Description of key information

Measured short term toxicity data with the registration substance are available for invertebrates and algae.

Measured data are available for short term toxicity to fish with analogue substances.

There are no measured long term fish or invertebrate toxicity data for the registration substance but studies are available for analogue substances.

The key values are:

Short-term toxicity to fish:

GS215 (C12-C15) 96-hour LL50 >100 mg/l for mortality based on WAF loading rate.

GS310 (C18-C24) 96-hour LL50 >100 mg/l for mortality based on WAF loading rate.

Short-term toxicity to 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 test substance 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 test substance on growth rate of Pseudokirchneriella subcapitata.

Long-term toxicity to fish:

GS190 (C10-C13) 32-day NOELR of ≥100 mg/l for effects on hatching, survival and growth of Pimphales promelas based on WAF loading rate;

GTL Gasoil (C8-C26) 33-day NOELR of 100 mg/l for effects on fish length and dry weight of Pimphales promelas based on WAF loading rate.

Long-term toxicity to aquatic invertebrates and microorganisms:

GTL Gasoil (C8-C26) 21-day NOELR of 32 mg/L for effects on survival and reproduction of freshwater invertebrate Daphnia magna based on WAF loading rate.

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.

An estimated freshwater invertebrate 21-day NOELR (No Observed Effect Loading Rate) value of >1000 mg/l based on reproduction of Daphnia magna was determined for Hydrocarbons, C15-C19, n-alkanes, isoalkanes, <2% aromatics.

An estimated microorganism 48-hour EL50 value of >1000 mg/L based on growth inhibition of Tetrahymena elliotti was determined for Hydrocarbons, C15-C19, n-alkanes, isoalkanes, <2% aromatics.
