A Guideline Value for Dioxin‐Like Compounds in Marine Sediments
Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 257-271, January 2023., 2023 Abstract Sediments to be dredged as part of the installation of a harbor crossing in Sydney, Australia, contained measurable concentrations of dioxin‐like compounds. To assess the suitability of these sediments for ocean disposal, a defensible sediment quality guideline value (SQGV) for dioxin‐like compounds, expressed as pg toxic equivalent (TEQ)fish ...
