Messdaten Gamma-ODL: Station Baar (Schwaben)

Das ODL-Messnetz des BfS überwacht mit rund 1.700 Messsonden rund um die Uhr die Strahlenbelastung durch natürliche Radioaktivität in der Umwelt. Das Messnetz hat eine wichtige Frühwarnfunktion, um erhöhte Strahlung durch radioaktive Stoffe in der Luft in Deutschland schnell zu erkennen. * [Informationen und Karte mit allen Messstationen](https://odlinfo.bfs.de/ODL/DE/themen/wo-stehen-die-sonden/karte/karte_node.html) * [Wichtige Hinweise zu den Daten - PDF](https://odlinfo.bfs.de/SharedDocs/Downloads/ODL/DE/datenbereitstellung.pdf?__blob=publicationFile&v=4)

Biogeochemical Processes in Tropical Soils

In recent years science has taken an increased interest in mineralization processes in tropical soils in particular under minimal tillage operations. Plant litter quality and management strongly affect mineralization-nitrification processes in soil and hence the fate of nitrogen in ecosystems and the environment. Plant secondary metabolites like lignin and polyphenols are poorly degradable and interact with proteins (protein binding capacity) and hence protect them from microbial attack. Nitrification, a microbiological process, directly and indirectly influences the efficiency of recovery of N in the vegetation as well as the loss of N (through denitrification and leaching) causing environmental pollution to water bodies and contributes to global warming (e.g. the greenhouse gas N2O is emitted as a by-product of nitrification and denitrification). Nitrifiers comprise a relatively narrow species diversity (at least as known to date) and are generally thought to be sensitive to low soil pH and stress. Despite these properties nitrification occurs in acid tropical soils with high levels of aluminium and manganese. Thus the main objective of the project will be the identification of micro-organisms and mechanisms responsible for mineralization-nitrification processes in acid tropical soils and the influence of long-term litter input of different chemical qualities and minimal tillage options. The project will include the use of stable isotopes (15N, 13C), mass spectrometry, gas chromatography (CO2, N2O), biochemical methods (PLFA) and molecular biology (16s rRNA., PCR, DGGE)

Narkosegas-Belastung in der Raumluft: Einfluss von Narkose-Verfahren und lueftungstechnische Aspekte

Ziel des Forschungsvorhabens ist, die Narkosegas-Belastung fuer Krankenhaus-Personal so gering wie moeglich zu halten. Hierzu wurde die Narkosegas-Belastung an verschiedenen Arbeitsplaetzen im Uniklinikum Tuebingen systematisch erfasst und im Kontext zu verschiedenen Narkose-Verfahren und oertlichen Gegebenheiten bewertet. Ergebnisse bisher: 1) Der Einsatz von Larynxmasken und ungeblockten Endotracheal-Tuben in der Kinder-Anaesthesie fuehrt zu vergleichbarer Narkosegas-Belastung fuer das Personal. In vollklimatisierten OP-Raeumen (Luftwechselzahl 16) koennen bei beiden Narkoseverfahren die vorgeschriebenen Grenzwerte deutlich unterschritten werden. 2) Nachtraeglich eingebaute Lueftungs-Anlagen in Aufwachraeumen koennen zur Reduktion der Narkosegas-Belastung beitragen, auch wenn sie faelschlicherweise unter der Decke und nicht am Boden installiert wurden. 3) Bei voll klimatisierten OP-Raeumen laesst sich Isofluran im Blut von Anaesthesisten nur wenige Minuten nach Masken-Einleitung von Kindern nachweisen. 15 Minuten nach Einleitung ist Isofluran im Blut unter der Nachweisgrenze (1 ng/ml).

