REIN-project: Air quality data from gas and particle sensors at the river Rhine in Koblenz, Germany

This dataset provides data from various air quality sensors at a floating platform of the Federal Institute of Hydrology at the river bank of the Rhine in Koblenz, Germany. The data was collected as part of the mFUND project "REIN" which investigated the suitability of low-cost sensors for the determination of ship emissions with high spatial and temporal resolution. Measurement data involves various pollutants, including nitrogen oxides (NO, NO2), carbon dioxde (CO2) and particulate matter (particle number concentration, mass concentration, size distribution, ultrafine particles, black carbon concentration). Averaged data is provided at 1 minute and 1 hour temporal resolution and covers both low-cost and standard instruments. The dataset is related to the publication "Applicability of compact low- and mid-cost sensors to monitor air pollutant emissions from in-land ships".

Analytical data of a buried and a recent surficial Chernozem in the Bornhöck area in Central Germany

This dataset contains analytical data of two studied soil profiles, one of a buried (BH-II) and one of a recent surficial Chernozem (BH-rec) in the Bornhöck area in Central Germany (southern Saxony-Anhalt). At BH-II, the Chernozem was buried by the Early Bronze Age burial mound 'Bornhöck' about 3.8 ka. The study area is described in Suchodoletz et al. (2023). During our research we measured grain sizes, organic carbon and carbonate contents, black carbon, soil isotopes, elements and lignin phenols (S/V and C/V). The measurements were performed between 2019 and 2024. The goal of our study was to evaluate regional soil formation and human impact since the Early Bronze.

Klimakammer (Phytotron)

Die beantragte Klimakammer wird im Rahmen des vom MWFK Brandenburg seit 2009 geförderten Verbund-Forschungsvorhabens BIOBRA und zukünftiger Forschungsvorhaben eingesetzt. In BIOBRA arbeitet eine interdisziplinäre Forschergruppe von grundlagenorientierten Nachwuchswissenschaftlern/lnnen des MPI für Kolloid- und Grenzflächenforschung in Potsdam (Prof. Dr. M. Antonietti) und angewandten Wissenschaftlern/Innen der FH Eberswalde (Prof. Dr. Murach) zusammen. Durch die Verschneidung der innovativen Forschungsbereiche der hydrothermalen Karbonisierung (HTC-Forschung des Prof. Antonietti 2008 ausgezeichnet mit dem 'ERC Advanced Grant' der EU) und der Agrarholzproduktion (BMBF-Verbund-Forschungsvorhaben DENDROM des Prof. Murach 2007 in die BMBF-Hightechstrategie aufgenommen) soll der Einsatz der durch hydrothermale Karbonisierung aus Abfallstoffen gewonnenen 'Biokohle' zur Bodenverbesserung (Nährstoff- und Wasserspeicherung) degradierter Standorte und zur C-Sequestrierung am Beispiel der Agrarholzproduktion (Anbau schnellwachsender Baumarten im Kurzumtrieb) untersucht werden.Durch dieses Projekt wird die Agrarholzforschung der FH Eberswalde um einen experimentellen Ansatz erweitert, mit dem sie einen Beitrag zu den neuen, internationalen Forschungsschwerpunkten 'Biochar' / 'Black Carbon' / 'Terra Preta' leisten kann.Die Klimakammer soll Schnelltests zur Optimierung der verschiedenen Biokohlen als Bodenzusatzstoff für Pappel- und Weidenstecklingen unter standardisierten Umweltbedingungen ermöglichen.

Ermittlung von Black Carbon mit NUPS

Als Ergänzung zur den automatischen Messungen von Black Carbon (BC) durch das LÜSA werden an ausgewählten Messstandorten zusätzliche Messungen von Black Carbon mittels Netzunabhängiger Probenahmesysteme (NUPS) durchgeführt. BC bzw. Ruß entsteht bei unvollständiger Verbrennung von fossilen Energieträgern und Biomasse. Er ist ein verkehrstypischer Schadstoff für den kein Grenzwert festgelegt wurde. BC stellt gegenüber der Partikel PM 10 -Messung einen empfindlichen Indikator für den Nachweis der lufthygienischen Wirkung von verkehrsregelnden Maßnahmen dar. Die Messungen erfolgen an stark befahrenen Straßen oder Verkehrsknotenpunkten. Im Gegensatz zu den Messungen des LÜSA wird hiermit der BC im gesamten abgeschiedenen Staub bestimmt und nicht nur in der Partikel PM 2,5 -Fraktion. Standorte der BC-Messungen (2023) Ergebnisse der BC-Messungen (2018-2023) Ausführliche Messergebnisse und Auswertungen sind den jeweiligen Immissionsschutzberichten zu entnehmen.

