New Practical Guidance on the use of Diffusion Tubes for Ambient NO2 Monitoring has now been released. The document presents the findings of the Working Group on harmonisation of NO2 diffusion tube preparation and analysis methods, led by AEA Energy & Environment and Air Quality Consultants on behalf of Defra and the Devolved Administrations. The guidance is primarily written for laboratories that supply and analyse diffusion tubes, but also contains useful guidance for diffusion tube users. The recommendations are expected to be implemented by all parties by January 1st 2009.