Establishment of Teak plantations for high-value timber production in Ghana

Background and Objectives: The project area is located in the Ashanti Region of Ghana / West Africa in the transition zone of the moist semideciduous forest and tropical savannah zone. Main land use in this region is subsistence agriculture with large fallow areas. As an alternative land-use, forest plantations are under development by the Ghanaian wood processing company DuPaul Wood Treatment Ltd. Labourers from the surrounding villages are employed as permanent or casual plantation workers. Within three forest plantation projects of approximately 6,000 ha, DuPaul offers an area of 164 ha (referred to as Papasi Plantation) - which is mainly planted with Teak (Tectona grandis) - for research purposes. In return, the company expects consultations to improve the management for sustainable timber and pole production with exotic and native tree species. Results: In a first research approach, the Papasi Plantation was assessed in terms of vegetation classification, timber resources (in qualitative and quantitative terms) and soil and site conditions. A permanent sampling plot system was established to enable long-term monitoring of stand dynamics including observation of stand response to silvicultural treatments. Site conditions are ideally suited for Teak and some stands show exceptionally good growth performances. However, poor weed management and a lack of fire control and silvicultural management led to high mortality and poor growth performance of some stands, resulting in relative low overall growth averages. In a second step, a social baseline study was carried out in the surrounding villages and identified landowner conflicts between some villagers and DuPaul, which could be one reason for the fire damages. However, the study also revealed a general interest for collaboration in agroforestry on DuPaul land on both sides. Thirdly, a silvicultural management concept was elaborated and an improved integration of the rural population into DuPaul's forest plantation projects is already initiated. If landowner conflicts can be solved, the development of forest plantations can contribute significantly to the economic income of rural households while environmental benefits provide long-term opportunities for sustainable development of the region.

Waterbase - UWWTD: Urban Waste Water Treatment Directive – reported data

The Urban Waste Water Treatment Directive concerns the collection, treatment and discharge of urban waste water and the treatment and discharge of waste water from certain industrial sectors. The objective of the Directive is to protect the environment from the adverse effects of the above mentioned waste water discharges. This series contains time series of spatial and tabular data covering Agglomerations, Discharge Points, and Treatment Plants.

NECPR: Additional Reporting Obligations in the area of Renewable Energy (Annex XVI) dataset, 2023

Additional reporting in the area of renewable energy is a dataset under the National Energy and Climate Progress Reports (NECPRs), which is reported every second year (starting in 2023) by EU Member States. The dataset provides information regarding Member States functioning system for guarantees of origin (GO), renewable energy surplus/deficits, biomass use and impacts, and renewable energy usage in buildings. The EEA collects and quality checks this data. The dataset links to data from Eurostat. This reporting obligation comes from the Governance Regulation 2018/1999, Implementing Regulation (EU) 2022/2299 (Annex XVI).

Saisonale Kaeltespeicherung im Erdreich

Zielsetzung: Bereits 1987 wurde in einem Firmengebaeude in Wetzlar erstmals der Erdsondenteil einer erdgekoppelten Waermepumpe als Kaeltespeicher benutzt und direkt zur Kuehlung eines Konferenzraumes im Sommer herangezogen. Nunmehr sollen durch weitere Untersuchungen die Einsatzfaehigkeit und Auslegungskriterien fuer derartige energiesparende Raumkuehlungsanlagen festgestellt werden. Arbeiten und bisherige Ergebnisse: In zwei Gebaeuden (Technorama, Duesseldorf, und Betriebsgebaeude Geotherm, Linden) wird eine Raumkuehlung mit Kaeltespeicherung im Erdreich betrieben. Dabei ist in Linden nur die direkte Kaelterueckgewinnung vorgesehen, waehrend in Duesseldorf zur Deckung des Spitzenbedarfs reversible Waermepumpen zugeschaltet werden koennen. Beide Anlagen haben im Sommer 1991 voll zufriedenstellend gearbeitet. Studien fuer den Einsatz in anderen Gebaeuden liegen vor; fuer die Auslegungsrechnung wurden PC-Programme der Universitaet Lund, Schweden, eingesetzt. In einem eigenen Projekt wurde ein Bericht zum Stand der Technik erstellt.
