Abstract : Sampling of ambient air using a glass cyclone system for fluorescence background determination is described. Twice weekly samples were taken at the University College Galway's atmospheric research field station at Mace Head on the west coast of Ireland. The work is undertaken in collaboration with the Aerobiological Laboratory at ERDEC, MD. The bioaerosol sampling system and procedures are described in this first Interim Report. Use is made of a fluorescence protocol developed in the ERDEC Laboratories. Preliminary analyses have also been carried out of the natural background aerosol particle size distribution, measures using a TSI aerodynamic particle sizer at the same time as the bioaerosol sampling. Representative measurements of background aerosol size, surface and volume distributions for clean marine air and for polluted air at the Mace Head site are also presented.
