Take EU biocides legislation to the next level

There is already more than a decade of experiences with environmental risk assessment under the Biocidal Products Regulation (EU) No 528/2012 (BPR). This paper compiles recommendations to improve BPR to ensure that it reaches its goals. Experiences have shown that the processes for environmental risk assessments need to be simplified to allow for faster decisions. Also, despite first BPR environmental benefits, some biocides still enter the environment significantly, and will continue to do so due to their intended uses. Therefore, our suggestions target these two categories: “streamlining environmental risk assessments” and “reducing biocide emissions to the environment”. Veröffentlicht in Scientific Opinion Paper.

Carbonate chemistry from laboratory incubation experiments using water samples from the Elbe conducted in 2023

This dataset comprises key carbonate chemistry parameters measured and calculated in incubation experiments under different experimental conditions. pH, water temperature, and salinity were measured with a WTW multimeter (MultiLine® Multi 3630 IDS). Total alkalinity was determined by open-cell titration with an 888 Titrando (Metrohm). Saturation state of calcite and aragonite were calculated using phreeqpython, a Python wrapper of the PhreeqC engine (Vitens 2021) with pH, water temperature, total alkalinity, and major ions as major input, and phreeqc.dat as database for the thermodynamic data (Parkhurst and Appelo 2013). As the original Elbe water was supersaturated with carbon dioxide (CO2) with respect to the atmosphere, its partial pressure of CO2 (pCO2) level decreased during the incubation period with open flasks, which caused an adjustment of calcite saturation state (ΩC) for ambient air conditions. To adapt for the impact of pCO2 variations during the experiment, saturation state of calcite and aragonite was calculated assuming an equilibrium with an atmospheric pCO2 of 415 ppm (normalized ΩC and normalized aragonite sautration state ΩA). Since ion concentrations were measured for only a small number of samples, the ion concentrations of the remaining samples were reconstructed using stoichiometry based on the initial solution composition and total alkalinity. The concentrations of conservative ions (Na+, K+, Cl-, SO42-) were assumed remain constant, while ions related to carbonate precipitation (Ca2+, Mg2+) were calculated based on changes in measured alkalinity (see Figure 5 of the associated paper). Detailed analysis and calculation procedures are described in the Method section of the associated paper.

Navigation Lock Filling - Modeled Geometry and Physical Model Measurement Data

Navigation Lock Filling - Modeled Geometry and Physical Model Measurement Data This data set provides the geometry files and physical model measurement data for the filling process of a large navigation lock with a ship in the lock chamber from a water saving basin. The measured data contains water levels, pressure differences, forces on the ship and the opening height of the valves. The lock consists of a lock chamber with a pressure chamber underneath. Both chambers are hydraulically connected with vertical cylindrical filling nozzles inside the floor between both chambers. The three lateral saving basins are connected to the pressure chamber via two lateral culverts each of smoothly varying rectangular shape. Each saving basin has two of these connecting culverts. A vertical lifting valve in each culvert allows the controlled filling operation from the saving basins into the pressure chamber. In the experiment, the lock chamber is filled from the lowest saving basin. The physical model was constructed at a scale of 1:25. The provided data (geometry and model test results) is scaled to prototype scale by Froude's similitude. The data was used in the following publication: Thorenz, C., Schulze, L. (2021): Numerical Investigations of Ship Forces During Lockage. Journal of Coastal and Hydraulic Strucures. Please cite the paper when using the data.

Global particulate organic carbon flux derived from Th-234: 13 ocean regions, 3 export depths

The 234Th–238U disequilibrium technique has been widely used to estimate the amount of particulate organic carbon (POC) exported from surface ocean layers to the deep sea. This method is based on determining 234Th fluxes from vertical 234Th–238U profiles in the water column and converting them into POC fluxes using POC/234Th ratios measured in sinking particles at a given calculation depth. We present here an extensive repository of POC fluxes, together with Th fluxes and POC/234Th ratios. Covering all the global ocean, classified in 13 regions, season and moment of the bloom and calculated at three different depths: i) a fixed depth (100 m) ii) the reference depth in the paper associated to the base of the euphotic zone iii) the 234Th–238U equilibrium depth. To ensure a compilation representative of the global ocean, the dataset were selected using the division areas proposed by the international network JETZON (Joint Exploration of the Twilight Zone Ocean Network); that agreed a division of the oceans in 13 regions based on their contrasted physics and biogeochemical characteristics. The stations from 234Th publications associated to each JETZON region were carefully selected according to their ability to represent regional environmental conditions. Furthermore, station selection was based on essential criteria such as data quality and accessibility, availability of time series, clear definition of export depth, measurements from established programs, e.g. GEOTRACES, and the presence of other additional relevant ancillary data. The data in the compilation are thus organized by region and include geographic coordinates, season, selected export depth, and other key factors (such as a description of the flux evaluation depth or the export depth zone). After 234Th–238U compilation, 234Th fluxes were calculated, when possible, at the three different depths, i), ii) and iii), under the assumption of steady-state conditions, following Le Moigne et al. 2013. Using POC/234Th ratios, POC fluxes are estimated from Th fluxes and both fluxes were included in the repository. POC/234Th ratios were chosen from pump samples, prioritizing particles larger than 53 μm when available. These ratios must be estimated at the flux calculation depth [i), ii) and iii)]. When they were not available at the calculation depth POC/234Th values were interpolated as described in the readme text file. The values of the ratios are included in the repository, specifying the depth at which they were determined and indicating whether they have been interpolated. Similarly, when 234Th, 238U concentrations were not available at the calculation depth, values were interpolated (see readme text file).

