Comprehensive Study on PM Mass Closure in Germany and its Impact on Air Quality Assessments

This workshop report presents findings from mass closure studies on particulate matter (PM) in Germany, focusing on sources and composition, with contributions from various regions. The report highlights the influence of site type on PM composition and the impact on air quality assessments. It also discusses the results of source apportionment studies and provides an outlook on the German contribution to this research.
