Air quality - Standard method for the measurement of the concentration of benzo[a]pyrene in ambient air

This document specifies a measurement method for the determination of particulate benzo[a]pyrene (BaP) in ambient air, which can be used in the framework of the Council Directive 96/62/EC [1] and the Directive 2004/107/EC [2]. This document specifies performance characteristics and performance criteria to which the method should comply when it is used as a reference method. The performance characteristics of the measurement method are based on a sampling period of 24 h.
This document describes a measurement method which comprises sampling of BaP 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 BaP in the concentration range from approx. 0,04 ng/m3 to approximately 20 ng/m3.
The lower limit of the applicable range depends on the noise level of the detector and the variability of the laboratory filter blank.
NOTE   If the BaP concentration exceeds the calibration range the extract can be diluted.

Luftbeschaffenheit - Messverfahren zur Bestimmung der Konzentration von Benzo[a]pyren in Luft

Dieses Dokument legt ein Messverfahren zur Bestimmung von partikelgebundenem Benzo[a]pyren (BaP) in Luft fest, das im Zusammenhang mit der Richtlinie 96/62/EG [1] und der Richtlinie 2004/107/EG [2] ange¬wendet werden kann. Dieses Dokument legt Verfahrenskenngrößen und Leistungskriterien für das Mess¬verfahren fest, wenn es als Referenzverfahren eingesetzt wird. Die Verfahrenskenngrößen beruhen auf einer Probenahmedauer von 24 h.
Dieses Dokument beschreibt ein Messverfahren, das die Probenahme von BaP als Bestandteil der PM10-Partikel, die Probenextraktion und die Analyse mit Hochleistungs-Flüssigkeitschromatographie (HPLC) in Kombination mit einem Fluoreszenzdetektor (FLD) oder mit Gaschromatographie in Kombination mit massen¬spektro¬metrischer Detektion (GC/MS) umfasst. Das Verfahren ist anwendbar für die Messung von BaP im Konzentrationsbereich von etwa 0,04 ng/m3 bis etwa 20 ng/m3.
Die untere Grenze des Anwendungsbereichs hängt vom Rauschpegel des Detektors und der Streubreite des Laborfilterblindwerts ab.
ANMERKUNG   Falls die BaP-Konzentration den Kalibrierbereich übersteigt, kann der Extrakt verdünnt werden.

Qualité de l'air - Méthode normalisée pour le mesurage de la concentration de benzo[a]pyrène dans l'air ambiant

Le présent document spécifie une méthode de mesure permettant de déterminer la concentration de benzo[a]pyrène (BaP) particulaire dans l’air ambiant, qui peut être utilisée dans le cadre de la Directive 96/62/CE du Conseil [1] et de la Directive 2004/107/CE [2]. Le présent document spécifie des caractéristiques de performance et des critères de performance pour la méthode de mesure lorsque celle-ci est utilisée comme une méthode de référence. Les caractéristiques de performance de la méthode de mesure sont basées sur une période de prélèvement de 24 h.
Le présent document décrit une méthode de mesure comprenant l’échantillonnage du BaP faisant partie intégrante des particules PM10, l’extraction et l’analyse d’échantillons par chromatographie liquide à haute performance (CLHP) avec un détecteur de fluorescence (FLD) ou par chromatographie en phase gazeuse avec détection par spectrométrie de masse (CG/SM). La méthode est applicable au mesurage du BaP dans la plage de concentration comprise approximativement entre 0,04 ng/m3 et 20 ng/m3.
La limite inférieure de la plage applicable dépend du niveau de bruit de fond du détecteur et de la variabilité de la valeur des blancs des filtres de laboratoire.
NOTE   Si la concentration de BaP dépasse la plage d’étalonnage, l’extrait peut être dilué.

Foreword
This document (EN 15549:2008) 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 latest by September 2008, and conflicting national standards shall be

rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
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, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Sweden, Switzerland and the United Kingdom.
Introduction
The European Directive 2004/107/EC prescribes the reference methodology for the measurement of
benzo[a]pyrene (BaP) in ambient air and states that the method shall be a method based on manual PM10
sampling systems described in EN 12341 or equivalent.
Hence, this European Standard describes a method in which the sampling systems fulfil this requirement.
However, in the course of drafting this European Standard it became clear that in certain circumstances, in the
presence of oxidants such as ozone, BaP may be degraded. In specific situations this may result in losses of
BaP of > 50 %. It has been shown that the degradation due to ozone can be substantially reduced by
including an ozone denuder in the sampling system.
To date only a limited number of experiments has been performed in order to evaluate the particular
conditions under which the denuder systems can be efficiently used. Consequently, the application of ozone
denuders lacks sufficient validation to be a normative part of this European Standard.
In order to have a complete picture of the performance of ozone denuder systems further information is
required on:
• efficiency under variable atmospheric conditions,
• regeneration time after exposure to high humidity,
• maximum capacity for ozone,
• maximum sample volume and maximum sampling period,
• stability of catalyst,
• maximum period of use,
• particle losses.
Examples of sampling using an ozone denuder are given in Annex A.
The experimental evidence collected so far is presented in Annex F.
It is recommended that further work is undertaken to provide data of BaP comparisons with and without ozone
denuders.
