Description of key information

The terrestrial toxicity was predicted by a QSAR, the PETROTOX v4.0 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 predicted EL50 values for Avena sativa ranged from 410 to 1327 mg/kg soil dw. The predicted EL10 values for Avena sativa ranged from 78.5 to 254 mg/kg soil dw.
The predicted EL50 values for Brassica rapa ranged from 265 to 857 mg/kg soil dw. The predicted EL10 values for Brassica rapa ranged from 50.7 to 164 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.
