On April 20, 2022, Germany’s Federal Institute for Risk Assessment (BfR) announced that the fourth joint symposium on nanotechnology will be held May 30-31, 2022. During the symposium, experts will present their findings on topics such as the use of nanotechnology in textiles and packaging, its application in agriculture, the effects of nanomaterials on the body, and future-oriented assessment approaches. BfR notes that with nanotechnology, consumer protection is expanding into new scientific realms in many areas. BfR is researching a variety of projects to elucidate the modes of action, to analyze complex samples, and to perform grouping approaches to advance health-related risk assessments of new materials. With the nanotechnology symposium, BfR will foster a regular, interdisciplinary, and interdepartmental exchange of knowledge. The symposium is open to the public. The registration deadline is May 20, 2022.
