Introduction
Biological particles (pollen and fungal spores) are present in the air, causing health impacts at various
levels. In Europe, nearly 18 % to 20 % of people suffer from pollinosis due to pollen and/or fungal
spores. Pollen grains and fungal spores are considered in some Member States as an air pollutant as
well as particles suspended in the air (PM , ). In Europe, European Aerobiology Society (EAS) in
10 2,5
coordination with International Association for Aerobiology (IAA) manage problems of sampling,
analysis, quality control, development and information.
For the sampling and analysis of biological particles different methodology and operating procedures
are used.
Sampling equipment is diversified (see Annex A). Analysis is based on optical light microscopy for
identification and counting pollen grains and fungal spores.
Elements and reagents used during sampling and analysis have very specific properties and require to
be handled carefully.
Given the close relationship between aerobiology and other sciences, one of the main aims is that
information on airborne biological-particle counts should be of use in a wide range of disciplines and
fields of application, including aerobiology, biodiversity, agriculture, forestry, phytopathology,
meteorology, climatology, forensic science, bioterrorism, and health (sensitization and allergy).
