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.

Pollen allergy risk map, updated 17th of March

From the south-west to the south-east of the country, Cupressaceae-Taxaceae pollens (cypress...) will be very present in the air and will bother allergy sufferers with moderate concentrations and a high level of allergy risk. 

While waiting for the arrival of birch pollens at the end of the month, allergy sufferers will still have to be wary of alder pollens which will be responsible for a low or medium level of allergy risk. Hazel pollens flowering is ending with an allergy risk that will not exceed the low level. 

Ash, hornbeam, elm, willow and poplar pollens are also present with a low risk of allergy but which could increase if temperatures remain high. The first grass pollens are arriving from the south-west of the country but with a risk that will remain low. Parietaria pollens (urticaceae) may bother allergy sufferers on the Mediterranean area with a low to medium risk.
