6PPD & 6PPD-quinone: Understanding and Mitigating the Emerging Global Contaminants

September 28, 2023 5:00pm to 6:15pm

The Interstate Technology & Regulatory Council (ITRC) together with the Australasian Land and Groundwater Association (ALGA) is holding a Workshop on the emerging contaminants, 6PPD and 6PPD-quinone. The Workshop will feature speakers from the United States, Australia, and Europe (NICOLE). The aim of this Workshop is to provide background on 6PPD and 6PPD-quinone, review the environmental and health risks, and highlight what is being done globally to find a solution. Time will be allotted for audience questions and answers. 

6PPD-quinone was an unknown chemical until 2020 when Tian et al. identified it as the toxic agent killing coho salmon in Washington State. 6PPD-quinone is a reaction product of ozone and 6PPD, a tire anti-degradant that has been used for decades throughout the world and is recognized as one of the most toxic chemicals compared to substances with USEPA aquatic life criteria. In the short time since 6PPD-quinone's isolation and characterization, scientists have been working to better understand its prevalence and behaviors in the environment. Science is emerging rapidly; this webinar will provide a brief overview of the current understanding of 6PPD-quinone sources, exposure, fate, transport, toxicity, and mitigation strategies. This webinar will also highlight policies, regulations, and government actions related to 6PPD-quinone from Australia, New Zealand, the EU, and the US.
