22、ide 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 interested in a subject for which a technical committee has been established has the right to be represented on th
23、at committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in
24、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 technical committees are circulated to the member bodies for voting. Publication as an International Standard r
25、equires 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.

27、l 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 based
28、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 (BMBF),
29、 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.

31、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 incubation. Furthermore, test plants can absorb chemicals from the soil and safety measures should also be consi
32、dered 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 under controlled conditions. Two species are recommended: a rapid-cycling variant of turnip rape (Brassica
33、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 natural test soils, e.g. from contaminated sites or remediated soils, and by comparing the development of the t
34、est 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 modifications allowing use of the chronic plant assay for the testing of chemicals incorporated into soil. B
35、y 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 volatile substances, i.e. substances for which H (Henrys constant) or the air/water partition coefficient is g
36、reater than 1, or for which the vapour pressure exceeds 0,013 3 Pa at 25 C. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、 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 dry mass p
42、er 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 amount of
43、 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 preparing dilut
44、ion 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 soil and a c
45、ontrol 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 a test s
46、oil, 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 fraction) of
47、 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 mass of
48、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 compared with
49、 the control pots.
