Abstract: An investigation of the quantity of dustborne microbes in 5 different locations of El-Beida City, Libya was carried out to assess the level of dustborne pathogens in different locations and studied the monthly and seasonal distribution for dustborne fungi. A total of 719 mould colony were collected. Mould colonies were assigned to 10 genera and 13 species. The highest abundance was attributed to P. chrysosgenium with a percentage of 29.1% of the total colony count followed by P. digitatum 20.2%, R. nigricans 16.4%, F. solani 10.7%, T. roseum, 9.9%, A. alternata 3.8% and A. niger 3.6%. P. chrysosgenium showed one peak in June while A. alternata and P. digitatum peaked in June. R. nigicans peaked in April and June and F. solani in April. However, T. roseum showed almost the same abundance from January to May and then in August to November. With respect to seasons it was found that in Summer, A. alternata, P. digitatum and R. nigicans, in Autumn P. chrysogenum and T. roseum. In Spring, A. niger and F. solani. Winter had the least number of total colony. P. chrysogenum were the most prevalent fungal genera. In addition most of fungi isolated were important aeroallergens and phytopathogen.
