24、s a procedure for evaluating the quality of soils of different origin carrying unknown contaminations. The evaluation of the effects on plant growth is based on emergence and inhibitory effects on early growth of at least two species of higher plants. Guidance for assessing potential effects of subs

25、tances on seedling emergence and growth is given in OECD Guideline 20814.This part of ISO 11269 refers closely to ISO 22030 and is based on:a) results from the German research project “Entwicklung eines innovativen und technischen Instrumentariums zur Optimierung der kotoxikologischen Bewertung von

26、Bden im Hinblick auf Sanierungsziele und Schutzerfordernisse”;b) discussions within the joint project “Ecotoxicological Test Batteries” forming part of the BMBF Joint Research Group “Processes for the Bioremediation of Soil”23;c) results from the BMBF Joint Research Group ERNTE “Erprobung und Vorber

27、eitung einer praktischen Nutzung kotoxikologischer Testsysteme”17;d) ring-test results of “Ecotoxicological Characterisation of Waste Results and Experiences from an International Ring Test”8.Plant growth can be influenced strongly by soil properties such as texture, pH or levels of nutrients. When

28、testing natural soils either reference soils (uncontaminated soils with the same properties as the test soil) or standard soils are used as mixing and control substrate. In the latter case, variations in plant growth can result from either soil contaminants or differences in soil properties like nut

29、rients and texture. Therefore, results from soil testing can less easily be interpreted than results from testing of chemicals .BS EN ISO 11269-2:2013 ISO 11269-2:2012 (E)Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networkin

Furthermore, test plants might take up chemicals from the soil and safety measures should also be considered when handling the test plants.1 ScopeThis part of IS

32、O 11269 describes a method to assess the quality of an unknown soil and the soil habitat function by determining the emergence and early growth response of at least two terrestrial plant species compared to reference or standard control soils. It is applicable to soils of unknown quality, e.g. from
