Le Réseau National de Surveillance Aérobiologique (R.N.S.A.) is the French aerobiology network in charge of the analysis of the content of the air in biological particles, and to give some information about their health impact. This activity began in 1985 to the Pasteur Institute. It is a private association "RNSA" since 1996.
RNSA collect pollen and moulds in the air, and clinical data, from 70 towns in France. In each great town, RNSA has a pollen trap (Burkard or Lanzoni), an analyst and a clinician. RNSA has nearly 65 pollen traps located on a central urban position over the roof of building, to be representative of the trend air quality.
