Welcome Message


Dear Colleagues

We would like to invite you to participate in the 42nd edition of the International Symposium on Halogenated Persistent Organic Pollutants DIOXIN2022 to be held in New Orleans, Louisiana, USA. After a rocky two years we are excited to have the scientists from all around the world to meet IN PERSON again and have a vibrant discussions and interactions, without which the progress in science is not possible. We are aiming at a scientific program that will cover prominent issues that have emerged in recent years. This will also include (but not limited to) new aspects of persistent pollutants such as fluorinated compounds, micro- and nano-plastics, electronic wastes, and new classes of brominated flame retardants.

New Orleans offers not only a great location for science but also an opportunity to relax and celebrate together reunion after two years of remote meetings. We have prepared for that an amazing social program, which can be experienced exclusively in New Orleans and Louisiana. At the end, it is a place of jazz, carnivals, and cuisine.

Lessez les bone temp rule.
