| Reference method | |
|---|---|
| Sampling and measurement of benzene | EN 14662:2005, Parts 1, 2 and 3 “Ambient air quality – standard method for measurement of benzene concentrations”(1) |
| Analysis of carbon monoxide | EN 14626:2005 “Ambient air quality – Standard method for the measurement of the concentration of carbon monoxide by nondispersive infrared spectroscopy” |
| Sampling of lead | The same reference method as for PM10 |
| Analysis of lead | ISO 9855: 1993 Ambient air – Determination of the particulate lead content of aerosols collected in filters. Atomic absorption spectroscopy method |
| Analysis of nitrogen dioxide and oxides of nitrogen | ISO 7996: 1985 Ambient air – determination of the mass concentrations of nitrogen oxides – chemiluminescence method |
| Sampling and measurement of PM10 | EN 12341:1998 “Air Quality – Field Test Procedure to Demonstrate Reference Equivalence of Sampling Methods for the PM10 fraction of particulate matter”. The measurement principle is based on the collection on a filter of the PM10 fraction of ambient particulate matter and the gravimetric mass determination |
| Analysis of sulphur dioxide | ISO/FDIS 10498 (Standard in draft) Ambient air – determination of sulphur dioxide – ultraviolet fluorescence method |
