Water quality - Preparation and treatment of poorly water-soluble organic compounds for the subsequent evaluation of their biodegradability in an aqueous medium (ISO 10634: 2018)
This document specifies techniques for preparing poorly water-soluble organic compounds (i.e. liquid and solid compounds) with a solubility in water of less than approximately 100 mg/l and introducing them into test vessels for a subsequent biodegradability test in an aqueous medium using standard methods.
The subsequent tests on biodegradability are primarily methods using the analysis of the released carbon dioxide described in ISO 9439 and the determination of the oxygen described in ISO 9408 and following the usual precautions for ISO 10707. Thus, one can notice that the methods measuring the removal of dissolved organic carbon (DOC) are not appropriate.
This document does not specify the biodegradation test methods. It is restricted to describing techniques for introducing the test compounds into the test medium and to keeping them in a dispersed state[4]. These techniques are implemented while observing the experimental conditions described in the standardized methods for evaluating biodegradability. ISO 9439, based on CO2 evolution, is not suitable for testing volatile compounds.
Some of the preparation methods described in this document might not be accepted by regulators for making conclusions on the ready biodegradability of tested compounds.
Examples of biodegradability curves are given in Annex A.
Wasserbeschaffenheit - Vorbereitung und Behandlung von in Wasser schwer löslichen organischen Verbindungen für die nachfolgende Bestimmung ihrer biologischen Abbaubarkeit in einem wässrigen Medium (ISO 10634:2018)
Dieses Dokument beschreibt Techniken zur Vorbereitung schwer wasserlöslicher Verbindungen (d. h. flüssige und feste Verbindungen) mit einer Wasserlöslichkeit von weniger als etwa 100 mg/l und zu ihrer Einbringung in Testgefäße zur nachfolgenden Prüfung auf biologische Abbaubarkeit in einem wässrigen Medium mittels genormter Verfahren.
Bei den nachfolgenden Tests auf biologische Abbaubarkeit handelt es sich in erster Linie um Verfahren zur Bestimmung des freigesetzten Kohlenstoffdioxids (siehe ISO 9439) und zur Bestimmung des Sauerstoffverbrauchs (siehe ISO 9408) unter Anwendung der üblichen Vorkehrungen nach ISO 10707. Verfahren, bei denen der Abbau von gelöstem organischem Kohlenstoff (DOC) (en: dissolved organic carbon) gemessen wird, eignen sich nicht.
In diesem Dokument werden keine Abbautestverfahren beschrieben. Es beschränkt sich auf die Beschreibung der Techniken zur Einbringung der Testsubstanzen in das Testmedium und zur Aufrechterhaltung des dispergierten Zustands [4]. Wenn diese Techniken angewendet werden, müssen die experimentellen Bedingungen, die in den genormten Abbauverfahren beschrieben sind, eingehalten werden. ISO 9439, bei dem die CO2 Entwicklung gemessen wird, ist für die Prüfung leichtflüchtiger Verbindungen nicht geeignet.
Einige der in diesem Dokument beschriebenen Vorbereitungsverfahren werden möglicherweise von Zulassungsbehörden für die abschließende Beurteilung der leichten biologischen Abbaubarkeit der geprüften Substanzen nicht akzeptiert.
Beispiele für Abbaukurven enthält Anhang A.
Qualité de l'eau - Préparation et traitement des composés organiques peu solubles dans l'eau en vue de l'évaluation de leur biodégradabilité en milieu aqueux (ISO 10634:2018)
Le présent document spécifie des méthodes de préparation de composés organiques peu solubles dans l'eau (c'est-à-dire, des composés liquides et solides) ayant une solubilité dans l'eau inférieure à environ 100 mg/l et leur introduction dans des récipients d'essai, en vue de réaliser un essai de biodégradabilité en milieu aqueux selon des méthodes normalisées.
Les essais de biodégradabilité applicables sont des méthodes utilisant l'analyse du dioxyde de carbone dégagé décrite dans l'ISO 9439 et la détermination de la demande en oxygène décrite dans l'ISO 9408 et respectant les précautions habituelles de l'ISO 10707. On peut ainsi noter que les méthodes de mesure de l'élimination du carbone organique dissous (COD) ne sont pas appropriées.
Le présent document ne décrit pas les méthodes d'essai de biodégradation. Il se limite à la description des méthodes d'introduction des composés d'essai dans le milieu d'essai et à leur maintien à l'état dispersé.[4] Ces méthodes sont mises en œuvre en respectant les conditions expérimentales décrites dans les méthodes normalisées pour l'évaluation de la biodégradabilité. L'ISO 9439, qui repose sur le dégagement de CO2, ne convient pas pour soumettre à essai les composés volatils.
Certaines des méthodes de préparation décrites dans le présent document peuvent ne pas être acceptées par les organismes de réglementation pour tirer des conclusions au sujet de la facilité de biodégradabilité des composés d'essai.
Des exemples de courbes de biodégradabilité sont donnés en Annexe A.
Kakovost vode - Priprava in obdelava v vodi slabo topnih organskih spojin za nadaljnje vrednotenje njihove biorazgradljivosti v vodi (ISO 10634:2018)
Ta dokument določa tehnike za pripravo v vodi slabo topnih organskih spojin (tj. spojin v tekočem in trdnem stanju), s topnostjo v vodi manj kot približno 100 mg/l, in njihovo vnašanje v preskusne posode za naknadni preskus biorazgradljivosti v vodnem mediju s standardnimi metodami.
Nadaljnji preskusi biorazgradljivosti so predvsem metode z uporabo analize sproščenega
ogljikovega dioksida, opisane v standardu ISO 9439, in določevanje kisika, opisano v standardu ISO 9408, ob upoštevanju običajnih varnostnih ukrepov v skladu s standardom ISO 10707. Tako lahko opazimo, da metode za merjenje odstranitve raztopljenega organskega ogljika (DOC) niso ustrezne.
Ta dokument ne določa metod za preskušanje biorazgradnje. Omejen je na opisovanje
tehnik za vnašanje preskusnih spojin v preskusni medij in njihovo vzdrževanje v razpršenem stanju [4]. Te tehnike se izvajajo ob upoštevanju preskusnih pogojev, opisanih v standardiziranih metodah za vrednotenje biorazgradljivosti. Standard ISO 9439, ki temelji na nastajanju CO2, ni primeren za preskušanje hlapnih spojin.
Nekaterih metod za pripravo, opisanih v tem dokumentu, regulatorji morda ne bodo sprejeli za sklepanje o lahki biorazgradljivosti preskušenih spojin.
Primeri krivulj biorazgradljivosti so podani v dodatku A.
