Air biomonitoring - Passive biomonitoring of the air quality using autochthonous lichens : from collecting to sample prepar

Le présent document décrit une méthode pour l'échantillonnage et la préparation d'échantillons de lichens in situ pour la bioaccumulation de substances caractérisant une pollution atmosphérique. Il définit les actions à mener depuis le prélèvement in situ de lichens sur troncs d'arbres jusqu'au conditionnement final et au transport des échantillons en vue de l'analyse des contaminants recherchés. Il s'applique aussi bien à la mise en évidence (localisation) d'une source locale de pollution et/ou de sa zone d'influence, qu'à la cartographie des niveaux de pollution de fond à l'échelle nationale, voire internationale.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
