Abstract

We observed fungal colonies on unused paper-clay bricks in a sculptural studio and had concern for mold exposure among the artists. Using two methods (Aerotech 6™ and Zeflon cassettes) we evaluated fungal concentrations inside and outside the facility prior to, during and following clay handling. Fourteen taxa of fungal colonies and spores were identified microscopically (400-1000X). The indoor/outdoor ratio prior to fabrication activities was 1.50 for viable fungi and 0.99 for total spores. The indoor ratios (pre-activity to activity) were 11.60 for viable fungi and 11.02 for total spore counts. During fabrication viable fungal concentrations by species were: Aspergillus (7-493 CFU/m3), Cladosporium (7 51 CFU/m3), Mucoraceae (14-813 CFU/m3) and Penicillium (7-813 CFU/m3) while total spore concentrations were: Cladosporium (13- 213 spores/m3), smut (40-533 spores/m3), and the combination of Penicillium/Aspergillus spores (13 - 1240 spores/m3).
