AIRBORNE BASIDIOSPORES OF BOLETES AND THEIR POTENTIAL TO INFILTRATE A RESIDENCE IN CENTRAL CONNECTICUT

摘要

Bolete basidiospores at all locations showed diurnal patterns with night-time peaks. Bolete basidiospore concentrations inside a residence showed strong correlations with those on the outdoor deck. Dew and wind velocity correlated with both large and small basidiospores at all locations positively and negatively, respectively.RH was correlated with basidiospore concentrations outdoors, but not the small basidiospores on the deck. Rain was not correlated with bolete basidiospores. Airborne small basidiospores near the ground were correlated with the ones on the deck, but not so for large basidiospores. Spatio-temporal distributions of large basidiospores varied within a 5-m range. Human activity had a significant effect on large bolete basidiospores in the living room, but not on small ones. A significant number of bolete basidiospores entered the residence, and the concentration of small bolse basidiospores indoors reached 33301 spores/m3. However, overall the basidiospore concentration in the residence was 21% of outdoor.
