İÇ VE DIŞ ORTAMLARDA BİYOAEROSOL SEVİYELERİ VE KAYNAKLARININ TESPİTİ

Abstract

People spend about 90% of their life in indoor environments. Therefore air of the indoor environments has a great effect on the public health.Air pollution is one of the leading environmental factors that affect human health negatively and it has been reported that indoor air is more effective than outdoor environments on human health.Indoor air pollution causes upper and lower respiratory tract diseases and pneumonia, especially in infants and children whose defense system is not yet developed. So, for evaluation of indoor air quality and determination of risks and hazards,thisstudy was undertaken and total of 119 voluntary pregnant women living in different districts of Ankara were selected and Bioaerosol sampling was performed in bed room, sitting room and outdoor environment of every flat.It was observed that, concentration of bacteria and fungi were measured during spring-summer higher tan autumn-winter. Also the highest level of bacteria and fungi were measured in sitting rooms. The dominant bacteria and fungi in the air of examined dwellings are Staphilicoccus, Corynebacteria, Streptococcus, Neisseria, Basillus, gr(-) Basillus and Penicillium, Sporothrix, Aspergillus, Rhizopus, Alternaria, Stachybotrys and whitecolon‎y. In addition, the measured bacterial level in the indoor environment is 5.75 times and level of the fungi is 3 times more than outdoor environment. According to the obtained results, building characteristics such as; age of building, materials used, type of paint and socio-demographic characteristics of families, lifestyle habits, physical characteristics of the environment and amount of salary, severely affect the level of bacteria and fungi in the indoor environments. During two years, respiratory allergies, eczema, rash itching were observed in infants living in homes with high levels of bacteria and fungi inside. After identifying the sources of bacteria and fungi in indoor environments, solutions have been presented which show how to reduce or eliminate bacteria and fungi that cause health problems for the general population.
