Plastics - Determination of aerobic biodegradation of non-floating plastic materials in a seawater/sediment interface - Method by analysis of evolved carbon dioxide (ISO 19679:2016)
ISO 19679:2016 specifies a test method to determine the degree and rate of aerobic biodegradation of plastic materials when settled on marine sandy sediment at the interface between seawater and the seafloor, by measuring the evolved carbon dioxide.
This test method is a simulation under laboratory conditions of the habitat found in different seawater/sediment-areas in the sea, e.g. in a benthic zone where sunlight reaches the ocean floor (photic zone) that, in marine science, is called sublittoral zone
The determination of biodegradation of plastic materials buried in marine sediment is outside the scope of ISO 19679:2016.
Measurement of aerobic biodegradation can also be obtained by monitoring the oxygen consumption, as described in ISO 18830.
The conditions described in ISO 19679:2016 may not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.
Kunststoffe - Bestimmung des aeroben Bioabbaus von nicht-schwimmenden Kunststoffmaterialien in einer Meerwasser/Sediment-Schnittstelle - Prüfverfahren mittels Analyse des freigesetzten Kohlenstoffdioxids (ISO 19679:2016)
Plastiques - Détermination de la biodégradation aérobie des matières plastiques non-flottantes à l'interface eau de mer/sédiments - Méthode par analyse du dioxyde de carbone libéré (ISO 19679:2016)
L'ISO 19679:2016 spécifie une méthode d'essai permettant de déterminer le taux et le niveau de biodégradation aérobie des matériaux plastiques lorsqu'ils se trouvent sur des sédiments sableux marins à l'interface entre l'eau de mer et le fond océanique, en mesurant le dioxyde de carbone libéré.
Cette méthode d'essai est une simulation, dans les conditions de laboratoire, de l'habitat rencontré dans différentes zones d'eau de mer/de sédiments en mer, par exemple dans une zone benthique où les rayons du soleil atteignent le fond océanique (zone photique) c'est-à-dire ce qu'on appelle, en science marine, la zone sublittorale.
La détermination de la biodégradation des matériaux plastiques enfouis dans les sédiments marins est hors du domaine d'application de l'ISO 19679:2016.
Le mesurage de la biodégradation aérobie peut également être obtenu en surveillant la consommation d'oxygène, comme décrit dans l'ISO 18830.
Les conditions décrites dans l'ISO 19679:2016 ne correspondent pas nécessairement aux conditions optimales permettant d'obtenir le taux maximal de biodégradation.
Polimerni materiali - Ugotavljanje aerobne biodegradacije neplavajočih plastičnih materialov v vmesnem predelu med morsko vodo in peščenim sedimentom - Metoda z analizo sproščenega ogljikovega dioksida (ISO 19679:2016)
Standard ISO 19679:2016 določa preskusno metodo za določevanje stopnje in hitrosti aerobne biorazgradnje polimernih materialov na peščenem morskem sedimentu na vmesni točki med morsko vodo in morskim dnom na podlagi merjenja sproščanja ogljikovega dioksida.
Ta preskusna metoda je simulacija morskega habitata v različnih morskih vodah/območjih s sedimenti, npr. v bentalnem območju, kjer sončna svetloba doseže oceansko dno (fotično območje), ki se v morski znanosti imenuje sublitoralno območje, pod laboratorijskimi pogoji.
Določevanje biorazgradnje polimernih materialov, zakopanih v morskem sedimentu, ne spada na področje uporabe standarda ISO 19679:2016.
Aerobna biorazgradnja se lahko meri tudi s spremljanjem porabe kisika, kot je opisano v standardu ISO 18830.
Pogoji, ki so opisani v standardu ISO 19679:2016, niso vedno enaki idealnim pogojem, pri katerih pride do največje stopnje biorazgradljivosti.
