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.

This document specifies a method for the measurement of several hydrolase activities (arylamidase, arylsulfatase, ß-galactosidase, a-glucosidase, ß-glucosidase, N-acetyl-glucosaminidase, acid, alkaline and global phosphatases, urease) simultaneously (or not) in soil samples, using colorimetric substrates. Enzyme activities of soil vary seasonally and depend on soil chemical, physical and biological characteristics. This method can be applied either to detect harmful effects on soil enzyme activities derived from toxic substances or other anthropogenic agents in contaminated soils against a control soil, or to test chemicals.

This document specifies a protocol to identify ecotoxicological test specimens (mainly invertebrates and plants) to the species level, based on the DNA barcoding technique. This protocol can be used by laboratories performing DNA barcoding in order to standardize both the wet-lab and data analysis workflows as much as possible, and make them compliant with community standards and guidelines.This document does not intend to specify one particular strain for each test method, but to accurately document the species/strain which was used.NOTE 1 This does not imply that DNA barcoding is performed in parallel to each test run, but rather regularly (e.g. once a year, such as reference substance testing) and each time a new culture is started or new individuals are added to an ongoing culture.This document does not aim at duplicating or replacing morphological-based species identifications. On the contrary, DNA barcoding is proposed as a complementary identification tool where morphology is inconclusive, or to diagnose cryptic species, in order to ensure that the results obtained from different ecotoxicological laboratories are referring to the same species or strain.This document is applicable to identifications of immature forms which lack morphological diagnostic characters (eggs, larvae, juveniles), as well as the streamline identification of specimens collected in field monitoring studies, where large numbers of organisms from diverse taxa are classified.NOTE 2 In principle, all species regularly used in ecotoxicological testing can be analysed by DNA barcoding. Besides the earthwoms Eisenia fetida and E. andrei, further examples for terrestrial species are Lumbricus terrestris, L. rubellus, Allolobophora chlorotica, Aporrectodea rosea, and A. caliginosa, Dendrodrilus rubidus, Enchytraeus albidus, and E. crypticus (Haplotaxida); Folsomia candida, F. fimetaria, Proisotoma minuta, and Sinella curviseta (Collembola); Hypoaspis aculeifer and Oppia nitens (Acari); Aleochara bilineata and Poecilus cupreus (Coleoptera); Scathophaga stercoraria, Musca autumnalis (Diptera) or Pardosa sp. (Arachnida). Nematodes or snails and even plants can also be added to this list.

This document describes a method to compare the quality of soils by determining the fatty acid composition of the leaves of plant species grown in these soils.This method does not make it possible to determine an optimal value of the Omega-3 index and, therefore, cannot be used to determine the intrinsic quality of a soil from a specific area (regarded as homogeneous). The method can only be used to compare the quality of soils between various areas.This method is applicable to:— soils from contaminated sites;— amended soils;— soils after remediation;? soil with waste products (e.g. slurry, manure, sludge or composts).Alternatively, the quality of soils can be assessed by determining the Omega-3 index of Lactuca sativa seedlings grown in these soils under controlled conditions (i.e. phytotronic chamber) and by comparing these values to those obtained from control soils (see Annex B).

The purpose of ISO 29200:2013 is to describe a method for assessing genotoxic effects (chromosome breakage or dysfunction of the mitotic spindle) of soils or soil materials on the secondary roots of a higher plant: Vicia faba (broad bean). This method allows the assessment of genotoxicity (toxicity for genetic material) of soils and soil materials like compost, sludge, waste, fertilizing matters, etc. Two ways of exposure can be considered: a direct exposure of plants to the soil (or soil material) which is relevant for the real genotoxic potential and an exposure of plants to the water extract of the soil (or soil material). This last way of exposure to a leachate or an eluate allows the detection of the mutagens which are not adsorbed to soils and which may be transferred to aquatic compartments. Moreover, this test may be used to evaluate genotoxic effects of chemical substances and to waters, effluents, etc.

This International Standard specifies a rapid method for the determination of the potential rate of ammoniumoxidation and inhibition of nitrification in soils. This method is suitable for all soils containing a population ofnitrifying microorganisms. It can be used as a rapid screening test for monitoring soil quality and quality ofwastes, and is suitable for testing the effects of cultivation methods, chemical substances [except volatiles,i.e. H > 1 (Henry’s constant)], extracts of biosolids and pollution in soils.

ISO 17512-2:2011 specifies a rapid screening method for evaluating the habitat function of soils based on the avoidance behaviour of springtails.The test is a rapid method that reflects the bioavailability of contaminants in natural soils and substances spiked into soils to Folsomia candida. In both cases, it is possible to establish a dose-response-relationship. The avoidance behaviour of the springtails is the measurement endpoint of the test. This test is not intended to replace the Collembola reproduction test.

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.

This document specifies a chronic test method for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Hypoaspis aculeifer by ? mainly ? alimentary uptake. This method is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, industrial, agricultural or other sites under concern and waste materials (e.g. dredged material, municipal sludge from a wastewater treatment plant, composed material, or manure, especially those for possible land disposal). The reproduction (= number of juveniles) is the measured parameter of the test. The test reflects the bioavailability of a mixture of contaminants in natural soils (contaminated site soils) to a species which represents a trophic level which is not covered by other ISO standards. This test is not intended to replace the earthworm (see ISO 11268-2) or Collembola (see ISO 11267) reproduction tests since this species belongs not only to a different trophic group but also a different taxonomic group (= mites; i.e. arachnids) than those used usually.Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects are determined in the soil to be tested and in a control soil. Depending on the objective of the study, the control and dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (reference soil) or a standard soil (e.g. artificial soil).This document provides information on how to use this method for testing samples (soils or substances) under temperate conditions.This document is not applicable to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa at 25 °C.NOTE The stability of the test substance cannot be ensured over the test period. No provision is made in the test method for monitoring the persistence of the substance under test.

ISO 17512-1:2008 specifies a rapid screening method for evaluating the habitat function of soils and the influence of contaminants and chemicals on earthworm behaviour.The sublethal test is a rapid method that reflects the bioavailability of contaminant mixtures in natural soils and substances spiked into soils to Eisenia fetida and Eisenia andrei. The avoidance behaviour of the worms is the measurement endpoint of the test. This test is not intended to replace the earthworm reproduction test.Two different designs (a two section unit and a six section unit) have been developed and successfully applied. Both designs are applicable to either single-concentration (e. g. for assessing the quality of a field soil) or multi-concentration (e. g. for assessing the toxicity of a spiked chemical) tests. In both cases, the earthworms are allowed to make the initial choice on which compartment, control and a treatment [in the two section test vessel between right and left side; in the six section test vessel between the (3 + 3) alternating compartments], to enter.
