12、7755-4.3.1:1994 ii BSI 09-1999 National foreword This Subsection of BS 7755 has been prepared under the direction of the Environment and Pollution Standards Policy Committee. It is identical with ISO 11269-1:1993 Soil quality Determination of the effects of pollutants on soil flora Part 1: Method fo
13、r the measurement of inhibition of root growth, published by the International Organization for Standardization (ISO). ISO 11269-1 was prepared by Subcommittee 4, Biological methods, of Technical Committee ISO/TC 190, Soil quality, with the active participation and approval of the UK. BS 7755 is bei
14、ng published in a series of Parts subdivided into Sections and Subsections that will generally correspond to particular International Standards. Other Parts of BS 7755 are, or will be, as follows. Part 1: Terminology and classification; Part 2: Sampling; Part 3: Chemical methods; Part 4: Biological
15、methods; Part 5: Physical methods. Section 4.3 of BS 7755-4 is one of a group of standards dealing with biological tests on soil. Other Sections in this Part are, or will be, as follows. Section 4.1: Biodegradability; Section 4.2: Effects of pollutants on soil fauna; Section 4.4: Effects of pollutan
16、ts on soil microorganisms. Section 4.3 is, or will be, divided into the following Subsections. Subsection 4.3.1: Method for the measurement of inhibition of root growth; Subsection 4.3.2: Method for the measurement of effects of chemicals on the emergence and growth of higher plants; Subsection 4.3.
17、3: Method for the measurement of germination; Subsection 4.3.4: Guidance on field testing using higher plants. Cross-references The Technical Committee has reviewed the provisions of the draft of ISO 11274, to which normative reference is made in the text, and has decided that they are acceptable fo
18、r use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

21、 of the suitability or otherwise of the soil for arable production, or the potential environmental risk resulting from the disposal of wastes such as sewage sludge on farmland. There is also a need to assess the quality of soil after reclamation of industrial sites and colliery tips or when capping
22、landfill sites. As the ability of the soil to grow crops is the main criterion, a rapid growth test has been developed based on seedling growth in controlled environmental conditions. Two major prerequisites of a phytotoxicity test are that it provides consistently reliable results and that it can b
23、e used at any time of the year. It is therefore essential to raise seeds in a controlled environment to ensure optimal growing conditions which can be maintained for any number of tests, producing reproducible results over a long period of time. The test method described in this part of ISO 11269 ma
24、y be used to compare soils, to monitor changes in their activity or to determine the effect of added substances. 1 Scope This part of ISO 11269 describes a preliminary test for the rapid estimation of soil quality by comparing the rate of growth of roots of a specified plant under standard condition
