Concentration op viable microorganisms in Indoor settled dust and its relation with meteorological parameters in Baghdad city

Abstract

Samples of settled dust were collected from schools, factories and hospitals during twelve successive months for measuring the concentrations of viable microorganisms. High concentrations of aerobic, anaerobic bacteria and fungi were present in schools, mean number 216.06×10 3 , 153.8×10 3 and 122.56×10 3 /g ofdust respectively followed by factories i.e. 186.55×10 3 , 200.23×10 3 and 97.76×10 3 /g and then hospitals, i.e. 141.02×10 5 , 74.*44×10 3 and 85.24x10 3 /g. The concentration of microorganisms was directly proportional to the 145 Copyright© 1983 by Marcel Dekker, Inc.

Monitoring Indoor Airborne Fungi and Bacteria in the Different Areas of Trakya University Hospital, Edirne, Turkey

“…Corden and Millington [33] observed that the dayto-day spore levels show a positive correlation between Alternaria spore concentrations and maximum temperature. Also according to Jazrawi and Al-Shahwani [34], the concentration of micro-organisms was directly proportional to the atmospheric temperature. In addition, the total level of airborne bacteria is a risk factor for asthma [35], and inhalation of microbial aerosols may cause allergic responses.…”
