Abstract:

from march/1993 to march/1995, airborne fungi were isolated from the "vale do rio moji" (highly affected by the air pollution caused by fertilizer industries, steel works, cement factories and chemical products industries, among others) and from the "vale do rio pil?es" (less affected by the air pollution), both in the municipality of cubat?o, s?o paulo state, brazil, by exposing petri dishes with potato dextrose agar medium, placed one meter from the ground, during 5 min. after 5 days of incubation at 20oc, the colonies of the fungi were purified and identified, resulting in the identification of 39 taxa, three unidentified strains of fusarium and non-sporulating cultures. a total of 28 taxa, one unidentified strain of fusarium and non-sporulating fungi (71 records) were isolated in the "vale do rio moji" and 29 taxa, two unidentified strains of fusarium and non-sporulating fungi (72 records) in the "vale do rio pil?es. the airborne mycota of the higher polluted site presented 17 common, 12 rare and only one constant fungal species. in the other site, the airborne mycota was composed by 19 common, 10 rare and two constant fungal species. among the obtained fungi, at least 12 taxa were reported as opportunistic fungi, 26 have been mentioned related to plant diseases and eight have been associated to allergy problems. the similarity index of s?rensen between the mycotas, corresponding to 58%, may be considered low, and is probably justified by the air pollution, that mainly distinguish the two studied areas.
