Maternally transferred dioxin‐like compounds can affect the reproductive success of European eel
Abstract Reported concentrations of dioxin‐like compounds accumulated in the European eel ( Anguilla anguilla ) were used to perform a risk assessment for eel larval survival, taking into account a modeled amplification of tissue concentrations with a factor of 1.33 during spawning migration.
