Airborne fungi were monitored at five sample sites with the Burkard po
rtable, the RCS Plus, and the SAS Super 90 air samplers; the Andersen
2-stage impactor was used for comparison. All samplers were calibrated
before being used simultaneously to collect 100-liter samples at each
site. The Andersen and Burkard samplers retrieved equivalent volumes
of airborne fungi; the SAS Super 90 and RCS Plus measurements did not
differ from each other hut were significantly lower than those obtaine
d with the Andersen or Burkard samplers. Total fungal counts correlate
d linearly with Cladosporium and Penicillium counts. Alternaria specie
s, although present at all sites, did not correlate with total count o
r with amounts of any other fungal genera. Sampler and location signif
icantly influenced fungal counts, but no interactions between samplers
and locations were found.
