Call for 4th Proficiency Testing Scheme (PTS) for PM10 and PM2.5 mass concentration measurements

Dear ACTRIS partners,

Particulate Matter (PM) is considered as one of the most harmful air pollutant in outdoor air for human health. Although PM mass concentrations (PM10 and PM2.5) are not ACTRIS variables, they can be useful in data QC processes like e.g. mass closure exercises.

In January – February 2025, the European Reference Laboratory for Air Pollution of the EC – Joint Research Centre will organise its 4th Proficiency Testing Scheme (PTS) for PM10 and PM2.5 mass concentration measurements. Practically, the results obtained by the participants during a 6-week field campaign in Ispra (IT) will be statistically evaluated according to relevant ISO guides. Participants shall primarily use the reference method described in the European standard EN 12341. However, on-line instruments will be accommodated as much as possible.

Participation in this PTS is free of charge for public Research Performing Organisations. Transport and accommodation will be at your own cost and no certificate will be issued.

You may express your interest in participating through the web platform JRC-ERLAP PT-DAP following the link: https://erlap-intercomparison.jrc.ec.europa.eu

Your application will be evaluated at the closure of the registration period on 15 October 2024.

The protocol of this PTS and instructions about data submission are available at the PT-DAP platform.

All official communication is managed through a functional mailbox at JRC: JRC-ERLAP@ec.europa.eu

Looking forward to reading your expression of interest and having a fruitful cooperation,

Jean-Philippe Putaud
