    20、, Uncontrolled Copy, (c) BSIiv 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 intere

    21、sted 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

    22、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 tec

    23、hnical 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

    24、 shall not be held responsible for identifying any or all such patent rights. ISO 19258 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 7, Soil and site assessment.

    26、stances in soils. This International Standard gives guidance on strategies for sampling and data processing and identifies methods for sampling and analysis. This International Standard does not give guidance on the determination of background values for groundwater and sediments. 2 Normative refere

    31、 06:33, Uncontrolled Copy, (c) BSI2 3.4 diffuse source input input of a substance emitted from moving sources, from sources with a large area or from many sources NOTE 1 The sources can be cars, application of substances through agricultural practices, emissions from town or region, deposition throu

    32、gh flooding of a river. NOTE 2 Diffuse source input usually leads to sites that are relatively uniformly contaminated. At some sites, the input conditions may nevertheless cause a higher local input such as near the source or where atmospheric deposition/rain is increased. ISO 11074:2005 3.5 pedo-ge

    37、il sample NOTE For the purpose of analysing spatial variation in soils geostatistically (by estimation of the variogram of a soil property), the support should be the same at each sampling site. 3.11 variate set of observed values of a variable EXAMPLE A variate could for instance be the series of n

    38、umbers of the concentration of a substance in soil or numerous, individual soil samples. BS EN ISO 19258:2011EN ISO 19258:2011 (E)Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 24/11/2011 06:33, Uncontrolled Copy, (c) BSI34 General Soils retain the evidence of their past history including im

    39、pacts due to natural events or human activities. Chemical impacts related to human activities can be detected in soils all over the world, even in regions far from any source of contamination. For this reason, the background contents of inorganic and organic substances in soils consist of a pedo-geo

    40、chemical fraction and an anthropogenic fraction. The ratio of these fractions varies widely depending on the type of substances, the type of soil and land use, and the kind and extent of external impacts. For many inorganic substances, the background content of unpolluted soils is dominated by the p

    41、edo-geochemical content and consequently by the mineralogical composition of the soils parent material. Pedogenetic processes may lead to a redistribution (enrichment/impoverishment) and consequently to a horizon-specific differentiation of the substances within a soil profile. Persistent organic su

    42、bstances in soils originate more often from non-natural sources and therefore the background content of soils is governed by the kind and extent of diffuse contamination from non-soil sources. In practice, it is often difficult to distinguish clearly between the pedo-geochemical and the anthropogeni

    43、c fraction of the background content of soils. Nonetheless, a detailed knowledge of the background content as well as of its natural fraction for the substances of concern is essential both for any evaluation of the current status of soils for environmental or land use related aspects or just for sc

    44、ientific purposes within the scope of pedology or geochemistry. To this end, so-called background values in terms of the statistical characteristics of both, the pedo-geochemical and the anthropogenic fraction have to be determined. A variety of different objectives can be identified for the determi

    45、nation of background values of inorganic and/or organic substances in soils. The objectives themselves provide insufficient information to define the technical programme that will produce the desired background values. Thus a number of technical approaches have to be defined which together form the

    46、basis of the technical programme. This guidance provides essential aspects of sampling strategies and procedures, minimum requirements regarding the necessary steps and ways of sample pre-treatment, analytical methods and statistical evaluation procedures for determining sound and comparable backgro

    47、und values. Guidance is given for a) evaluating existing data from different data sources and b) setting up complete investigation programs aiming to compile background values for a clearly defined three-dimensional picture of the soil. These situations are representing the two extreme starting posi

    48、tions for the process of compiling background values. In practice, a third intermediate situation may be dealt with when additional data need to be collected because the quantity or quality of the existing data is insufficient. 5 Procedures 5.1 General The procedures to determine background values e

    49、ncompass aspects of sampling (strategy, procedure), soil analysis (pre-treatment, extraction and measurement), data processing and presentation. In general, two starting positions can be distinguished, namely a) the evaluation of existing data mostly from different data sources, and b) the collection of new data based on an appropriate investigation strategy.
