Soil quality - Determination of the toxic effects of pollutants on germination and early growth of higher plants (ISO 18763:2016)
ISO 18763:2016 describes a technique for determining the effects of soil and soil-related materials on the seed germination and early growth of higher plants. These endpoints are useful indicators for the assessment of the quality of a soil as a habitat for organisms. It is applicable to all soils in which soil organisms are active and may be used to evaluate:
- the effects on plants due to toxicity of solid or liquid chemicals contaminating soil or materials (compost, sludge, waste) and chemicals added to soil;
- the changes in the soil effect on plants after restoration measures.
Bodenbeschaffenheit - Bestimmung der toxischen Wirkung von Schadstoffen auf die Keimung und das frühe Wachstum höherer Pflanzen (ISO 18763:2016)
Die vorliegende Internationale Norm beschreibt ein Verfahren zur Bestimmung der Wirkungen von Boden und bodenähnlichen Materialien auf die Samenkeimung und das frühe Wachstum höherer Pflanzen. Diese Endpunkte sind nützliche Indikatoren für die Beurteilung der Qualität eines Bodens als Lebensraum für Organismen. Diese Internationale Norm ist auf alle Böden anwendbar, in denen Bodenorganismen aktiv sind, und darf zur Bewertung von Folgendem angewendet werden:
- der Wirkungen auf Pflanzen aufgrund der Toxizität von festen oder flüssigen Chemikalien, die den Boden oder Materialien (Kompost, Schlamm, Abfälle) verunreinigen, und Chemikalien, die dem Boden zugegeben werden;
- der Änderungen der Wirkung des Bodens auf Pflanzen nach Sanierungsmaßnahmen.
Qualité du sol - Détermination des effets toxiques des polluants sur la germination et les premiers stades de croissance des végétaux supérieurs (ISO 18763:2016)
La présente Norme internationale décrit une méthode permettant de déterminer les effets de sols et de matériaux apparentés aux sols sur la germination des semences et les premiers stades de la croissance des végétaux supérieurs. Ces critères d'effet sont des indicateurs utiles pour l'évaluation de la qualité d'un sol en tant qu'habitat pour des organismes. La présente Norme internationale est applicable à tous les sols dans lesquels des organismes sont actifs et peut être utilisée pour évaluer:
— les effets sur les végétaux dus à la toxicité des produits chimiques solides ou liquides polluant les sols ou les matériaux (compost, boues, déchets) ainsi que les produits chimiques ajoutés aux sols;
— les variations dans les effets sur les végétaux du sol après des actions de réhabilitation.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
Ecotoxicological testing of test soils or waste materials to be disposed on soil are required to assess
the potential environmental risk resulting from soil pollution or the disposal of wastes such as sewage
sludge on farmland. There is also a need to monitor the quality of soil after reclamation of industrial
sites. Therefore, a very practical and rapid germination and growth test has been developed based on
seed germination and seedling growth in controlled environmental conditions.
The assay, which does not require any pretreatment of the seeds, is performed in “transparent test plates”,
incubated vertically, to allow the roots and the shoots of the germinated seeds to be seen. After 72 h
exposure, a picture of the transparent test plates is taken and can be analysed “by image analysis” for
multiple endpoints, such as percentage of seed germination and of length of roots and shoots. To account
for the plant species variability in sensitivity, the assays are performed with the seeds of three plant
species: one monocotyl (Sorghum saccharatum) and two dicotyls (Lepidium sativum and Sinapis alba).
A major advantage of this test is that after the shooting and storing of the pictures of the test plates, the
measurements by image analysis can be postponed to any appropriate timing.
Reference or standard soils can be used as negative controls, such as, for example, the ISO standard
artificial soil according to ISO 11269-1 and ISO 11269-2.
Commercially available seeds, with a shelf life longer than one year, allow the use of this test at any time
of the year.
Two International interlaboratory comparisons demonstrated that the test provides good results.
A substantial number of studies report data on the application of this test on various types of soils and
soil materials with several types of plant species.
