Gehalt und Entstehung von Mykotoxinen und Nitrosaminen in Nahrungsmitteln

Wegen ihrer Carcinogenitaet und chronisch/toxischer Wirkungen sind Mykotoxine und Nitrosamine bedrohliche Inhaltsstoffe von Nahrungsmitteln. Zur Minderung des Risikos tragen Kenntnisse ueber die Bildungsbedingungen entscheidend bei. Experimentelle Untersuchungen ueber Nachweismethoden, Nachweisgrenzen und Vorkommen der genannten Schadstoffe sowie Kontaminationswege werden in Modelluntersuchungen mit biologischen und physikalisch-chemischen Verfahren durchgefuehrt.

IBÖ-11: PRE7dSh - Entwicklung einer Formulierung des biogenen Totalherbizids 7-Desoxysedoheptulose (7dSh) zur Substitution von Glyphosat als Vorlaufherbizid

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.

Ressortforschungsplan 2021, Ziel des Vorhabens ist die Unterscheidung zwischen einer vergleichenden Risikobewertung und einer per-se Bewertung in einem der sieben Risikobereiche zu analysieren und herauszuarbeiten, welcher Bewertungsansatz für welche Aspekte sinnvoll ist

H2020-EU.3.5. - Societal Challenges - Climate action, Environment, Resource Efficiency and Raw Materials - (H2020-EU.3.5. - Gesellschaftliche Herausforderungen - Klimaschutz, Umwelt, Ressourceneffizienz und Rohstoffe), Land-Based Solutions for Plastics in the Sea

Plastic is pouring from land into our oceans at a rate of nearly 10 million tonnes a year. Once in the sea, plastics fragment into particles moving with the currents and ocean gyres before washing up on the coastline. The smaller the size the higher the risk posed by these particles to organisms and human health. EU-funded LABPLAS will develop new techniques and models for the quantification of small micro- and nano plastics (SMNP). Specifically, LABPLAS will determine reliable identification methods for more accurate assessment of the abundance, distribution, and toxicity determination of SMNP and associated chemicals in the environment. It will also develop practical computational tools to facilitate the mapping of plastic-impacted hotspots and promote scientifically sound plastic governance. Objective: There are 5,250 billion plastic particles floating on the surface on the world's seas and oceans, equivalent to 268,940 metric tons of waste. These fragments move with the currents before washing up on beaches, islands, coral atolls or one of the five great ocean gyres. Because MP cannot be removed form oceans, proactive action regarding research on plastic alternatives and strategies to prevent plastic entering the environment should be taken promptly. Despite the research increasing, there is still a lack of suitable and validated analytical methods for detection and quantification of small micro- and nano plastics (SMNP) evidencing a huge obstacle for large-scale monitoring. There is also a lack of hazard and fate data which would allow their risk assessment. LABPLAS is a 48-months project whose vision is creating capacities (sampling, analysis and quantification techniques, new materials and new models) to evaluate rapidly and precisely the interactions of plastics with the environmental compartments and natural cycles leading to the development of effective mitigation and elimination measures, as well as, making management decisions. It will assess reliable identification methods for more accurate assessment of the abundance, distribution and toxicity determination of SMNP in the environment, giving the opportunity of new developments of cutting edge technologies. It will also develop practical computational tools that up-scaled should allow European agencies to map plastic-impacted hotspots. The project will have a multi-actor approach, creating scientific knowledge with a partnership of scientists, technicians, research organizations and enterprises, working together towards the recognition at different levels (society, industry, policy) of the main issues (sources, potential biodegradability, ecotoxicology, ingestion, environmental assessment) related to the presence of plastics in ecosystems.

Global compilation of Rare Earth Element concentrations in biological, sediment and water samples from 1973 to 2023

Over the past 30 years, the significant increasing exploitation of Rare Earth Elements (REEs) for their use in new technologies (e.g. low-carbon energy, multimedia, medicine) has led to their release into the environment. The occurrence of these emerging contaminants in the environment leads to major health and environmental issues. In the last decade, a growing number of studies have observed the presence of anthropogenic REEs in freshwater and marine aquatic organisms. However, limited information is currently available regarding the natural levels of REE concentrations in aquatic organisms. A global understanding of these natural levels is therefore essential to: i) understand the natural biogeochemical cycles of REEs; ii) gain better insights into the risks of exposure associated with anthropogenic REEs; and iii) determine research perspectives by evaluating current knowledge gaps. This dataset compiles concentrations for the 14 stable REEs, from lanthanum (La) to lutetium (Lu), and sum of REE concentrations (∑REE). These data were compiled from 102 articles published over the last 50 years, between April 1973 and January 2023. These articles provided at least one concentration value for one REE in one aquatic organism, regardless of the analyzed tissue (e.g. whole organism, leaf, liver, shell). A total of 15,710 concentration data were compiled for aquatic organisms. The REE concentrations were compiled for in situ aquatic organisms (expressed in µg.kg-1). The available concentration data for water (n=2105; in µg.l-1) and sediment samples (n=1125; in µg.kg-1) from these studies were also compiled. These field data span across a global scale, encompassing both freshwater and marine ecosystems. The REE concentrations were associated with various biological parameters (e.g. Phylum, Species, Habitat, Tissues) and spatial parameters (e.g. Ecosystem, Area). For each of these parameters, the most precise information was obtained from the published articles providing these data. Additionally, the data were classified based on the presence or absence of environmental REE contamination at the sampling site. Further complementary information is available in the dataset (ReadMe tab). The reference for each of the cited articles is also provided in the dataset (References tab).

Material Prosperity and Climate Protection

The study analyses which key trends in the economy and society influence the material foundations of prosperity in Germany. It also shows how the key trends represent both opportunities and risks for climate protection. Among other things, it focuses on the growing climate impact costs for private households, the increasing pressure to invest in the expansion of resilient infrastructure and the readjustment of industrial policy in geopolitically uncertain times. In the spirit of strategic foresight, the trends are analysed and exaggerated in mini-scenarios up to 2040 in order to derive the need for action. The publication addresses decision-makers in politics and administration as well as experts in environmental and climate protection.
