This Technical Specification specifies a measurement method for the determination of the particle bound polycyclic aromatic hydrocarbon (PAH) compounds benz[a]anthracene (BaA), benzo[b]fluoranthene (BbF), benzo[j]fluoranthene (BjF), benzo[k]fluoranthene (BkF), dibenz[a,h]anthracene (DBahA), indeno[1,2,3-cd]pyrene (INP) and benzo[ghi]perylene (BghiP) in ambient air, which can be used in the framework of Council Directive 2008/50/EC and Directive 2004/107/EC. 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 sampling 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 PAH compounds in the concentration range from approx. 0,04 ng/m 3 to approximately 20 ng/m 3 for BaA, BbF, BjF, BkF, BaP, INP and BghiP and 0,02 ng/m 3 to approximately 2 ng/m 3 for DBahA. Table 1 shows examples for concentrations of the compounds (annual mean values) for sampling sites with different characteristics. The lower limit of the applicable range depends on the noise level of the detector and the variability of the laboratory filter blank.
Ambient air - Method for the measurement of benz[a]anthracene@ benzo[b]fluoranthene@ benzo[j]fluoranthene@ benzo[k]fluoranthene@ dibenz[a@h]anthracene@ indeno[1@2@3- cd]pyrene and benzo[ghi]perylene
This Technical Specification specifies a method for the determination of benzo[a]pyrene (BaP) plus benz[a]anthracene (BaA), benzo[b]fluoranthene (BbF) and chrysene (CHR) in several food matrices. The method is based on size exclusion chromatography (SEC) cleanup, followed by quantification with high performance liquid chromatography (HPLC) with programmable fluorescence detection. This method has been in-house validated via the analysis of spiked samples of edible olive oil, fresh mussels, smoked fish, smoked meat products, processed cereal-based foods for young children, infant formulae, chocolate and food supplements (isoflavones) at levels ranging from 0,25 g/kg to 1,00 g/kg and from 4,95 g/kg to 23,53 µg/kg, depending on the Polycyclic Aromatic Hydrocarbon (PAH) or the matrix. This method complies with the performance characteristics specified for BaP, BaA, BbF and CHR in current legislation. The method has been shown to be applicable to a variety of additional matrices as meat products, fresh fish, paprika, roasted coffee, bread, herbs, breakfast cereals, beer, sunflower oil, olives and fried tomato, with a limit of quantification below 0,5 µg/kg. In addition, the method was tested in-house and shown to be applicable also for the quantification of the other 12 PAHs of the 15+1 EU priority PAHs set (benzo[c]fluorene (BcL), benzo[j]fluoranthene (BjF), benzo[k]fluoranthene (BkF), cyclopenta[cd]pyrene (CPP), dibenz[a,h]anthracene (DhA), dibenzo[a,e]pyrene (DeP), benzo[ghi]perylene (BgP), dibenzo[a,h]pyrene (DhP), dibenzo[a,i]pyrene (DiP), dibenzo[a,l]pyrene (DlP), indeno[1,2,3-cd]pyrene (IcP), 5-methylchrysene (5MC)) in all matrices listed above and at similar level ranges, except for CPP, where a UV detection had to be used with limits of quantification above 8 µg/kg. For the determination of PAHs in edible fats and oils, two other standards are also available, EN ISO 22959 and EN ISO 15753.
