International Support

The Organization and Scientific Committee of Dioxin2020 together with the International Advisory Board express their gratitude to the French public partners and the international private sponsors for their strong support during the scientific event post-cancellation management phase.

These companies, specialists in persistent organic pollutants both in providing high quality reference standards, specific consumables necessary for their quantification and their high performance measurement by mass spectrometry, did not hesitate for a moment to grant part or all of the amount planned for their sponsoring budget to the Dioxin2020 Organization Committee in order to limit the losses incurred by the cancellation of the symposium.

We thank them for their generous support and strongly encourage you to register and participate in their webinars.
