The year 2017 marks the 37th anniversary of the Dioxin Symposia. In 1980, Otto Hutzinger organized the first symposium in Rome, Italy. Since then, annual symposia (except 1983) have been held in cities around the world. Over the past 37 years, there have been major advances in the analytical determination, and the understanding of the transport, fate and toxic behaviour of these compounds. The year 2017 also marks the 150th anniversary of Canada. We will have numerous activities and celebrations showcasing Vancouver and Canada (click for full message).
