<p>The aim of this study was twofold: 1) to compare two different bio aerosol
sampling techniques, polycarbonate filters, and Coriolis®µ and 2) characterise
bioaerosols by the analysis of PLFA biomarkers in order to
identify the microbial communities present in contrasting outdoor environments (a WWTP, compost facility, three different
farms, 2 parks and an urban area). Sample
collection efficiency was 34% greater when collecting air samples with
polycarbonate filters than with Coriolis in recreational parks where there is a
low microbial activity. Areas with higher diversity index in the microbial
communities corresponded to the ones with a higher amount of PLFAs such as the
WWTP and the composting facility (1.986 and 1.624 respectively). Actinomycetes
were only found in industrial and urban areas. No site specific PLFA was found
and only the PLFA profile from the composting facility was different from the
rest of the sites. This chemical approach therefore might not be enough to
differentiate different bioaerosol profiles from outdoor environments.</p>
