Soil quality - Laboratory incubation systems for measuring the mineralization of organic chemicals in soil under aerobic conditions (ISO 14239:2017)

ISO 14239:2017 specifies six suitable incubation systems for measuring the rates and extent of mineralization of organic compounds in soil by measurement of carbon dioxide (CO2) evolution. All incubation systems are applicable to soluble or insoluble compounds but choice of system depends on the overall purposes of the study.
ISO 14239:2017 does not apply to the use of such systems for material balance studies, which are often test-substance specific.

Bodenbeschaffenheit - Laboratoriumsinkubationssysteme zur Bestimmung der Mineralisierung von organischen Chemikalien im Boden unter aeroben Bedingungen (ISO 14239:2017)

Dieses Dokument legt sechs geeignete Inkubationssysteme für die Bestimmung der Rate und des Umfangs der Mineralisierung organischer Verbindungen im Boden durch Messung der Kohlenstoffdioxidentwicklung (CO2) fest. Alle Inkubationssysteme sind für lösliche oder unlösliche Verbindungen verwendbar, jedoch hängt die Wahl des Systems vom Zweck der Untersuchung ab.
Dieses Dokument gilt nicht für die Anwendung solcher Systeme für Materialbilanzuntersuchungen, die oft prüfsubstanzspezifisch sind.

Qualité du sol - Systèmes d'incubation de laboratoire destinés à la mesure de la minéralisation de produits chimiques organiques dans le sol en conditions aérobies (ISO 14239:2017)

ISO 14239:2017 définit six systèmes d'incubation appropriés permettant de mesurer les vitesses et l'étendue de la minéralisation de composés organiques dans le sol par mesurage du dégagement de dioxyde de carbone (CO2). Tous les systèmes d'incubation peuvent être utilisés avec des composés solubles ou insolubles, mais le choix du système dépend des objectifs globaux de l'étude.
ISO 14239:2017 ne s'applique pas à l'utilisation desdits systèmes pour les bilans de masse, qui sont souvent spécifiques de la substance d'essai.
