Reference method for the sampling and measurement of polycyclic aromatic hydrocarbons in ambient air The reference method for the sampling of polycyclic aromatic hydrocarbons in ambient air is that described in EN 12341:2023 ‘Ambient Air – Standard gravimetric measurement method for the determination of the PM10 or PM2,5 mass concentration of suspended particulate matter’. The reference method for the measurement of benzo(a)pyrene in ambient air is that described in EN 15549:2008 ‘Air quality – Standard method for the measurement of concentration of benzo[a]pyrene in ambient air’. In the absence of an EN standard method for the other polycyclic aromatic hydrocarbons referred to in Article 9(8), Member States are allowed to use national standard methods or ISO methods such as ISO standard 12884.
