Since 1998, The Contaminated Site Clean-Up Information (CLU-IN) website has presented Internet Seminars covering a wide variety of technical topics related to hazardous waste characterization, monitoring, and remediation. For each seminar topic, we have selected the highest-quality offering for placement in our archives. Beginning in May 2005, we began offering these archives via podcast, and this feed contains all seminars archived in the last 6 months. For a complete list of seminars archived since 2000 and videos of selected seminars archived since 2012, please visit http://clu-in.org/live/archive/. Our Rehabilitation Act Notice for reasonable accommodation is available at http://clu-in.org/training/accommodation.cfm. CLU-IN was developed by the U.S. Environmental Protection Agency (EPA) but is intended as a forum for all waste remediation stakeholders.

Audio for "6PPD & 6PPD-quinone: Understanding and Mitigating the Emerging Global Contaminants," Sep 28, 2023
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. Organization Information: The Interstate Technology and Regulatory Council (ITRC) is a program of the Environmental Research Institute of the States (ERIS). ITRC is a state-led organization composed of members from state agencies, federal government, the private sector, academia, and community stakeholders. ITRC members participate in technical teams which produce free tools, resources, and training courses for environmental professionals and the public. The Australasian Land & Groundwater Association (ALGA) provides a forum and identity for the Australasian contaminated land and groundwater industry and supports the many professionals working in the field. The core focus of this association is to support advances in the prevention, assessment and remediation of contaminated land and groundwater. NICOLE is the leading European network combining industry, service providers and academics, formed in 1996 with the aim to develop and share state-of-the-art solutions for sustainable risk-based management of impaired land.
