Air Quality Assessment
In 1973/1974, the importance given to air-quality issues in Upper Normandy led to the set-up of Air Normand, among the first air-pollution monitoring networks to be created in France. Today, it is a part of the national monitoring network, made up of 36 associations approved by the French Ministry for the Environment. All air-quality monitoring networks are non-profit associations under the French Law of 1901. They comprise four groups that are involved in atmospheric pollution issues and that represent local authorities, the State, industry, and consumer and environmental associations, as well as health professionals.

Air Normand has two missions: to monitor air pollution by combining fixed stations with mobile means and to inform population, indeed, all the results are made public and are used by a wide range of partners. Air Normand takes part in an operational alert process put in place by the Prefects to trigger the public health protective measures and reduce pollutant emissions.

In addition to traditional measurements, digital modelling tools are being increasingly used for monitoring purposes in order to prepare cartographies and prepare forecasts or assess the extent to which the population is exposed to different pollutants. These tools, designed to inform the general public, build in different data sources (emissions registry, meteorological data, and topography).

At least, Air Normand took on the problem of odours 20 years ago: pollution and smells are often mentioned together. However, they can be differentiated both with regard to their effects and the techniques that make it possible to measure them. Although sensors are able to analyse air pollutants, they are not suited to measuring odour pollution. In 1991, Air Normand started an odour tracking campaign. Groups of people, living near industrial sites, have since become together the "Nez Normands" (Normandy Noses). These volunteers, after having been introduced to an odour referencing method, have become nasal experts, and are able to define and measure odour pollution that is part and parcel of everyday life. The results are compared with the emission profiles of partner companies. This exemplary method has demonstrated its effectiveness through the implementation of steps to reduce odours within the industrial processes themselves.
