Additional information

No measured data are available for the registered substance.

Short-term toxicity to fish:

Measured data are available for Hydrocarbons, C12-C15, n-alkanes, isoalkanes, <2% aromatics in which the LL50 for Cyprinus carpio was found to be >100 mg/l.

Long-term toxicity to fish:

Measured data are available for Hydrocarbons, C10-C13, n-alkanes, isoalkanes, <2% aromatics, the 32 day NOEC value was ≥100 mg/l based on hatching, survival and growth.

Short-term toxicity to aquatic invertebrates:

Measured data are available for Hydrocarbons, C10-C13, n-alkanes, isoalkanes, <2% aromatics in which a 48 hour EL50 value of >100 mg/l and a NOELR value of ≥100 mg/l (WAF loading rate) were determined for the effects of the test substance on mortality of Daphnia magna.

Measured data are available for Hydrocarbons, C12-C15, n-alkanes, isoalkanes, <2% aromatics in which the EL50 for Daphnia magna was found to be >100 mg/l.

Measured data are available for Hydrocarbons, C14-C16, n-alkanes, isoalkanes, <2% aromatics in which the 48-hour LL50 for Daphnia magna was found to be > 100 mg/l based on WAF loading rate.

Long-term toxicity to aquatic invertebrates:

A computer-based program, Petrotox (PETROTOX-UDM_ver3.01-2006-01438-01-E), was used to calculate the toxicity of hydrocarbon solvent products estimated using the Petrotox model.

For Hydrocarbons, C11-C16, n-alkanes, isoalkanes, <2% aromatics, an estimated 21-day NOELR (No Observed Effect Loading Rate) value of >1000 mg/l based on reproduction of Daphnia magna was determined.

Toxicity to algae and cyanobacteria:

Measured data are available for Hydrocarbons, C10-C13, n-alkanes, isoalkanes, <2% aromatics in which the 72 hour EL50 value of >100 mg/l and NOELR value of ≥100 mg/l (WAF loading rate) (highest concentration tested) were determined for the effects of the test substance on growth rate of Pseudokirchneriella subcapitata.

A second, equally reliable, study for Hydrocarbons, C10-C13, n-alkanes, isoalkanes, <2% aromatics also reports a 72 hour EL50 value of >100 mg/l and NOELR value of ≥100 mg/l (WAF loading rate) (highest concentration tested) for the effects of the test substance on growth rate of Pseudokirchneriella subcapitata.

Measured data are available for Hydrocarbons, C12-C15, n-alkanes, isoalkanes, <2% aromatics in which the EL50 was found to be >100 mg/l and the NOELR was ≥100 mg/l.

Measured data are available for Hydrocarbons, C14-C16, n-alkanes, isoalkanes, <2% aromatics in which the 72-hour EL50 >100 mg/l and NOELR ≥100 mg/l were determined for effects on growth rate based on WAF loading rate.

Microorganisms Toxicity:

For Hydrocarbons, C11-C16, n-alkanes, isoalkanes, <2% aromatics, an estimated protozoan 48-hr EL50 value of >1000 mg/L based on growth inhibition of Tetrahymena elliotti was determined using Petrotox (PETROTOX-UDM_ver3.01-2006-01438-01-E).
