Soil quality - Determination of the effects of pollutants on soil flora - Leaf fatty acid composition of plants to assess soil quality (ISO 21479:2019)
This document describes a method to compare the quality of soils by determining the fatty acid composition of the leaves of plant species grown in these soils.
This method does not make it possible to determine an optimal value of the Omega-3 index and, therefore, cannot be used to determine the intrinsic quality of a soil from a specific area (regarded as homogeneous). The method can only be used to compare the quality of soils between various areas.
This method is applicable to:
— soils from contaminated sites;
— amended soils;
— soils after remediation;
? soil with waste products (e.g. slurry, manure, sludge or composts).
Alternatively, the quality of soils can be assessed by determining the Omega-3 index of Lactuca sativa seedlings grown in these soils under controlled conditions (i.e. phytotronic chamber) and by comparing these values to those obtained from control soils (see Annex B).
Bodenbeschaffenheit - Bestimmung der Wirkungen von Schadstoffen auf die Bodenflora - Fettsäurezusammensetzung in Blättern zur Beurteilung der Bodenbeschaffenheit (ISO 21479:2019)
Gegenstand dieses Dokuments ist ein Verfahren zum Vergleichen der Beschaffenheit von Böden durch Bestimmen der Fettsäurezusammensetzung in den Blättern von Pflanzen, die auf diesen Böden wachsen.
Dieses Verfahren ermöglicht keine Bestimmung des optimalen Werts des Omega 3 Index. Daher kann es nicht dazu verwendet werden, die intrinsische Qualität des Bodens auf einer bestimmten (als homogen angesehenen) Fläche zu bestimmen. Das Verfahren kann nur dazu verwendet werden, die Beschaffenheit von Böden auf verschiedenen Flächen miteinander zu vergleichen.
Das Verfahren ist anwendbar auf:
Böden von kontaminierten Standorten;
verbesserte Böden;
Böden nach Altlastensanierungen;
Böden, auf die Abfallprodukte (z. B. Flüssigmist, Gülle, Schlamm oder Kompost) aufgebracht wurden.
Alternativ kann die Beschaffenheit von Böden beurteilt werden, indem der Omega 3 Index von Lactuca sativa Keimlingen bestimmt wird, die in diesen Böden unter kontrollierten Bedingungen (d. h. in einer Wachstumskammer) gezogen werden, und diese Werte mit den bei Kontrollböden erhaltenen Werten verglichen werden (siehe Anhang B).
Qualité du sol - Détermination des effets des polluants sur la flore du sol - Composition en acides gras foliaires des plantes utilisées pour évaluer la qualité du sol (ISO 21479:2019)
Le présent document décrit une méthode visant à comparer la qualité des sols en déterminant la composition en acides gras des feuilles d'espèces végétales poussant sur ces sols.
Cette méthode ne permet pas de déterminer une valeur optimale de l'indice Oméga-3 et ne peut donc pas être utilisée pour déterminer la qualité intrinsèque d'un sol d'une zone spécifique (considérée homogène). La méthode peut être utilisée uniquement pour comparer la qualité des sols entre plusieurs zones.
Cette méthode est applicable à:
— des sols provenant de sites contaminés;
— des sols amendés;
— des sols après remédiation;
— des sols contenant des produits résiduaires (par exemple lisier, fumier, boues ou composts).
La qualité des sols peut aussi être évaluée en déterminant l'indice Oméga-3 de plantules de Lactuca sativa poussant dans ces sols dans des conditions contrôlées (c'est-à-dire, enceinte phytotronique) et en comparant ces valeurs avec celles obtenues à partir de sols témoins (voir l'Annexe B).

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
