Nature of airborne particulates at tropic exposure sites. Final report, November 1982-September 1984
Technical Report
·
OSTI ID:6801604
Airborne particulates were collected at five exposure sites in Panama using cascade impactor air samplers. Scanning electron microscopy, energy dispersive x-ray analysis, and culture identification techniques were used to analyze the particulates. Analysis revealed that the particulates consist of silicates, chlorides, and sulfur-rich and phosphorus-rich particles. Atmospheric particle levels were higher in the dry season than in the rainy season, and the predominant fungal species varied at each exposure site. The open direct exposure of culture plates served as a simple, appropriate method for monitoring atmospheric fungal spores.
