Poison in fish: chemists at the University of Graz discover new arsenic compounds in herring caviar

We know that potentially toxic trace elements such as mercury and arsenic can accumulate in saltwater fish. They are bound into organic compounds, which can then be found in cellular components such as membranes. Chemists at the University of Graz from Univ.-Prof. Dr. Kevin Francesconi’s working group have discovered the existence of previously unknown arsenic compounds in herring roe. The study was published as a “Very Important Paper” in the renowned chemistry journal Angewandte Chemie. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
