This standard describes a method to compare the quality of soils by determining the fatty acid composition of the leaves of plant species grown on these soils. Because plant fatty acid composition can vary as functions of climatic conditions, the areas to compare must share the same climatic conditions (humidity, temperature, sunlight). 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 (regard as homogeneous). The method can be only used to compare the quality of soils between various areas. This method is applicable to: The Omega-3 index being an early indicator, its measurement is not relevant when a strong visual phenotype (highly reduced biomass, high leaf chlorosis…) is detected for plants having grown on one area, and not detected on another area. Alternatively, the quality of soils can be assessed by determining Omega-3 index of Lactuca sativa seedlings grown on these soils under controlled conditions (i.e. phytotronic chamber) and by comparing it to that obtained on control soils (see Annex A).

This International Standard deals with the assessment of human exposure from ingestion of soil and soil material. This document specifies a physiologically based test procedure for the estimation of the human bioaccessibility of metals from contaminated soil in connection with the evaluation of the exposure related to human oral uptake. Soils or other geological materials, in sieved or crushed form, are extracted in an environment that simulates the basic physicochemical conditions of the human gastrointestinal tract. The test method produces extracts that are representative of the concentration of potentially harmful elements in the human gastrointestinal tract for subsequent chemical characterisation. The test has been validated for arsenic, cadmium and lead in an international inter-laboratory trial. The method is in vivo validated to assess bioaccessibility of As, Sb, Cd and Pb.

This document specifies a method for the determination of total organic carbon (TOC), dissolved organic carbon (DOC), total bound nitrogen (TNb) and dissolved bound nitrogen (DNb) in the form of free ammonia, ammonium, nitrite, nitrate and organic compounds capable of conversion to nitrogen oxides under the conditions described. The procedure is carried out instrumentally. The method is applicable to water samples (e.g. drinking water, raw water, ground water, surface water, sea water or waste water, leachates). The method allows a determination of TOC and DOC = 1 mg/l and TNb and DNb = 1 mg/l. The upper working range is restricted by instrument-dependent conditions (e.g. injection volume). Higher concentrations can be determined after appropriate dilution of the sample. For samples containing volatile organic compounds (e.g. industrial waste water), the difference method is used, see Annex A. Cyanide, cyanate and particles of elemental carbon (soot), when present in the sample, can be determined together with the organic carbon. The method is not appropriate for the determination of volatile, or purgeable, organic carbon under the conditions described by this method. Dissolved nitrogen gas (N2) is not determined. Details of the interlaboratory trial are given in Annex B.

This part of ISO 18400 gives guidance on the: Although the information on soil quality for the risk assessment and/or the development of remedial action plans is gathered by applying this part of ISO 18400, this document does not give guidance on the decisions and actions that follow from a site investigation, for example, risk assessment and decisions about the requirements for remediation (if any), although other International Standards could be helpful in this regard (see 4.1).

This part of ISO 18400 provides guidance on the sampling of soils of: It is applicable to: This document sets out appropriate strategies for the design of sampling programmes, field procedures and subsequent treatment of samples for transport and storage prior to sample pretreatment (e.g. drying, milling). It should be used in conjunction with the other parts of ISO 18400 as appropriate. In particular, attention should be paid to the requirements concerning collection, handling and storage of soil for assessment of biological functions in ISO 18400-2061).

This European Standard provides guidance on characterizing the modifications of the hydromorphological features of TraC waters described in EN 16503, enabling consistent comparisons of hydromorphological modification between TraC waters within a country and between different countries in Europe. Its primary aim is to assess ‘departure from naturalness’ as a result of human pressures on TraC hydromorphology, and it suggests suitable sources of information that may contribute to describing the modification of hydromorphological features. The procedures set out in this standard will encourage the objective assessment and reporting of the variability in transitional and coastal waters, and contribute to the work needed to implement the WFD and the MSFD; however, it does not replace methods that have been developed for local assessment and reporting.
