19、ation) 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 interested in a subject for which a technical committee has been established has the right to be
20、 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 Commission (IEC) on all matters of electrotechnical standardization.International Standard
21、s 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 technical committees are circulated to the member bodies for voting. Publication as an Internat
22、ional 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.

24、)IntroductionMacroinvertebrates are an important component of fresh-water ecosystems and are the most widely used biological group to monitor aquatic ecological status (Reference 6). A wide range of sampling and survey methodologies has been developed for a variety of specific applications as well a
25、s ecological assessment including: conservation status, biodiversity assessment, pollution control, and habitat enhancement (Reference 7).This International Standard gives guidelines on the selection, design, operation, and performance characteristics of sampling devices for the evaluation of benthi
26、c macroinvertebrate taxonomic composition, abundance, and diversity in fresh waters, which can all be components of the applications given in the first parargraph.

This International Standard does not purport to address the safety problems associated with its use. It is the responsibility of the user to establish appropriate health and safety prac
28、tices and to ensure compliance with any national regulatory conditions.1 ScopeThis International Standard specifies criteria for the selection of sampling methods and devices (operation and performance characteristics) used to evaluate benthic macroinvertebrate populations in fresh waters (rivers, c
29、anals, lakes, and reservoirs). The methods and devices considered in this International Standard are suitable for sampling all major components of the benthic assemblage. They are not suitable for sampling meiofauna.2 Terms and definitionsFor the purpose of this document, the following terms and def

36、number of benthic macroinvertebrates of a species/taxon divided by the total number of benthic macroinvertebrates of all species/taxa, expressed as a percentage)3 Principle3.1 GeneralIn order to evaluate benthic macroinvertebrate population parameters such as taxonomic composition, abundance, and di
37、versity in fresh waters, appropriate sampling devices are required. The choice of the appropriate sampling device depends on the objective of the study itself as well as on the water type and the benthic macroinvertebrate population being studied (Reference 6).Sampling methods are described in this
38、International Standard to cover the broad variety of fresh waters and the diversity of macroinvertebrate taxa and these habitats. The performance characteristics of the devices should be taken into account in order to achieve the best evaluation in the context of the objectives of the survey.3.2 Obj
39、ectivesThe methods given in this International Standard are suitable for a wide variety of objectives. These objectives include: assessment of ecological status, detection of change in surveillance, operational and investigational monitoring programmes, diagnosis of environmental stress, and the ass
40、essment of both acute and chronic stressors (pollution control). The methods are also suitable for conservation and biodiversity assessments with measurement of both community parameters and appraisal of rare species status. Many of the methods are used both routinely and in research studies (Refere
41、nces 61114). Guidance on the analysis of results from benthic macroinvertebrate surveys is given in ISO 8689-13and ISO 8689-2.42 ISO 2012 All rights reservedBS EN ISO 10870:2012ISO 10870:2012(E)3.3 Sampling programmesThe design of a sampling programme depends on the aims of the survey and the requir
42、ed power of discrimination of the data. The programme should be developed with regard to the local topographical and hydrological conditions in the survey area, information on local environmental stressors, and knowledge from previous surveys (if any). The number of sampling stations, their position
43、s, season or seasons of sampling, and the numbers of replicate samples to be taken at each station should be established prior to the initiation of the survey, or through a pilot survey (Reference 6). The design of the programme determines the options for data treatment and statistical analyses that
44、 can be performed; therefore, prior consideration should be accorded to the reporting requirements. Quality assurance of sampling and analysis should also be considered at this stage. Further general guidance on survey design is given in ISO 5667-1.1During the design of the sampling programme, consi
45、deration should be given to the possibility of transferring diseases (e.g. crayfish plague) and the dispersal of non-native invasive species. Appropriate precautionary measures should be included in the operation of any of the devices to prevent such transfers.3.4 Device and method selectionThe meth
46、ods and devices given in this International Standard have been chosen to achieve a good evaluation for the broad variety of inland waters and the diversity of macroinvertebrate taxa. The methods and devices are suitable for routine monitoring and for some research purposes. Methods and devices suita
47、ble only for research purposes have been excluded. Detailed guidance on the design of sampling equipment, the mode of operation and the scope of characteristics can be found in Clause 4. Three main selection criteria have been evaluated in recommending suitable methods/devices for sampling different
48、 habitats. The three criteria are: suitability for operation in flowing or standing fresh waters; suitability for operation in shallow or deep fresh waters; the ability to provide results that are qualitative, quantitative or semi-quantitative.Table 1 indicates which devices are appropriate for each
49、 habitat and in which section each device can be found.4 Benthic macroinvertebrates sampling methods and devices4.1 GeneralBenthic macroinvertebrates may be caught by active sampling or passive sampling (colonization samplers). For all sampling methods, seasonal aspects of macroinvertebrate life cycles should be considered and taken into account. The efficiency of active and passive sampling may also vary depending on the time (day/night) of use; therefore the details of these aspects of use should be record
