20、 SO 5002 All irthgs ersedevrForeword 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 intereste

21、d 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 Com

22、mission (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 techni

23、cal 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 sh

25、ational Standard describes a procedure for evaluating the quality of soils of different origin carrying unknown contaminations. The method, slightly modified, can also be used to measure the toxicity of known chemicals incorporated into soil. The evaluation of the inhibition and chronic toxicity is

26、based on emergence, vegetative growth and reproductive capacity of at least two species of higher plants. This International Standard is based on: a) results of the research project “Development of a chronic bioassay using higher plants”, sponsored by the German Ministry for Education and Research (

27、BMBF), Bonn 3, and b) discussions within the joint project “Ecotoxicological Test Batteries” forming part of the BMBF Joint Research Group “Processes for the Bioremediation of Soil” 10.

28、r 1Soil quality Biological methods Chronic toxicity in higher plants WARNING Contaminated soils can contain unknown mixtures of toxic, mutagenic or otherwise harmful chemicals or infectious microorganisms. Occupational health risks can arise from dust or evaporated chemicals during handling and incu

29、bation. Furthermore, test plants can absorb chemicals from the soil and safety measures should also be considered when handling these test plants. 1 Scope This International Standard describes a method for determining the inhibition of the growth and reproductive capability of higher plants by soils

30、 under controlled conditions. Two species are recommended: a rapid-cycling variant of turnip rape (Brassica rapa CrGC syn. Rbr) and oat (Avena sativa). The duration of test should be sufficient to include chronic endpoints that demonstrate the reproductive capability of the test plants. By using nat

31、ural test soils, e.g. from contaminated sites or remediated soils, and by comparing the development of the test plants in these soils with reference or standard control soils, the test can be used to assess soil quality, especially the function of the soil as a habitat for plants. Annex A describes

32、modifications allowing use of the chronic plant assay for the testing of chemicals incorporated into soil. By preparing a dilution series of a test substance in standard control soils, the same endpoints can be measured to assess the chronic toxicity of chemicals. This method is not applicable to vo

38、nate NOTE ISO 11268-1 describes such a soil for toxicity tests using earthworms. Pure quartz sand, mineral wool, vermiculite or other synthetic substrates should not be used. 3.2 biomass total mass of shoots, flowers and seed pods NOTE 1 Biomass is expressed as dry mass per plant or, if needed, as d

39、ry mass per pot. NOTE 2 During the test period, some of the test plants can reach different growth stages and their water content can differ when the plants are harvested. Thus the dry mass better represents the biomass produced during the growth period. 3.3 concentration mass of test substance per

40、amount of soil NOTE Concentration is expressed as a mass fraction, in milligrams per kilogram (mg/kg) of dry soil. 3.4 contaminant substance or agent present in the soil as a result of human activity ISO 15176:2002 3.5 control soil uncontaminated substrate, used as a control and as medium for prepar

41、ing dilution series with test soils or chemicals, that allows the growth of healthy plants NOTE Either artificial or natural standard or reference soils can be used, if unhindered growth of the test plants in these soils can be expected. In any case, differences in nutrient levels between a test soi

42、l and a control soil can affect the dose-response pattern. For example, a control soil much richer in nutrients than a test soil can result in a false positive result (i.e. the test soil appears to have a “toxic” effect on the growth of the test plants). If a control soil is poorer in nutrients than

43、 a test soil, hormesis (see 3.9) can be expected at low soil-mixture ratios, or even an inverse dose response relationship, if nutrient supply becomes the main effect. This International Standard does not provide numerical values for the nutrients. 3.6 effect concentration ECxconcentration (mass fra

44、ction) of a test chemical or the percentage (mass fraction) of a test soil at which a given endpoint is inhibited by x % compared to the control NOTE The effect concentration is expressed in milligrams per kilogram. When chemicals are tested, the ECxis expressed as mass of the test substance per dry

45、 mass of soil; when soils are tested, the ECxis expressed as a percentage of test soil dry mass per soil mixture dry mass. 3.7 emergence development of a seedling contained within a seed, ending the latent period NOTE It is expressed as the percentage of seedlings which emerge from test pots as comp

46、ared with the control pots.

48、ass fraction) of a test substance in soil at which a statistically significant effect on a given endpoint (p 0,05) compared with the control is observed cf. NOEC (3.11) NOTE Analogously, the term LOEC is used for the lowest tested mixture ratio of a test soil in a reference or a standard control soi

49、l at which a statistically significant effect is observed. The LOEC is expressed as mass of the test substance per mass of dry soil or, in the latter case, as percentage of test-soil dry mass per soil-mixture dry mass. All test concentrations above the LOEC have a harmful effect equal or greater than that observed at the LOEC. If this condition cannot be satisfied, an explanation should be given for how the LOEC and NOEC have been selected. 3.11 no observed effect concentration NOEC test substance concentration (mass frac
