Description of key information
Additional information
There are no aquatic toxicity studies available for the registered substance. However, measured short-term data are available with freshwater fish, invertebrates and algae for two analogue substances. Measured long-term data are available with fish and invertebrates for one analogue substance.
The key short-term values are:
Fish:
Water accommodated fractions of Hydrocarbons, C8-C11, n-alkanes, isoalkanes <2% aromatics (GS160) and Hydrocarbons, C9-C12, n-alkanes, isoalkanes, <2% aromatics (GS170) produced 96-hour LL50 values of >100 mg/L and NOELR values of 100 mg/L with common carp, Cyprinus carpio. No mortality was observed in the highest dose tested.
Invertebrates:
A 48-hour EL50 value of >100 mg/l and NOELR value of ≥100 mg/l (WAF loading rate) (highest concentration tested) have been determined for the effects of the read-across substance Hydrocarbons, C8-C11, n-alkanes, isoalkanes, <2% aromatics (GS160) on mortality of Daphnia magna.
A 48-hour EL50 value of >100 mg/l and NOELR value of ≥100 mg/l (WAF loading rate) (highest concentration tested) have been determined for the effects of the read-across substance Hydrocarbons, C9-C12, n-alkanes, isoalkanes, <2% aromatics (GS170) on mortality of Daphnia magna.
Algae:
A 72-hour EL50 value of >100 mg/l and NOELR value of ≥100 mg/l (WAF loading rate) (highest concentration tested) have been determined for the effects of the read-across substance Hydrocarbons, C8-C11, n-alkanes, isoalkanes, <2% aromatics (GS160) on growth rate of Pseudokirchneriella subcapitata.
A 72-hour EL50 value of >391 mg/l and NOELR value of ≥391 mg/l (WAF loading rate) (highest concentration tested) have been determined for the effects of the read-across substance Hydrocarbons, C9-C12, n-alkanes, isoalkanes, <2% aromatics (GS170) on growth rate of Pseudokirchneriella subcapitata.
The key long-term values are:
A 32-day NOEC value of ≥100 mg/l (loading rate WAF) (highest concentration tested) has been determined for the effects of the read-across substance Hydrocarbons C9-C12, n-alkanes, isoalkanes, <2% aromatics (GTL Solvent GS170) on hatching, survival and growth of Pimephales promelas.
21-day EL10 and EL50 values of greater than 100 mg/L loading rate WAF, have been determined for the effects of the read-across substance Hydrocarbons C9-C12, n-alkanes, isoalkanes, <2% aromatics (GTL Solvent GS170), on mobility and reproduction of Daphnia magna. The No Observed Effect Loading Rate (NOELR) was ≥100 mg/L loading rate WAF.
Predicted long-term data are available with aquatic microorganisms.
A computer-based program, Petrotox (PETROTOX-UDM_ver3.01-2006-01438-01-E), was used to estimate the toxicity of hydrocarbon solvent products.
Toxicity to microorganisms:
The Hydrocarbons, C9-C11, n-alkanes, isoalkanes, cyclics, <2% aromatics, estimated protozoan,Tetrahymena pyriformis, 48-hr EL50 value for this substance is 0.950 mg/L based on growth inhibition. These data are used as read-across data to Hydrocarbons, C9-C11, n-alkanes, isoalkanes, <2% aromatics.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
