Quality of air pollution measurements in the EU monitoring networks
The European Reference Laboratory of Air Pollution (ERLAP) has carried out quality assurance programmes for the monitoring of sulphur dioxide, black smoke, nitrogen dioxide and is currently organizing a similar programme for PM10 and ozone. On the basis of the information collected during these programmes, it has been possible to classify the European Union (EU) monitoring networks in different categories, in terms of implemented quality systems and data quality levels. A quantitative evaluation of the data quality, expressed as maximal uncertainty of the measurements associated with each quality level, was derived from experimental data. The advantage of implementing a standardized quality system is shown to result in a net improvement of the measurement quality. The accreditation of air pollution laboratories according to International Standardisation Organisation (ISO) 9000 or EN 45000 is therefore the only enforceable way to guarantee effectively the quality of air pollution measurements.
