This document specifies a method for quantitative determination of 17 2,3,7,8-chlorine substituted dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls in sludge, treated biowaste and soil using liquid column chromatographic clean-up methods and gas chromatography/high resolution mass spectrometry (GC/HRMS). Detection by tandem mass spectrometry (MS/MS) can be used in an equivalent way. The analytes that can be determined with the method specified in this document are listed in Table 1. The limit of detection depends on the kind of sample, the congener, the equipment used and the quality of chemicals used for extraction and clean-up. Under the conditions specified in this document, limits of detection better than 1 ng/kg (expressed as dry matter) can be achieved. This method is “performance based”. The method can be modified if all performance criteria given in this method are met. This document is applicable for several types of matrices and validated for municipal sludge (see also Annex D for the results of the validation). NOTE In principle, this method can also be applied for sediments, mineral wastes and for vegetation. It is the responsibility of the user of this document to validate the application for these matrices. For measurement in complex matrices such as fly ashes adsorbed on vegetation, it can be necessary to further improve the clean-up. This can also apply to sediments and mineral wastes.

This document provides a generic description of the methods available for measuring soil characteristics and indicators of core ecological soil functions. No distinction of context is made, i.e. no differentiation of land use and management (e.g agricultural, forest, urban, natural or contaminated lands). For each ecological soil function, the document specifically lists biotic and abiotic characteristics that can be measured. It focuses on characteristics and indicators that are either available as ISO documents or published in peer-reviewed papers. This document applies to ecological soil functions and is not applied to soil functions such as geotechnical functions (foundation support for buildings, tunnels, etc.) or geothermal functions. Indeed, ecosystem services do not address soils without a topsoil, or with a covered topsoil (buildings, infrastructure, greenhouse farming, solar panel parks). Methods and indicators for ecological soil functions can help in the assessment of soil-related ecosystem services but the overall assessment of ecosystem services is not covered in this document. Other methods based on proxy indicators (e.g. soil occupation, hydrography parameters) can also be used for land planning at large scale. These indicators are not included in this document.

This document is suitable to rapidly assess the activity of artificial and natural radionuclides deposited on or present in soil layers of large areas of a site under investigation.
This document can be used in connection with radionuclide measurements of soil samples in the laboratory (see ISO 18589-3) in the following cases:
—     routine surveillance of the impact of radioactivity released from nuclear installations or of the evolution of radioactivity in the region;
—     investigations of accident and incident situations;
—     planning and surveillance of remedial action;
—     decommissioning of installations or the clearance of materials.
It can also be used for the identification of airborne artificial radionuclides, when assessing the exposure levels inside buildings or during waste disposal operations.

This document deals with the assessment of human exposure to metals and metalloids from ingestion of soil. It specifies a simplified method for the prediction of the oral bioaccessibility of metals and metalloids from contaminated soils. The method is a chemical extraction using hydrochloric acid (HCl) and can be used at least for first-tier screening for prediction of the oral bioaccessibility of arsenic (As), cadmium (Cd) and lead (Pb) in soil samples. It produces extracts that are representative of the bioaccessible concentrations measured by using the validated unified bioaccessibility method (UBM) (ISO 17924). More specifically, from the extractable concentrations of metals and metalloids by HCl, the predicted bioaccessibility in both the gastric and gastrointestinal phases is calculated using the equations and the prediction intervals provided in this document, and which have been derived from simple linear regressions of data obtained during validation studies.[ REF Reference_ref_2 \r \h 2 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000100000005200650066006500720065006E00630065005F007200650066005F0032000000 ] NOTE The simplified method is applicable to prediction of the metals and metalloids bioaccessibility in soil with total concentrations range from 2 mg/kg to 2 600 mg/kg for As, from 0,2 mg/kg to 480 mg/kg for Cd, and from 4 mg/kg to 50 000 mg/kg for Pb.

