15、 (E) 3 Foreword This document (EN 15980:2011) has been prepared by Technical Committee CEN/TC 264 “Air quality”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the late
16、st by November 2011, and conflicting national standards shall be withdrawn at the latest by November 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all
17、 such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hung

BS EN 15980:2011EN 15980:2011 (E) 4 Introduction Directive 2004/107/EC 2 requires the measurement of the “total o
19、r bulk deposition“ of benzaanthracene (BaA), benzobfluoranthene (BbF), benzojfluoranthene (BjF), benzokfluoranthene (BkF), benzoapyrene (BaP), dibenza,hanthracene (DBahA) and indeno1,2,3-cdpyrene (INP) at background sites, one every 100 000 km. Wet-only sampling may be used instead of bulk sampling
20、if it can be shown that the difference between their results is within 10 %. Where appropriate, monitoring shall be coordinated with the European Monitoring and Evaluation Programme (EMEP). The Directive uses “total deposition“ and “bulk deposition“ as synonyms and defines it as the total mass of po
21、llutants which is transferred from the atmosphere to surfaces (e.g. soil, vegetation, water, buildings) in a given area within a given time. The considered polycyclic aromatic hydrocarbons (PAH) are predominantly bound to particles. The mass of PAH bound to non sedimenting particles is thought to be
22、 low compared to the mass of the compounds bound to sedimenting wet and dry particles. Consequently the sum of the deposition of sedimenting wet and dry particles (defined as “bulk deposition“ in this European Standard) and total deposition has been considered as substantially equivalent for the pur
23、poses of this document. At sites far enough from obstacles like buildings and trees the influence of specific surface characteristics on the deposition of PAH can be neglected. This document describes the measurement of the deposition of PAH using collectors designed for bulk and wet-only deposition
24、. The validation field test demonstrated that the funnel-bottle bulk collector provided the most reliable and robust results. Therefore this collector type has been chosen as standard collector. BS EN 15980:2011EN 15980:2011 (E) 5 1 Scope This document specifies a method for the determination of the
25、 bulk deposition of benzaanthracene (BaA), benzobfluoranthene (BbF), benzojfluoranthene (BjF), benzokfluoranthene (BkF), benzoapyrene (BaP), dibenza,hanthracene (DBahA) and indeno1,2,3-cdpyrene (INP), which can be used in the framework of Directive 2004/107/EC. This European Standard specifies perfo
26、rmance requirements with which the method has to comply in order to meet the data quality objectives given in this Directive. This document specifies methods for sampling, sample preparation and analysis using gas chromatography with mass spectroscopic detection (GC/MS) or high performance liquid ch
27、romatography with fluorescence detection (HPLC/FLD). The funnel-bottle bulk collector is used as the standard collector. The method is applicable for deposition measurements in rural and remote areas, industrial areas, urban areas. The standard is applicable in the range from a few ng/(m2d) to a few
28、 hundred ng/(m2d). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
