ioaerosol is commonly defined as aerosolized particles, with a biological origin, spread into the air by a variety of abiotic and biotic
mechanisms. The size of bioaerosol can range from several nanometers to a few hundred micrometres in aerodynamic diameter.
Examples of bioaerosols include fungal and bacterial spores/cells, fungal hyphae, pollen, viruses and amoebae, algae, lichen, archaea,
aggregates of these particles, and fragments of larger organisms including leaf litter, skin scales, animal and plant debris. Metabolites
and excreta are also included in this topic. In these last years the knowledge about indoor and occupational bioaerosol exposure and
related diseases has significantly increased. Biological particles have been linked to mucous membrane irritation, allergy, asthma,
inflammatory lung diseases, hypersensitivity pneumonitis and so on . The use of biomarkers as a tool for the determination of
bioaerosol has often been suggested. The basis of this approach is that bioaerosol components contain chemical compounds that can
be used as markers of larger and/or bioactive structures. The main objective of our research is the identification and quantitation of
dipicolinic and muramic acids, ergosterol, poliols, amino acids and proteins as markers of bacterial, fungal spores/cells and generic
bioaerosol, in both indoor and outdoor airborne particulate matter. To achieve this purpose, methods of extraction and analysis by
chromatographic techniques coupled to mass spectrometry of different classes of compounds from particulate matter of different size
(ultrafine, fine and coarse), collected in proper sampling campaigns, have been developed.
Biography
Francesca Buiarelli completed her PhD in Chemical Sciences in 1992 and, after several years of work experience, became a Researcher in the field of Analytical
Chemistry at Chemistry Department of Rome University “La Sapienza” in 1999. She has been teaching Separative Chemistry since 2002 and has published more
than 45 papers in reputed journals. Her research activity involves three main topics: 1) Characterization of polluting agents in airborne particulate matter, water
and soil. 2) Excretion study and metabolism of doping agents in sports and veterinary field. 3) Separation and characterization of natural organic compounds in
complex matrix such as food.
