Data collection coordination is supplied by the exchange of information. Methodologies, Quality Control, Harmonization Quality is assured by regular intercalibration exercises, as well as harmonized sampling, analysis, and evaluation of water chemistry and biota. The publication of annual data and technical reports is used to disseminate the information to Governments, experts and the general public in the ECE region. The activities are coordinated within the EB activities. See check list in annex .
Data collection is coordinated via exchange of information.
Methodologies, Quality Control, Harmonization Quality control is assured by comparison of results of analysis and the use of specialized laboratories for individual investigated materials. There is a standard methodology for exposure and evaluation of specimens. The experiment format is evaluation of corrosion of important materials, exposed to effect of air pollution at a number of test sites. Publication is coordinated within the EB activities, as well as the exchange of Technical information with other organizations. Data gaps require more complete data on air pollution at test sites and a more balanced geographical distribution of test sites.
