Moyenne des valeurs observées sur la période. Pour les mesures inférieures à la limite de quantification, en accord avec les textes réglementaires, la valeur prise en compte pour le calcul est égale à LQ/2

Les valeurs en italique indiquent le seuil de quantification lorsque aucune analyse n'a été quantifiée sur la période
