PD CEN/TS 16817-1:2015CEN/TS 16817-1:2015 (E) 6 Introduction The European Parliament and the European Council require an environmental risk assessment and a post-marketing monitoring for any GMO released to the environment 5; 6. This had to be implied in national law in

30、 any member state of the EC by date. Pollen dispersal plays a significant role in the dissemination of genetically modified organisms (GMO). A procedure is described for GMO monitoring that enables quantification and documentation of GMO input and spread through pollen in a nationwide monitoring net

31、work which represents natural landscapes. Technical and biological pollen sampling (the present Technical Specification and CEN/TS 16817-2) and molecular biological analysis methods (polymerase chain reaction (PCR) for DNA; Enzyme-linked immunosorbent assay (ELISA) for proteins) are used for the det

32、ection of GMO input. It is reasonable to use both technical and biological sampling of pollen, thus they supplement each other in manifold ways. The technical sampling (i.e. the present document) is conducted with stationary point-samplers. They give a record of pollen input at the sample site that

33、correlates with the prevailing wind direction and relative position to the surrounding pollen sources. Bee colonies actively roam an area and are therefore area related samplers. Further, pollen sampling depends here on the collection activity of the bees and the availability of pollen sources withi

34、n the roaming area according to the bees preferences and supply of melliferous plants 32. Presently known pollen traps are only partially suited for GMO monitoring, since they can neither be standardized nor is the instrumentation designed for exposure times that are suitable for this purpose. Anoth

35、er limitation of commonly used pollen samplers is the requirement for a power supply, e.g. as for the Hirst type trap. The use of these instruments is therefore restricted to a limited exposure area. For these reasons, a new type of passive pollen sampler, the pollen mass filter (PMF), was developed

36、. The PMF is used either in combination with the Sigma-2 passive sampler or solely. The present Technical Specification is largely based on German VDI/Guideline 4330 Part 3 31. PD CEN/TS 16817-1:2015CEN/TS 16817-1:2015 (E) 7 1 Scope This Technical Specification describes a procedure for the use of t

37、he passive samplers Sigma-2 and PMF to sample airborne pollen. Both are designed to sample coarse aerosol particles. Collected samples are used to analyse pollen input with regard to pollen type and amount, and input of transgenic pollen. The Sigma-2 passive sampler here provides a standardized samp

38、ling method for direct microscopic pollen analysis and quantifying the input of airborne pollen at the site. The PMF yields sufficient amounts of pollen to additionally carry out molecular-biological diagnostics for detection of GMO. Essential background information on performing GMO monitoring is g

39、iven in VDI/Guideline 4330 Part 1 4, which is based on an integrated assessment of temporal and spatial variation of GMO cultivation (sources of GMO), the exposure in the environment and biological/ecological effects. Ideally, the pollen sampling using technical samplers for GMO monitoring should be

40、 undertaken in combination with the biological collection of pollen by bees (CEN/TS 16817-2). The application of technical passive samplers and the use of honey bee colonies as active biological collectors complement each other in a manifold way when monitoring the exposure to GMO pollen. Technical

41、samplers provide results regarding the pollen input at the sampling site in a representative way, whereas with biological sampling by honey bee colonies, pollen from flowering plants in the area is collected according to the bees collection activity. Thus, this method represents GMO exposure to roam

42、ing insects. By combining the two sampling methods these two main principles of exposure are represented. Furthermore, a broad range of pollen species is covered. The sample design depends on the intended sampling objective. Some examples are given in 6.2. 2 Normative references The following docume
