DIN EN ISO 22030:2011-09 EN ISO 22030:2011 (E) 3 Introduction This International Standard describes a procedure for evaluating the quality of
28、 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 on emergence, vegetative growth and reproductive capacity of a
29、t 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), Bonn 3, and b) discussions within the joint project “Ecotoxic
30、ological Test Batteries” forming part of the BMBF Joint Research Group “Processes for the Bioremediation of Soil” 10. DIN EN ISO 22030:2011-09 EN ISO 22030:2011 (E) 4 WARNING Contaminated soils can contain unknown mixtures of toxic, mutagenic or otherwise harmful chemicals or infectious microorganis
31、ms. 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 considered when handling these test plants. 1 Scope This International Standard describes a method
32、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 rapa CrGC syn. Rbr) and oat (Avena sativa). The duration of test should be sufficient to inclu
33、de 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 test plants in these soils with reference or standard control soils, the test can be used to as
34、sess 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. By preparing a dilution series of a test substance in standard control soils, the same endpoint
35、s 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 greater than 1, or for which the vapour pressure exceeds 0,013 3 Pa at 25 C. 2 Normative refere

40、l soil mixture of sand, kaolinite, peat and calcium carbonate 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 Bioma
41、ss is expressed as dry mass per plant or, if needed, as dry 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 gro
42、wth period. 3.3 concentration mass of test substance per 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 uncontamina
43、ted substrate, used as a control and as medium for preparing 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 an
44、y case, differences in nutrient levels between a test soil 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 te
45、st plants). If a control soil is poorer in nutrients than 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 nutri
46、ents. 3.6 effect concentration ECxconcentration (mass fraction) 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,
47、the ECxis expressed as mass of the test substance per dry 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 pe
48、rcentage of seedlings which emerge from test pots as compared with the control pots. DIN EN ISO 22030:2011-09 EN ISO 22030:2011 (E) 6 3.8 habitat function ability of soils/soil materials to serve as a habitat for microorganisms, plants, soil-living animals and their interactions (biocenosis) ISO 157
49、99 3.9 hormesis improvement of seedling emergence, growth or survival (or other response of the test plants) at low concentrations of chemicals or mixtures of soil that are toxic when applied at higher levels in comparison to the control 13.10 lowest observed effect concentration LOEC lowest tested concentration (mass 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.