METOP GOME-2 - Ozone (O3) - Global

The Global Ozone Monitoring Experiment-2 (GOME-2) instrument continues the long-term monitoring of atmospheric trace gas constituents started with GOME / ERS-2 and SCIAMACHY / Envisat. Currently, there are three GOME-2 instruments operating on board EUMETSAT's Meteorological Operational satellites MetOp-A, -B, and -C, launched in October 2006, September 2012, and November 2018, respectively. GOME-2 can measure a range of atmospheric trace constituents, with the emphasis on global ozone distributions. Furthermore, cloud properties and intensities of ultraviolet radiation are retrieved. These data are crucial for monitoring the atmospheric composition and the detection of pollutants. DLR generates operational GOME-2 / MetOp level 2 products in the framework of EUMETSAT's Satellite Application Facility on Atmospheric Chemistry Monitoring (AC-SAF). GOME-2 near-real-time products are available already two hours after sensing. The operational ozone total column products are generated using the algorithm GDP (GOME Data Processor) version 4.x integrated into the UPAS (Universal Processor for UV / VIS Atmospheric Spectrometers) processor for generating level 2 trace gas and cloud products. The new improved DOAS-style (Differential Optical Absorption Spectroscopy) algorithm called GDOAS, was selected as the basis for GDP version 4.0 in the framework of an ESA ITT. GDP 4.x performs a DOAS fit for ozone slant column and effective temperature followed by an iterative AMF / VCD computation using a single wavelength.

Veredelung von Nassgrünland-Biomasse zu Plattformchemikalien, Verpackungen, Faserguss und Papier

EDELNASS fokussiert auf die stoffliche Verwertung von Aufwüchsen von wiedervernässten Moor-Grünland, welches heterogen in der Artenzusammensetzung ist und oft Bewirtschaftungseinschränkungen unterliegt (z.B. Erntezeitpunkt). Biomasse und ihre Standortparameter von 5 Moorstandorten in ganz Deutschland werden analysiert und hinsichtlich ihrer Anwendbarkeit in 2 Verwertungsverfahren untersucht, getestet und bewertet: (i) Umwandlung in Bioraffinerien zu den biobasierten, hochwertigen Basischemikalien HMF und Furfural und der Optimierung der Verfahren an der Universität Hohenheim. Ebenso wird Lignin als weiteres Produkt hergestellt. Das HMF kann zur Herstellung des recyclebaren, biobasierten Hochleistungskunststoff PEF weiterverarbeitet werden, woraus die Hochschule Albstadt-Sigmaringen nachhaltige Verpackungslösungen entwickelt, (ii) Das Leibniz-Institut für Agrartechnik und Bioökonomie stellt zusammen mit seinen Partnern Faserstoffe aus der Biomasse her und verarbeiten diese weiter zu Papieren und Fasergussformteilen. Kopplungspotentiale von Stoffströmen der Rohstofffraktionen zwischen den Verfahren untersucht, indem Zwischen- und Nebenprodukte der Verfahren in die jeweils anderen Prozesse eingespeist werden. Ziel der Untersuchungen ist es, neue Wertschöpfungsketten auf der Grundlage von Nasswiesen-Bewirtschaftung zu entwickeln, die eine produktive Nutzung von Nassgrünland mit dem Erreichen von Naturschutz- und Klimaschutzzielen verbindet. Für eine zukünftige Honorierung von Ökosystemdienstleistungen vernässter Moore werden Datengrundlagen erstellt: CO2-Bilanz der Verfahren und möglicher Produkte (inkl. bodenbürtiger Emissionen), Entwicklung von Artenvielfalt und Wasserqualität. Die Kosten von der Rohstoffbereitstellung bis zum Endprodukt werden analysiert, um geeignete Betriebsmodelle für die einzelnen Verfahren abzuleiten und beispielhaft in Moorregionen zu projektieren.
