Long-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
No effects up to the limit of water solubility of the substance.
NOELR (21 d) = 5 mg/L for Daphnia magna (OECD 211) (hydrocarbons, C13-C16, isoalkanes, cyclics, < 2% aromatics)
NOELR (21 d) = 1 mg/L for Daphnia magna (OECD 202, section 2) (limit test) (hydrocarbons, C11-C13, isoalkanes, cyclics, < 2% aromatics)
Key value for chemical safety assessment
Additional information
There are no data available onlong-term toxicity to aquatic invertebratesof Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics.
Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics consist of hydrocarbon solvents with predominant carbon numbers in the range of C11 to C19. The constituents of this solvent are single isomers as well as mixed solvents of which the primary constituents are branched chain (iso-), and cyclic aliphatic hydrocarbons. Aromatic constituents, if present, represent less than 0.1% of the total volume.
N-paraffins are only present in very low concentrations (<1%).
The carbon numbers in the range of C11 to C19 and initial distillation points (IBP) characterize the source substances. The distillation range of the source substances ranges from 220°C to 350 degree Celsius although some solvents may contain higher boiling material. The benzene and sulphur contents of source substances are low, benzene levels for example are typically <3 ppm.
The toxicology and environmental fate and effects data show that source substances have a similar order of (eco-)toxicological and environmental fate properties as the target substance. Therefore, read-across is performed based on an analogue approach (for details please refer to the analogue justification which is attached in section 13 of the technical dossier).
Water accommodated fractions of hydrocarbons, C11-C13, isoalkanes, < 2% aromatics were tested according to OECD 211 (limit test) and GLP, and produced a 21-d NOELR value of 1 mg/L for Daphnia magna (ExxonMobil 2001), which was the only concentration tested. Water accommodated fractions of hydrocarbons, C13-C16, isoalkanes, cyclics, < 2% aromatics were tested according to OECD 202 (section 2), and produced a 21-d NOELR value of 5 mg/L based on adult immobilization and reduction in reproduction of Daphnia magna (ExxonMobil 1996). These data are used as read-across data to Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics. Based on these data, Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics is not expected to exert chronic toxic effects to invertebrates at saturation.
