摘要

Aerobiological studies are widely used to determine the fungal spectrum in the air. These studies have revealed that Aspergillus/Penicillium spores are the most abundant spores in both outdoor and indoor environments. In this study, we have presented the variations in the concentration of these spores in an indoor environment (a potato store). Aerobiological sampling was conducted during five storage period (from 2002 to 2008 year) using a Hirst-type spore trap. The maximum spore concentrations were counted during the second fortnight of January and in the months of February and March, with values higher than 6,000 spores/m(3) per day. A correlation analysis between the Aspergillus/Penicillium spores and the main environmental parameters was performed; significant coefficients were obtained for spores present in the store previous days and mean temperature of the same day and previous days (P%26lt;0.001). Moreover, a regression model was established and predicted 53% variability of the data included in the analysis. The best obtained model took into account the Aspergillus/Penicillium spore type levels of 1 previous day and the mean temperature in the preceding 2 days.
