Save the date: Particle Based Materials Symposium 2022 – Enhancing Sustainability 6.-7.10.22

The goal of the Particle Based Materials Symposium is to bring together scientists and engineers from different communities that all share the goal of creating functionality in materials using particles. The synthesis, processing and materials integration of particles into thin films, bulk matrices, fibers or other geometries are covered by this symposium.

Particles and particle-based materials (PBM) are everywhere and will play a crucial role to enhance sustainability of processes and products. The PBM Symposium 2022 thus particularly welcomes contributions dealing with PBM in fields such as energy (generation, storage, transformation), catalysis, recycling, purification and recovery, extension of materials lifetime or damage indication. Besides this, fundamental contributions to better understand the formation or the properties of complex particle systems are very welcome as well.

New advice for determining dose levels in toxicity testing

ECHA has published new advice on choosing the correct substance dose levels for toxicity tests. It helps companies ensure reliable results to conclude on the safety on their chemicals. The clarification comes from the amended REACH annexes which started to apply in January 2022.


Companies need to choose the correct substance dose for their toxicity tests to conclude on the safety of their chemicals. This is clarified in the amended REACH annexes, which apply as of January 2022. ECHA’s advice helps companies ensure reliable results while avoiding repeated animal tests.

The data companies generate from toxicity tests must be adequate for identifying the hazards and assessing the risks of their chemicals. Companies must also prevent severe suffering when carrying out animal tests. Toxicity tests should be done at an appropriately high dose level, in line with the corresponding OECD test guideline. This ensures that a test can be used to conclude whether the chemical is safe to use and that the test does not need to be repeated.

ECHA’s advice on how to apply dose selection for repeated dose toxicity and reproductive toxicity is aligned with OECD guidelines and guidance documents.

ECHA’s Director for Hazard Assessment, Mike Rasenberg says: “The amended REACH annexes and our instructions guide companies to do toxicity tests using the correct dose level. We need to ensure that any test results can reliably show whether a chemical causes severe health effects or not. In doing so, we avoid companies having to redo inconclusive tests and causing more suffering to animals.”

The ECHA guidance document on Information Requirements and Chemical Safety Assessment – Chapter R.7a will be revised to take the amended REACH annexes into account. It will be published later in 2022.

Science barometer 2021

With the Science Barometer, Wissenschaft im Dialog (German organisation for science communication of the scientific community) has, since 2014, regularly determined the attitudes of the population toward science and research in population-representative surveys. What is the level of trust in science? What social role do science and research play in the eyes of the public? How interested are people in scientific topics and what channels do they use to find out about them?

One topic that has also been the subject of much public debate over the past year and a half is the relationship between science and politics. The Science Barometer 2021 therefore also asks about people’s attitudes and opinions on issues and processes of scientific policy advice.

Advanced materials should be safe and sustainable

Advanced materials have the potential to provide technical solutions for pressing global challenges, i.e. for energy revolution, digitalisation, or health care. However, it is currently difficult to derive which advanced materials will be actually used in the future and to what extent the existing legal frameworks or other measures are suitable to address their safety as well as other aspects of sustainability along their life cycle. This document summarises the current perspective of the higher federal authorities ⁠UBA⁠, ⁠BfR⁠ and BAuA aiming to establish good governance of advanced materials to ensure their responsible development, use and end of life considering human and environment safety.
