20、tal release into the environment, it is important to ensure the validity of a monitoring strategy for testing their behaviour. In this European Standard, monitoring refers both to the monitoring of the occurrence, persistence and/or spread of the GMM and/or the gene(s) involved in the modification a

21、nd its performance in the environment. This European Standard is intended to aid the experimenter in the design of a monitoring strategy appropriate to monitoring objectives. The development of a monitoring valid strategy is directly linked to the development of the sampling strategy as described in

22、 EN 12686. Therefore, this European Standard gives the experimenter a list of points that should be considered in determining the validity of a monitoring strategy comprising valid design, review, execution and documentation of a monitoring protocol. 1 Scope This European Standard provides guidance

23、on factors and criteria considered for the determination of the suitability and validity of the design, development and execution of a monitoring strategy for GMM. Monitoring encompasses detection of genotypic and phenotypic properties, as well as detection of viral material and/or symptoms specific

24、 for the infected host, for the identification of GMMs in an experimental release. This European Standard provides the person conducting a monitoring programme with a list of factors and criteria that should be considered in determining the validity of the proposed strategy for monitoring. This Euro

25、pean Standard is specifically aimed at monitoring experimental release of GMMs or their nucleic acid. This European Standard however, does not cover: the monitoring of virus-like entities or similar agents; the monitoring of GMMs for food, human health and veterinary applications. NOTE Attention is

26、drawn to national, European and international regulations, and relevant standards covering the monitoring of GMMs in food, human health and veterinary applications. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These nor

27、mative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated ref

29、this standard, the following definitions apply: 3.1 analyte substance sought or determined 3.2 behaviour interaction of the organism(s) with abiotic and biotic environments, its (their) occurrence, persistence, multiplication and spreading abilities 3.3 control preparation of known characteristics u

30、sed to standardize an analysis 3.4 detection recognition of the presence of an organism or of a molecular structure within a sample 3.5 genetic modification of interest conceptual design for altering the genetic material within an organism NOTE 1 The genetic modification of interest can be described

31、 at different levels of molecular detail. NOTE 2 The conceptual design can include insertion, substitution or deletion of genetic material. 3.6 genetically modified micro-organism micro-organism in which the genetic material has been altered in a way that does not occur naturally by mating and/or na

32、tural recombination NOTE Within the terms of this definition genetic modification occurs at least through the use of the techniques listed in the Directive 90/219/EEC or its appropriate annexes (see annex B 1). 3.7 genotype genetic constitution of an organism NOTE The genotype can be described with

33、respect to particular genes. 3.8 host target species for virus replication as defined in the experimental designPage 4 EN 12685:1998 BSI 1998 3.9 identification establishment of identity by comparison with a reference NOTE 1 The reference could be an organism, a molecular structure or the genetic mo

34、dification of interest. NOTE 2 The certainty of identification is affected by the types and/or number of characteristics investigated. 3.10 micro-environment defined location in the environment potentially occupied by an organism NOTE This “micro-environment” can impart a degree of confinement on th

35、e dispersal of the organism. 3.11 monitoring regular or continuous observation or collection of data with respect to an organism, process or procedure NOTE In this standard, monitoring applies to the progress of a released genetically modified organism. 3.12 monitoring protocol list of sequential st

36、eps and methods to be used for monitoring 3.13 monitoring strategy procedure for designing, reviewing, executing and documenting a monitoring protocol 3.14 phenotype sum of the traits of an organism NOTE 1 The phenotype can be described with respect to one or more traits under a given set of conditi

37、ons. NOTE 2 In the case of a virus, the phenotype can be described by one or more traits manifested in the infected host. 3.15 release site defined area which contains one or more experimental fields NOTE Several different trials can occur within a release site. 4 General considerations Monitoring i

38、s important in order to test predictions made with respect to the behaviour of the GMM in a release site. The availability and use of adequate controls is essential for the validity of the results. The design and execution of a monitoring valid strategy is therefore dependent on the particular objec

39、tives of the monitoring strategy. These can include the following. a) Studies on the functioning of the genetic modification in the GMM, released in the environment. The monitoring programme can include studies on the molecular stability and functional expression of the gene(s) involved in the genet

40、ic modification of interest. b) Studies on the effect of the genetic modification of interest on the behaviour of the GMM, released in the environment. The monitoring strategy can include studies on the presence of the GMM of interest or its hosts in environmental samples or its performance in the e

41、nvironment including effects on the ecosystem considered. c) Studies on the transfer of the gene(s) involved in the genetic modification of interest. The monitoring programme can include studies on transfer to the indigenous microbial population. 5 Monitoring strategy 5.1 General It is first necessa

42、ry to determine the objectives of the monitoring strategy. The main steps in the development of the monitoring strategy are: a) design and review of the monitoring protocol; b) validation of the monitoring protocol; c) execution of the monitoring protocol; d) record keeping. Responsibility for these

43、 steps should be assigned to a specific authority, organization or person. The monitoring strategy should be reviewed regularly, in the light of the inspections of the release site, to ensure its continuing validity. 5.2 Criteria for the design of the monitoring protocol The following key factors sh

44、ould be considered in the initial design of the protocol to ensure the design correlates with the monitoring strategy objectives as determined by the person designing the test: a) sampling strategy appropriate to the objectives and needs of the monitoring strategy as described in EN 12686; NOTE The

45、development of a monitoring and sampling valid strategy for deliberate releases of genetically modified micro-organisms in the environment is summarized in Figure A.1. b) extent of monitoring necessary to fulfil the requirements of the experiment such as timescale, scale and area of sampling; c) pre

46、dicted behaviour of GMM, particularly with respect to competitive ability, dispersal, persistence and the ability to form spores, resting forms and other specialized structures; d) relevant area for monitoring in line with the monitoring objectives such as the release site and/or the potential dispe

47、rsal area; e) particular features of the release site to monitor such as adjacent sites, streams, soil movement activities, meteorological parameters, soil properties; f) presence of potential hosts, presence of potential microbial vectors; g) appropriate choice of monitoring methods.Page 5 EN 12685

The following lists of factors and criteria should not be con
