Description of key information

No toxicity studies have been carried out on sediment with registration substance. PETROTOX v4.01 predicted 28-d LL50(mortality) of this substance to Lumbriculus variegatus of 1,400 mg/kg sediment dw and the 28-d EL10(reproduction/biomass) of 268 mg/kg sediment dw.

Key value for chemical safety assessment

Additional information

The registered substance is a complex petroleum UVCB whose constituents have variable physicochemical properties. Therefore, a modeling framework is needed to account for the bioavailability of the constituents in the mixture, which was then used to predict the toxicity of the substance as a whole. The target lipid model (TLM) and HC5, have been applied to soils and sediment using equilibrium partitioning (EqP) model. As such, modeled data are considered fit for purpose. The model used for the calculations was the PETROTOX v4.0 model. PETROTOX is a well-documented and peer reviewed model that is widely used across the chemicals industry.