Temperature-dependent changes in dissolved black carbon during heating of marine and terrestrial dissolved organic matter reference materials

Dissolved black carbon (DBC) is a condensed aromatic fraction of dissolved organic matter (DOM) and an important component of the marine carbon cycle. Hydrothermal systems have been suggested as a potential source of DBC to the deep ocean, but the mobilization and origin of DBC in organic-rich hydrothermal sediments remain poorly constrained. This dataset contains data from heating experiments performed to investigate the temperature-dependent mobilization of dissolved black carbon (DBC) from marine and terrestrial dissolved organic matter (DOM) reference materials under controlled aqueous heating conditions. The experiments were conducted with solid-phase extracted (SPE) marine DOM from North Equatorial Pacific Intermediate Water (NEqPIW), sampled and isolated at the Natural Energy Laboratory of Hawaii Authority (NELHA) as described by Green et al. (2014), and Suwannee River Natural Organic Matter (SRNOM), a terrestrial DOM reference material provided by the International Humic Substances Society (IHSS) and fisrt described by Serkiz & Perdue (1990). The reference materials were dissolved in ultrapure water and afterwards subjected to temperature treatments of 25, 80, 100, and 180 °C. DBC was determined using the benzene polycarboxylic acid (BPCA) method after Dittmar et al. (2008) and Wagner et al., (2017). BPCAs were quantified by ultra-performance liquid chromatography (UPLC), and DBC concentrations were calculated from benzene pentacarboxylic acid (B5CA) and benzene hexacarboxylic acid (B6CA) concentrations according to Stubbins et al. (2015). The dataset includes benzene tetracarboxylic acid (B4CA), B5CA, and B6CA concentrations, BPCA ratios, and calculated DBC concentrations for the different temperature treatments.

Particulate Matter emission reduction in international maritime shipping: Analysis and discussion of current status and outlook

Ships emit significant amounts of particulate matter (PM) in addition to other air pollutants such as nitrogen oxides (NOX) and sulfur oxides (SOX). The introduction of a Global Sulfur cap of 0.5% (m/m) in 2020 was supposed to reduce emissions of SOX and indirectly PM, but this has only been partially the case. For this reason, it may make sense to focus on reduction of PM mass and particle number (PN) emissions from international shipping next to the ongoing discussion in the International Maritime Organization on reducing black carbon (BC) in the Arctic. An overview of PM measurement methods and limits that have been established in PM related regulations in other transportation sectors is presented. Various ship-specific measures to reduce PM emissions are described, including the use of cleaner fuels, exhaust gas treatment systems and a combination of both. Based on the analysis of the status quo, possible measures for a regulatory framework are proposed.

Mobilisierung und Immobilisierung von Schadstoffen in Muellverbrennungsschlacken im realistischen Massstab

Wissenschaftliche Aufklaerung des kurz- und langfristigen Verhaltens von Schadstoffen bei der offenen Verwendung von Reststoffen mit dem Ziel, das Nutzungspotential zu quantifizieren. Dazu werden organische und anorganische Schadstoffe in Muellverbrennungsschlacken charakterisiert und spezifiziert, anhand geochemischer Modellrechnungen die thermodynamischen Existenzbereiche von Schwermetallspecies in Waessern ermittelt, die wesentlichen Mobilisierungsmechanismen untersucht und diese mit kapazitiven Groessen wie Saeure- und Redoxpufferkapazitaet gekoppelt. Bisher konnte an drei MVA-Schlacken durch TG- und DTA-Untersuchungen eine Speziation des Kohlenstoffs in organisch gebundenen, karbonatischen und graphitaehnlichen (black carbon) Kohlenstoff erreicht werden. Die Identifikation organischer Bestandteile gelang nach Soxhlet-Extraktion mit einer Reihe an Loesemitteln sinkender Polaritaet und dem Einsatz von GC-MS und HPLC-Technik. Damit konnten erstmals Alkane, Fettsaeuren, Phenole und Phthalate im mg/kg-Bereich in MVA-Schlacken nachgewiesen werden. Die Ionenchromatographie eignet sich nach Elimination von SO4 hoch 2minus, Cl minus fuer die Identifikation pelarer, org. Saeuren. Am Beispiel des Kupfers konnte fuer ein Schwermetall eine Speziation durchgefuehrt werden. Dabei wurden sechs Kupferphasen (Cu(O), Cu(l)-Oxid, Cu(II)-Oxid, Cu-Legierungen und basische Kupferkarbonate) identifiziert.
