Field based and laboratory data of sediment cores from the Lower Havel Inner Delta near Lake Gülpe, Brandenburg (Germany)

Sediment cores were recovered using a hand-held Cobra Pro (Atlas Copco) core drilling system with a 60 mm diameter open corer. One-meter segments were retrieved and assessed in the field for sedimentological features, including estimations of grain size, carbonate content, humus content, and redox features (AG Boden 2005, 2024). Colour descriptions were carried out using the Munsell Soil Color Chart. The exact positions of the drilling points were recorded using a differential GPS device (TOPCON HiPer II). The cores were photographed, documented and sampled at 5–10 cm intervals for subsequent laboratory analyses. Bulk samples from five selected cores (RK1, RK3, RK13, RK15, RK17) were freeze-dried, sieved (2 mm), and weighed. Total carbon (TC), total nitrogen (TN), and total sulfur (TS) contents were measured using a CNS analyzer (Vario EL cube, Elementar). Inorganic carbon (TIC) was determined using calcimeter measurements (Scheibler method, Eijkelkamp). Organic carbon (TOC) was calculated as TOC = TC − TIC. For the grain size analyses, sediment samples were first sieved to <2 mm and subsamples of 10 g were treated with 50 ml of 35% hydrogen peroxide (H₂O₂) and gently heated to remove organic matter. Following this, 10 ml of 0.4 N sodium pyrophosphate solution (Na₄P₂O₇) was added to disperse the particles, and the suspension was subjected to ultrasonic treatment for 45 minutes. The sand fraction was analysed by dry sieving and classified into four size classes: coarse sand (2000–630 µm), medium sand (630–200 µm), fine sand (200–125 µm), and very fine sand (125–63 µm). Finer fractions were determined using X-ray granulometry (XRG) with a SediGraph III 5120 (Micromeritics). These included coarse silt (63–20 µm), medium silt (20–6.3 µm), fine silt (6.3–2.0 µm), coarse clay (2.0–0.6 µm), medium clay (0.6–0.2 µm), and fine clay (<0.2 µm).

Out of Sight – The Insufficiency of the Phase I Action Limit in Veterinary Early Impact Assessment

The VICH GL 6 guideline outlines a tiered assessment scheme that is mandatory for all active substances (AS) used in veterinary medicines before they enter the market. As the first step, the predicted environmental concentration of the AS in question is compared to a so-called “action limit” of 100 μg/kg for soil. If this action limit is exceeded, an extended environmental risk assessment is required. This limit is currently based on data that were recorded between 1973 and 1997 in the USA. Since then, new active ingredients with higher efficacy (and, therefore, potential environmental impacts at lower concentrations) have been developed and put on the market. This consequently elevates the probability of environmental and organismic impact, which in turn affects biodiversity and, ultimately, the natural functioning of ecosystems. A critical evaluation of the action limit is therefore necessary. Does it still serve its purpose as a precautionary decision criterion on whether an experimental Phase II risk assessment must be conducted? To assess the protectiveness of the soil action limit of 100 µg/kg, we evaluated 82 tests (34 plant and 48 earthworm tests) for 18 parasiticides, 28 antibiotic and 5 other AS, using data from European Medicines Agencies Public Assessment Reports, supplemented by internal data of the German Environment Agency. We included parasiticides in the data evaluation, although the action limit does not apply here, as their environmental hazard is determined by their toxicity to insects. Tests between model predictions reveal no difference between models with and without parasiticides (with parasiticides n = 51, without parasiticides n = 33). For each AS, we included the lowest available NOEC/EC10 and fitted a sigmoidal non-linear least squares model in the range of [0,1]. 18±5 % of the NOECs/EC10 values are below 100 µg/kg soil. This reduces to 17±6 % if only non- parasiticides are included in the data analysis. A total of 11 substances are below or equal to the action limit, 7 antibiotics and 4 parasiticides. In order to ensure that the action limit covers approximately 95 % of AS currently on the market, a reduction from 100 to 5 µg/kg would be necessary. The analysis shows that the current action limit is insufficient to protect organisms and ecosystems. In future revisions of the guideline, it will be necessary to adapt the action limit to current scientific standards.

Geophysical, Sedimentological and Geochemical Data from the Lower Havel Inner Delta (Gülpe Island), Brandenburg (Germany)

To investigate subsurface features in the Lower Havel River floodplain, we conducted Electrical Resistivity Tomography (ERT) transects and Electromagnetic Induction (EMI) surveys at three different depths in 2023 and 2024. These near surface geophysical methods were complemented by 24 driving core drillings to relate the electrical properties with sedimentological characteristics. Additionally, five selected sediment cores were used for subsequent geochemical lab analyses (grain size, CNS, TOC, TIC). Electromagnetic induction (EMI) was measured with a CMD-Mini Explorer (GF Instruments s.r.o., Brno, Czech Republic) in June 2023 and June 2024. We used the vertical dipole (VDP) at coil spacings of 0.32 m (VDP1), 0.71 m (VDP2) and 1.18 m (VDP3), archieving effective penetration depths of 0.5 m (VDP1), 1.0 m (VDP2) and 1.8 m (VDP3). According to the manufacturer, 70% of the signal originate from above these depths. The EMI sensors measure the apparent electrical conductivity (ECa, in mS/m). Measurements were taken by carrying the instrument about 0.2 m above ground while being directly connected to D-GPS (Leica GPS1200) for positioning. The acquisition rate was five measurements per second. Data quality was checked by measuring a reference line before and after each measurement. The area investigated by EMI in June 2023 is located to the north and northeast of the Gülpe research station. It has a total area of 12.3 ha. The reference line was located in the southern part of the study area. No drift correction had to be applied due to good data quality. Reference lines and single outliers were removed. The area investigated by EMI in June 2024 is located southeast of the research station. The survey area there is 8.1 ha in size. The reference line for the measurements there was located in the north-westernmost area of the site. No drift correction had to be applied due to good data quality. Reference lines and single outliers were removed. The Electrical Resistivity Tomography (ERT) data were acquired by using a PC controlled DC resistivity meter system (RESECS, Geoserve, Kiel, Germany). In total, we measured four ERT transects. Two transects in June 2023, where transect 1 had a total length of 259 m with an electrode spacing of 0.5 m and transect 2 had a total length of 223 m with an electrode spacing of 1 m. The measurements in 2023 were carried out under extreme dry conditions. Two further transects were measured in June 2024 with an electrode spacing of 1m, transect 3 with a total length of 207 m and transect 4 with a total length of 239 m. We applied wenner alpha and dipol-dipol configuration. The coordinates and the height of the electrodes were measured with a D-GPS (2023: TOPCON HiPer II / 2024: Leica GPS1200).
