Soil quality - Effects of pollutants on insect larvae (Oxythyrea funesta) - Determination of acute toxicity (ISO 20963:2005)

ISO 20963:2005 describes a method for the determination of the effects of contaminated soils and substances on the survival of the larvae of Oxythyrea funesta. The larvae are exposed to the pollutants by cuticular and alimentary uptake.
For contaminated soils, the effects on the survival are determined in the test soil and in a control soil. Depending on the objectives of the study, the control and dilution substrates (dilution series of contaminated soil) are either uncontaminated soil comparable to the soil sample to be tested or artificial soil substrate. Effects of substances are assessed using a defined artificial soil substrate.
ISO 20963:2005 is not applicable to volatile substances, i.e. substances for which Henry's constant or the air/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0,001 33 Pa at 25 °C.
This method does not take into account the possible degradation of the substances or pollutants during the test.

Bodenbeschaffenheit - Auswirkungen von Schadstoffen auf Insektenlarven (Oxythyrea funesta) - Bestimmung der akuten Toxizität (ISO 20963:2005)

Diese Internationale Norm beschreibt ein Verfahren zur Bestimmung der Wirkungen von verunreinigten Böden und von Substanzen auf das Überleben der Larven von Oxythyrea funesta. Die Larven werden den Schadstoffen bei Aufnahme über die Haut und die Nahrung ausgesetzt.
Bei verunreinigten Böden werden die Wirkungen auf das Überleben im Prüfboden und in einem Kontrollboden bestimmt. In Abhängigkeit von der Zielsetzung der Untersuchung sind die Kontrolle und das zum Verdünnen verwendete Substrat (Verdünnungsreihen des verunreinigten Bodens) entweder ein mit der zu prüfenden Bodenprobe vergleichbarer, nicht verunreinigter Boden oder ein künstliches Bodensubstrat. Die Wirkungen von Substanzen werden mit einem festgelegten künstlichen Bodensubstrat bewertet.
Diese Internationale Norm ist nicht auf flüchtige Substanzen anwendbar, d. h. Substanzen, bei denen die Henry-Konstante oder der Luft/Wasser-Verteilungskoeffizient größer als 1 ist, oder bei denen der Dampfdruck bei 25 °C 0,001 33 Pa überschreitet.
ANMERKUNG Dieses Verfahren berücksichtigt nicht den möglichen Abbau der Substanzen oder Schadstoffe während der Prüfung.

Qualité du sol - Effets des polluants vis-à-vis des larves d'insectes (Oxythyrea funesta) - Détermination de la toxicité aiguë (ISO 20963:2005)

L'ISO 20963:2005 décrit une méthode de détermination des effets des sols contaminés et des substances sur la survie des larves de Oxythyrea funesta. Les larves sont exposées aux polluants par absorption cuticulaire et ingestion.
Pour les sols contaminés, les effets sur la survie sont déterminés dans le sol soumis à essai et dans un sol témoin. Selon l'objectif de l'étude, le substrat utilisé pour le témoin et les dilutions (série de dilutions du sol contaminé) sont soit un sol non contaminé comparable à l'échantillon de sol à soumettre à essai, soit un substrat de sol artificiel. Les effets des substances sont évalués en utilisant un substrat de sol artificiel défini.
L'ISO 20963:2005 n'est pas applicable aux substances volatiles, c'est-à-dire des substances pour lesquelles la constante de Henry ou le coefficient de partition air/eau est supérieur à 1, ou des substances pour lesquelles la pression de vapeur excède 0,001 33 Pa à 25 °C.
Cette méthode ne prend pas en compte la dégradation possible des substances ou des polluants au cours de l'essai.

Kakovost tal - Vpliv onesnaževal na ličinke žuželk (Oxythyrea funesta) - Določevanje akutne strupenosti (ISO 20963:2005)

Ta mednarodni standard opisuje metodo za ugotavljanje učinkov onesnaženih tal in snovi na preživetje ličink žuželke Oxythyrea funesta. Ličinke so izpostavljene onesnaževalom prek epidermijskega in prehranskega vnosa. Pri onesnaženih tleh se učinki na preživetje določajo v preskusnih in kontrolnih tleh. Odvisno od namenov raziskave so kontrolni in razredčeni substrati (serija razredčitev onesnaženih tal) bodisi neonesnažena tla v primerjavi z vzorcem preskušanih tal ali umetni talni substrat. Učinki snovi se ocenjujejo z uporabo opredeljenega umetnega talnega substrata. Ta mednarodni standard ne velja za hlapne snovi, tj. snovi, pri katerih je Henryjeva konstanta ali porazdelitveni koeficient zrak/voda večji od 1 ali pri katerih parni tlak presega 0,001 33 Pa pri 25 °C.

ISO 20963:2005(E)
Foreword
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 20963:2005(E)
Introduction
This International Standard describes a method for the determination of the acute toxicity of contaminated
soils and chemicals to the larvae of Oxythyrea funesta, a phytophagous coleopteran (Scarabaeidae,
Cetoniinae) with wide geographic distribution (Europe, North Africa and the Middle East).
Oxythyrea funesta has many characteristics which make it suitable for soil quality monitoring or testing effects
of chemicals:
 ecological relevance: this type of organism contributes in many ways to soil structure by stimulating soil
aeration and drainage;
 the first stages of development, i.e. incubation of eggs, larval cycle and pupation, are underground;
 the larvae of Oxythyrea funesta are tolerant to modifications of the test substrate granulometry;
 this species can be bred under controlled conditions.

funesta) — Determination of acute toxicity
1 Scope
This International Standard describes a method for the determination of the effects of contaminated soils and

cuticular and alimentary uptake.
For contaminated soils, the effects on the survival are determined in the test soil and in a control soil.
Depending on the objectives of the study, the control and dilution substrates (dilution series of contaminated
soil) are either uncontaminated soil comparable to the soil sample to be tested or artificial soil substrate.
Effects of substances are assessed using a defined artificial soil substrate.
This International Standard is not applicable to volatile substances, i.e. substances for which Henry’s constant
or the air/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0,001 33 Pa at
25 °C.
NOTE This method does not take into account the possible degradation of the substances or pollutants during the
test.
