The formation and presence of oligomers is inevitable in such FCM. Despite known migration into food, these substances are toxicologically poorly characterized, preventing adequate risk assessment. The ongoing project phase allowed essential new insights into available information on oligomers from all polymeric FCM. A pilot study on PET helped to design an optimized strategy and workflow to address this task. Information on physicochemical, ADME and toxicological properties was collected using computational methods. In a second project phase, a collection of oligomers from all other materials will be made based on the obtained information. The focus will be on bioactivity assessment of these substances. Hazard profiles will be established using various in vitro assays to assess general toxicity, cellular stress pathways, macrophage activation and endocrine effects. These studies aim at assessing the level of concern of such substances and providing recommendations for prioritization of future toxicological testing. ToxOligo - Toxicological properties of oligomers present in food contact materials Research Project | 6 Project MembersToxOligo addresses an important knowledge gap by characterizing toxicological properties of oligomers released from food contact materials (FCM) such as plastics, adhesives, printing inks and coatings. Despite known high levels in FCM, these substances are toxicologically poorly investigated, preventing adequate risk assessment. A systematic review of the literature and expert interviews will provide insight on available knowledge of types of structures involved, exposure estimates and toxicological information. Physico-chemical and ADME properties, reactivity of building blocks, stability of oligomers, genotoxicity, endocrine disrupting potentials, and chronic and developmental toxicity will be predicted by in silico methods. Hazard profiles will be established for relevant selected oligomers using in vitro assays on general cytotoxicity, cellular stress pathways, neuronal cell toxicity, macrophage activation, and endocrine regulation. Selected FCM extracts will be considered to identify potentially hazardous materials. Levels of concern will be estimated, information gaps identified, and recommendations for follow-on toxicological analyses and an evaluation concept for safety assessment of oligomers will be proposed. Smart and Designer Drugs: Toxicoepidemiology of non-medical stimulant use in Switzerland Research Project | 5 Project MembersObjectives of this project are to investigate medical problems associated with stimulant drug use (designer and smart drugs) in Switzerland. The project includes an analysis of the database of the Swiss Toxicological Information Center and retro- and prospective studies at emergency departements at Swiss university hospitals. It is a collaborative project under the auspices of the Swiss Center for Applied Human Toxicology. 1 1 OverviewResearch Publications Projects & Collaborations
