Die Stickstoffflächenbilanzierung auf landwirtschaftlichen Flächen auf Ebene der Kreise nach Häußermann und Bach ist ein zentraler Baustein der Quantifizierung von Stickstoffflüssen in Deutschland. Insbesondere aufgrund der anhaltenden Überlastung zahlreicher Wasserkörper mit Nitrat stellt das Flächenbilanzierungsmodell ein essentielles Bewertungsinstrument zur Politikberatung und wissenschaftlichen Fundierung der Rechtssetzung und Maßnahmenplanung dar. Der Bericht dokumentiert die Implementierung des Bilanzierungsmodells in eine zeitgemäße Architektur sowie dessen Überführung ans Umweltbundesamt.

Spatial resolution of exposure to particulate matter (PM2.5) and the impact on the burden of disease in Germany
(2026) Wallek, Stefan; Langner, Marcel; Plaß, Dietrich; Kienzler, Sarah; Sauter, Tobias
Accurate estimation of the disease burden attributable to ambient particulate matter (PM2.5) requires reliable exposure data with an adequate spatial resolution. While coarse-resolution models are commonly used for national assessments, the impact of spatial resolution on environmental burden of disease (EBD) estimates remains understudied. We compared two modelling approaches for PM2.5 exposure in Germany: a chemical transport model (REM-CALGRID [RCG], 2 × 2 km² resolution) and a high-resolution hybrid geostatistical land-use regression model (PMR, 100 × 100 m² resolution). EBD estimates were calculated for five health outcomes using established concentration-response functions. Across all outcomes, the PMR model consistently produced slightly higher EBD estimates—approximately 2%–3% higher disability-adjusted life years (DALYs) than the coarser RCG model. The difference is due to improved detection of local pollution hotspots and more accurate exposure assignments in the high-resolution model. A larger share of the population was classified into higher exposure categories under the PMR model. Although the added value of high-resolution modelling is limited at national level, it offers clear benefits for small-area analyses and applications in environmental justice and health equity. Our findings support the integration of fine-scale exposure data into public health surveillance and burden of disease (BoD) assessments where feasible. © The Author(s) 2026
Messen geringer Quecksilberkonzentrationen im Abgas von industriellen Prozessen zur Ermittlung neuer Verfahrenskenngrößen für das Standardreferenzverfahren nach EN 13211 (2001) sowie das Alternativverfahren nach CEN/TS 17286 (2019) (Sorbent Traps)

Aufgrund neuer herabgesetzter Emissionsgrenzwerte für Quecksilber sollten neue Verfahrenskenngrößen für das Referenzverfahren nach EN 13211 ermittelt werden. Zusätzlich sollte auch die Eignung für die Überwachung niedriger Quecksilberkonzentrationen der Sorbent-Trap-Methode nach CEN/TS 17286 untersucht werden.Im Bericht werden die Ergebnisse aus den Validierungsmessungen, die durch drei nach §29 b BImSchG bekanntgegebene Messstellen an verschiedenen industriellen Anlagen durchgeführt wurden, dargestellt. Die Ergebnisse sollen insbesondere in der Normungsarbeit Verwendung finden.
German Informative Inventory Report 2026

The Informative Inventory Report (IIR) is providing complementary information to Germany's air pollution inventories under the Geneva Convention on Long-range Transboundary Air Pollution of the United Nations Economic Commission for Europe (UNECE/CLRTAP) as well as the EU's National Emission Ceiling Directive (NECD).
Germany's air pollution inventory includes emission data in consistent time-series ranging from 1990 (1995 for PM10
, PM2.5 and 2000 for Black Carbon) to the latest reported year for all 26 air pollutants or groups of air pollutants (NOx
, NMVOC, PCDD/PCDF) considered under UNECE reporting.
This report provides a comprehensive analysis of the inventory data, descriptions of the methods applied, data sources, and carried out QA/QC procedures. It follows the outline established by the latest guidelines for estimating and reporting of emission data and all data presented in this report were compiled according to those same guidelines.
However, this report does not provide a comprehensive discussion on air pollution or the measures and politics dealing with it. Such information is included in the published national programs for further emission reductions, e.g. under the NEC directive or the trend and projection reports for green-house gases. Instead, it provides a detailed insight on the process of air pollution and emission inventory preparation. The focus lies on the methods and assumptions used for the German emission reporting and to underpin the “technical” review of the emission data as reported under the CLRTAP convention
and its protocol.
