This patented technique is based on a flora
study, according to the nitrogen oxides sensitive species. It was
finalized in association with the Paris City Council and allows
to differentiate the atmospheric average content in nitrogen oxides.
Extract of a map of modeling Li-NOx®: industrial parks
in urban zones.
The sensitive sectors appear in red.
3 lichens highly resistant species to nitrogen
3 resistant species
4 tolerant species
3 lightly resistant species
NOx non significatifs
3 absent species in front of nitrogen oxides
Used experimentally on the whole important
metropolis, it enters an active phase at the industrial survey.
A biomonitoring from the initial data is possible in identical conditions
to those of the IGQA®.
