Indoor air Quality in Offices and Classrooms in Public Utility Building - A Case Study

Abstract A microbiological analysis of indoor air quality in offices, lecture rooms, and hallways a public utility building has been carried out the Lubuskie Voivodship (Poland). In one storage presence fungi on partition was found place water infiltration as result technological failure building. total 17 non-residential interiors were examined. The number psychrophilic mesophilic bacteria sampled by collision method with sampler. qualitative performed present from studied interiors. 11 species have specified. Relative humidity temperature measured hygrometer. studies showed that range 0–730 CFU/m 3 , while slightly higher (0 - 896 ). high level contamination large (734 ) room, where problem biodeterioration partitions occurred. remaining microorganisms low or moderate. Microbiological tests outdoor (background) did not reveal an excessive air.
