Correctly assessing the performance and threats of microorganisms in agricultural soils – identifying meaningful endpoints under field-relevant pesticide, biocide and pharmaceutical exposure

The aim of the MICROSOIL project was to identify meaningful endpoints for assessing the effects of plant protection products, veterinary pharmaceuticals and biocides on microorganisms in agricultural soils. The current risk assessment for plant protection products (PPPs) considers the effects of PPPs on nitrogen turnover by microorganisms in test soils according to the ⁠ OECD ⁠ 216 testguideline. However, this laboratory test does not cover all risks to microorganisms caused by PPPs. Within this project, five alternative methods to assess the effects of chemicals on the soil microbial community were identified, based on a literature review and a scoring system . To compare the sensitivity of these methods to chemicals, laboratory tests were carried out with three soils and six test substances, each. Based on the MICROSOIL results, it is recommended to add an additional test on bacterial function (ISO 20130, enzymatic activity) and a structural test on the effects on mycorrhizal fungi (ISO 10832) to the first tier risk assessment of chemicals. A fingerprinting method to assess the impact on community structure is also recommended but needs to be further elaborated. The results of this project also show that the current risk assessment for veterinary pharmaceuticals may not cover the development of antibiotic resistance in environmentally relevant soil bacteria. This project also investigated the degradation performance of microorganisms after multiple applications of chemicals. Multiple applications of the same substance as well as the presence of another substance in the soil had both positive and negative effects on the degradation rate of the test substances. The results presented here underline the need to update the risk assessment framework for soil organisms, exposed to chemicals and provide concrete suggestions for a new risk assessment scheme.

Biogenic formation of non-extractable residues from pesticides in soil

During microbial turnover of organic chemicals in soil, non-extractable residues (NER) are formed frequently. Studies on NER formation usually performed with radioisotope labelled tracer compounds are limited to localisation and quantitative analyses but their chemical composition is left unknown. Recently, we could show for 2,4-dichlorophenoxyacetic acid and ibuprofen that during microbial turnover in soil nearly all NER were derived from microbial biomass, since degrading bacteria use the pollutant carbon for their biomass synthesis. Their cell debris is subsequently stabilised within soil organic matter (SOM) forming biogenic NER (bioNER). It is still unknown whether bioNER are also formed during biodegradation of other, structurally different compound classes of organic contaminants. Therefore, agricultural soil will be incubated with labelled compounds of five classes of commonly used and emerging pesticides: organophosphate, phenylurea, triazinone, benzothiadiazine and aryloxyphenoxypropionic acid. The fate of the label will be monitored in both living and non-living SOM pools and the formation of bioNER will be quantified for each compound over extended periods of time. In addition, soil samples from long-term lysimeter studies with 14C-labelled pesticide residues (e.g. triazine, benzothiazole and phenoxypropionic acid group) will be also analysed for bioNER formation. The results will be summarised to identify the metabolic conditions of microorganisms needed for bioNER formation and to develop an extended concept of risk assessment including bioNER formation in soils.

Klimarisikoanalyse 2028, Teil 1: Vorbereitung

Das Vorhaben bereitet die nächste Klimarisikoanalyse für Deutschland vor. Es soll ein schlanker Ansatz gewählt werden, beispielsweise soll sich die quantitative Untersuchung von Klimawirkungen auf Klimadaten konzentrieren und die fachlichen Analysen größtenteils literaturbasiert erfolgen. Nach ISO 14091 soll die Risikoanalyse in 3 Schritten durchgeführt werden: 1. Vorbereitung, 2. Durchführung, 3. Kommunikation. Neue Forschungsaspekte umfassen unter Schritt 1 'Vorbereitung' die Weiterentwicklung der Methodik durch die Reduktion auf ein wesentliches Minimum, die verstärkte Verschneidung mit dem Monitoringbericht, sowie sozioökonomische Szenarien als Narrative mit Fokussierung auf ausgewählte Zukunftsthemen und -trends. Im Hinblick auf Schritt 2 'Durchführung' sollen die Bewertung der Klimarisiken und die Ableitung der Handlungsbedarfe die neuen Anpassungsziele berücksichtigen, in der integrierten Auswertung sollen die Kaskadeneffekte auch im Hinblick auf vulnerable Gruppen und Systeme untersucht werden, und die Anpassungskapazitätsbewertung sollen mit vorhandenen ex-ante Maßnahmenbewertung enger verschnitten und auf Lücken und Bedarfe ausgerichtet werden. Im 2. Schritt 'Kommunikation' stehen zielgruppenspezifische Kommunikationsprodukte im Vordergrund. Um die dynamische wissenschaftliche Entwicklung besser abzubilden, wird die KRA in 2 Slots ausgeschrieben werden: Teil I: 2023-2025 Vorbereitung KRA 2028; Teil II: 2024-2028 Durchführung und Kommunikation KRA 2028.

Digitalisation and Sustainability in the European Union: Steps towards new governance approaches for a twin transition

With the 'twin transition', the European Union aims to combine digitalisation and sustainability in order to achieve the United Nations Sustainable Development Goals. The research project "Digitalisation and sustainability at EU level" examined the opportunities and risks of digitalisation for the implementation of the 2030 Agenda for Sustainable Development. The analysis showed that these two topics are often not integrated. Recommendations were developed for digital circular economy, sufficiency and environmental justice. The research findings suggest that environmental and social justice should be at the forefront of future efforts to promote a sustainable digital future. Veröffentlicht in Texte | 35/2025.

Sentinel-5P TROPOMI – Ozone (O3), Level 3 – Global

Ozone vertical column density in Dobson Units as derived from Sentinel-5P/TROPOMI observations. The stratospheric ozone layer protects the biosphere from harmful solar ultraviolet radiation. Ozone in troposphere can pose risks to the health of humans, animals, and vegetation. The TROPOMI instrument aboard the SENTINEL-5P space craft is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infra-red. TROPOMI's purpose is to measure atmospheric properties and constituents. It is contributing to monitoring air quality and providing critical information to services and decision makers. The instrument uses passive remote sensing techniques by measuring the Top Of Atmosphere (TOA) solar radiation reflected by and radiated from the earth and its atmosphere. The four spectrometers of TROPOMI cover the ultraviolet (UV), visible (VIS), Near Infra-Red (NIR) and Short Wavelength Infra-Red (SWIR) domains of the electromagnetic spectrum, allowing operational retrieval of the following trace gas constituents: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4). Daily observations are binned onto a regular latitude-longitude grid. Within the INPULS project, innovative algorithms and processors for the generation of Level 3 and Level 4 products, improved data discovery and access technologies as well as server-side analytics for the users are developed.
