The upcoming European Soil Health Law – chances and challenges for an effective soil protection

The European Soil Strategy for 2030 by the European Commission has set the foundations for an overarching approach to the protection of soils in Europe. In this scientific opinion paper, the German Environment Agency (UBA) lays down its key recommendations for the upcoming Soil Health Law.

Further development of screening tests for the evaluation of potential PBT substances

Assessing the persistency of chemicals in general involves a stepwise approach. This includes cost effective and easy to conduct screening tests, that may lead to a need for more complex, lengthy and expensive tests which try to simulate conditions being more representative for the environmental compartments water, sediment and soil.

Langzeittrends für Trifluoressigsäure in terrestrischen Umweltproben

Trifluoracetat (TFA) ist eine persistente und mobile Substanz. In archivierten Nadelproben der Umweltprobenbank des Bundes wurden zeitliche Trends von TFA-Gehalten in Nadeln der Gemeinen Fichte (Picea abies) und der Waldkiefer (Pinus sylvestris) gemessen. Die Proben stammen aus den Jahren 1985 bis 2022.

Ambitionierter Klimaschutz: Fallstricke und Bedingungen des Gelingens

Die klimapolitischen Anstrengungen in verschiedenen Teilen von Politik, Gesellschaft und Wirtschaft weisen in die richtige Richtung und stellen wichtige Weichen für einen ambitionierten Klimaschutz in Deutschland. Ein Scheitern ist in der Umsetzung jedoch weiterhin möglich, besonders solange Klimaschutz nicht als gesellschaftliche Transformationsaufgabe verstanden wird.

Food web on ice - Investigation of the bioaccumulation of chemicals in an exemplary food chain

Trophic magnification factors (TMFs) have been derived in a variety of different aquatic eco-systems worldwide to investigate accumulation patterns of environmentally relevant chemicals. Not only is the TMF interesting for chemicals’ risk assessment related questions, but also for monitoring aspects under the European Water Framework Directive (WFD).

Development of a bioaccumulation test using Hyalella azteca

A test concept for bioconcentration tests with the freshwater amphipod Hyalella azteca (HYBIT) was recently described. It was shown that the Hyalella bioconcentration factors (BCFs) derived for compounds with different hydrophobic characteristics (log Kow 2.4 – 7.8) show a strong correlation to those from fish tests.

Are substances more persistent than test systems lead to believe? Non-extractable residues: experimental examination of suitable extraction methods in view of a long-term risk for the environment

In transformation tests with organic substances in soil non-extractable residues (NER) are formed which remain there as residues. Some can be released again into the environment in the long-term and should be considered in the persistent assessment. Besides substances properties and soil characteristics the proportion of NER strongly depends on the extraction procedure.

Methoden und Kriterien zur Bewertung der Ökotoxizität von Produkten

Die ökotoxikologische Unbedenklichkeit von Produkten, die in Kontakt mit Regen- oder Sickerwasser zur Verwendung kommen, lässt sich durch standardisierte Ökotoxizitätstests zuverlässig überprüfen. Für Bauprodukte ist eine Kombination normierter Auslaug- und Ökotoxizitätstests (Algen, Daphnien, Fischeier, Leuchtbakterien) sowie Gentoxizitätstests (Ames, umu) heute Stand der Technik.

Vers une protection durable des cultures

Dans la proposition de règlement concernant une utilisation des produits phytopharmaceutiques compatible avec le développement durable, la Commission européenne concrétise l'objectif de réduction de 50 % des pesticides de la stratégie « Farm-to-fork». Le développement d’une agriculture durable est cadrée par une mise en œuvre juridiquement contraignante de la lutte intégrée.
