EC number: 271-138-9 | CAS number: 68516-20-1 A complex combination of hydrocarbons produced by the distillation of products from a steam-cracking process. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C7 through C12 and boiling in the range of approximately 130°C to 220°C(266°F to 428°F).

Description of key information
The terrestrial toxicity was estimated by a QSAR, the PETROTOX computer model. Petrotox is a well-documented and peer reviewed model that is widely used across the chemicals industry. The substances of this category fit within the criteria of the model and there are no reservations about the validity of the model runs. The estimated LL50 values for Folsomia candida ranged from 62.7 to 82.3 mg/kg soil dw. The estimated LL10 values for Folsomia candida ranged from 12 to 15.8 mg/kg soil dw.
Key value for chemical safety assessment
Additional information
The PETROTOX v4.0 model for sediment terrestrial organism calculates the constituent concentration in sediment or soil using the product composition (% mass) along with the total sediment/soil (s/s) loading rate (concentration of the full substance as added to the soil/sediment). The model then uses the equilibrium-partitioning calculations to convert aqueous-based effect concentrations (EC50, mmol/L) to soil or sediment based values (mmol/kg oc) for each constituent using the CTLBB for the soil or sediment organism. Then, it combines the s/s based concentration (mg/kg dw) and the effect concentrations in soil or sediment based values (mmol/kg oc) to compute toxic units for each constituent, which are then summed to determine the overall effect concentration (LC50ss) of the substance.
