EC number: 271-264-4 | CAS number: 68527-23-1 A complex combination of hydrocarbons produced by distillation of products from a steam-cracking process. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C7 through C9 and boiling in the range of approximately 110°C to 165°C (230°F to 329°F).

The QSAR predicted 14-d EL50 (seedling emergence) and 21-d EL10 (growth) of the UVCB substance for Avena sativa were 372 and 71.2 mg/kg soil dw, respectively. The QSAR predicted 14-d EL50 (seedling emergence) and 21-d EL10 (growth) of the UVCB substance for Brassica rapa were 240 and 46 mg/kg soil dw, respectively. 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. This substance fits within the criteria of the model and there are no reservations about the validity of the model runs. It is expected that this data is reliable with restrictions.

- Conc. based on:
- other: QSAR prediction
- Basis for effect:

- Remarks on result:
- other: QSAR predicted value
- Validity criteria fulfilled:
- yes
- Conclusions:
- The QSAR predicted 14-d EL50 (seedling emergence) and 21-d EL10 (growth) for A. sativa were 287 and 55.1 mg/kg soil dw, respectively.
The QSAR predicted 14-d EL50 (seedling emergence) and 21-d EL10 (growth) for B. rapa were 186 and 35.6 mg/kg soil dw, respectively. - Executive summary:
The QSAR predicted 14-d EL50 (seedling emergence) and 21-d EL10 (growth) of the UVCB substance for Avena sativa were 287 and 55.1 mg/kg soil dw, respectively. The QSAR predicted 14-d EL50 (seedling emergence) and 21-d EL10 (growth) of the UVCB substance for Brassica rapa were 186 and 35.6 mg/kg soil dw,respectively. 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. This substance fits within the criteria of the model and there are no reservations about the validity of the model runs. It is expected that this data is reliable with restrictions.
