19、645:2014CEN/TS 16645:2014 (E) 4 Foreword This document (CEN/TS 16645:2014) has been prepared by Technical Committee CEN/TC 264 “Air quality”, the secretariat of which is held by DIN. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

20、 CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia,

21、 Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the U

22、nited Kingdom. PD CEN/TS 16645:2014CEN/TS 16645:2014 (E) 5 Introduction The measurement methods specified in this document are based on methods that were worked out during the laboratory and field validation tests for the European Standards EN 15549 5 (determination of BaP in ambient air) and EN 159

23、80 6 (determination of the deposition of several particle bound PAH compounds). Many data on the performance of the extraction and analysis of benzaanthracene (BaA), benzobfluoranthene (BbF), benzojfluoranthene (BjF), benzokfluoranthene (BkF), dibenza,hanthracene (DBahA), indeno1,2,3-cdpyrene (INP)

24、and benzoghiperylene (BghiP) in deposition or PM10 samples were gathered. These data do not cover the complete measurement procedure including sampling and consequently enable publication of a Technical Specification instead of a European Standard. It is the long-term goal to combine this document w

25、ith EN 15549 5, once adequate progress has been made in the development of reliably working oxidant denuders. PD CEN/TS 16645:2014CEN/TS 16645:2014 (E) 6 1 Scope This Technical Specification specifies a measurement method for the determination of the particle bound polycyclic aromatic hydrocarbon (P

26、AH) compounds benzaanthracene (BaA), benzobfluoranthene (BbF), benzojfluoranthene (BjF), benzokfluoranthene (BkF), dibenza,hanthracene (DBahA), indeno1,2,3-cdpyrene (INP) and benzoghiperylene (BghiP) in ambient air, which can be used in the framework of Council Directive 2008/50/EC 10 and Directive

27、2004/107/EC 11. This document specifies performance characteristics and performance criteria for this measurement method. The performance characteristics of the measurement method are based on a sampling period of 24 h. This Technical Specification describes a measurement method which comprises samp

28、ling of the selected PAH compounds as part of the PM10 particles, sample extraction and analysis by high performance liquid chromatography (HPLC) with fluorescence detector (FLD) or by gas chromatography with mass spectrometric detection (GC-MS). The method is applicable for the measurement of the P

29、AH compounds in the concentration range from approx. 0,04 ng/m3to approximately 20 ng/m3for BaA, BbF, BjF, BkF, BaP, INP and BghiP and 0,02 ng/m3to approximately 2 ng/m3for DBahA.
