 11.5, chi –square, ANOVA using p< 0.05. A total of 23.3% of personnel’s had sick building syndrome,21.9% of them had only neurological, 10.3% irritancy, 5.2% respiratory, 6.8% dermatologic & 4% had sensory symptoms. Mean of the indoor air pollutants for CO2, Ozone, CO & NOx were 526.93, 0, 4.92,0 PPM respectively. Mean of formaldehyde was 0.15 μg/m3 respiratory particles 3.56 μg/m3, total particles 5.793 μg/m3, wet temperatures 14.28 ◦C & 22.27 ◦C for dry temperature. Humidity was 41.36%, air velocity 0.16 m/s, noise 58.38 dBA, light or luminosity 421.37 lux. Bacteria and fungi were 1.73 & 0 CFU/m3 respectively. In building C, neurological symptoms with increasing CO were shown. The results of this study are similar to those from other studies & may be even more significant. It can be concluded that by making a better working environment and ventilatin of buildings, sick building syndrome could be avoided to some degree.