The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract.
Under the conditions specified in this document, lower limit of application from 1 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 10 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples the limit of 10 μg/kg cannot be reached.
Sludge, waste and treated biowaste may differ in properties, as well as in the expected contamination levels of PCB and presence of interfering substances. These differences make it impossible to describe one general procedure. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used.
NOTE            The analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to in EN 61619, EN 12766-1 and ISO 6468 respectively.
The method can be applied to the analysis of other PCB congeners not specified in the scope, provided suitability is proven by proper in-house validation experiments.

This document specifies a method for the differentiated determination of the organic carbon content (TOC400) which is released at temperatures up to 400 °C, the residual oxidizable carbon (ROC) (including e.g. lignite (brown coal), hard coal, charcoal, black carbon, soot) and the inorganic carbon (TIC900) which is released at temperatures up to 900 °C. The basis of this method is the dry combustion or decomposition of carbon to CO2 in the presence of oxygen or non-oxygen conditions using temperatures ranging from 150 °C to 900 °C in dry solid samples of sediment, soil, soil with anthropogenic admixtures and solid waste (see Table 1) with carbon contents of more than 1 g per kg (0,1 % C) (per carbon type in the test portion). NOTE TIC900’ includes the TIC measured after acid addition e.g. by ISO 10694 or EN 15936. TOC400 is a fraction of TOC measured according to e.g. ISO 10694 or EN 15936.

This document provides requirements and guidance on key aspects of remediation techniques. It describes the principles, main characteristics, advantages and limitations to be considered in the selection within an option appraisal of individual or combinations of in situ and on-site remediation techniques, including:
—     the type of contaminants to be dealt with;
—     current and/or intended site use;
—     local legal, policy, socio-economic and environmental contexts.
This document is applicable to the remediation of contaminated sites, i.e. where soil, or soil gas, ambient air or groundwater are contaminated. It identifies which phase/matrix can be targeted by a technique, e.g. fluid (groundwater, gas, non-aqueous phase liquid) or solid, and which contaminant it can applied to. This document also provides information on hazards that can be associated with the implementation of remediation.
This document does not provide:
—     an exhaustive list of remediation techniques;
—     guidance on sites contaminated with radioactive substances, pathogenic or infectious agents, or “pyrotechnic devices” (e.g. unexploded ordnances);
—     guidance on ex situ techniques that are set up off-site;
—     a framework that covers all individual situations, or prescribes which technique(s) to use in a specific context.

This document specifies a rapid method for assessing solid samples in an aerobic suspension, by determining the inhibition of dehydrogenase activity of Arthrobacter globiformis using the redox dye resazurin.
It is applicable for assessing the effect of water-soluble and solid matter bounded non-volatile contaminants in natural samples, such as soils and waste materials. Although not the main purpose, the contact test can additionally be used for testing the effect of chemicals, as described in the Annex C. The test yields a result within 6 h and can therefore be used for screening potentially contaminated test material.

This document specifies the crucial steps of a quantitative real-time polymerase chain reaction (qPCR) method to quantify the abundance of specific mRNA molecules extracted from Daphnia magna.
The method allows the identification of molecular responses to exposures for potentially toxic substances through the analysis of the abundance of specific mRNA molecules. In this document, the central genes involved in reproductive and toxic responses are included.
NOTE   The selection of genes can be adapted to specific exposure conditions, for example, exposure to known toxic substances, by adding genes known to respond to a specific insult.
The present method allows for rapid, robust and sensitive detection of molecular responses and can be used to analyse the toxic effects of water leachates from soil and waste. The method gives information of the concentration of a substance or test-liquid at which toxic effects begin to occur prior to observations of reproductive or toxic effects at higher levels of organization, which reduces the need for the use of safety factors in toxicity assessment.
The method is useful in several types of risk assessment. In this document, the genes studied are appropriate for the assessment of the risks when recycling materials and for the classification of waste, but the method can be adapted to other types of risk assessment by including other genes.
