Abstract : Sampling of ambient air using a glass cyclone system for fluorescence background determination is described. Weekly samples were taken at the University College Galway's atmospheric research field station at Mace Head, on the west coast of Ireland. The bioaerosol sampling system and procedures used have previously been discussed in the 1st Interim Report. Use is made of a fluorescence protocol developed in the ERDEC Laboratories. Representative fluorescence excitation/emission spectra are presented for both background and polluted conditions. In addition, mass distributions of both, background and polluted air episodes at the Mace Head site are also presented.
