Investigation of trace element atmospheric pollution by nuclear analytical techniques at a global scale: Harmonised approaches supported by the IAEA

In the framework of the IAEA programmes, Member States involved in air pollution studies using nuclear analytical techniques have harmonised their methodologies. Participants characterising chemical composition of size fractionated airborne particulate matter based their methodology on a common type of air sampler, centralised data collection and evaluation, and the same kind of data processing. Institutions involved in biomonitoring air pollution identified appropriate organisms to be applied at a regional scale, and harmonised procedures for sample preparation and analysis, as well as data processing and presentation. Both metrology approaches have been validated and disseminated in many Member States.
