Description of key information
low toxicity to terrestrial dwelling organisms
Additional information
No terrestrial toxicity data are available for 'Paraffin waxes (Fischer–Tropsch), full-range, C15–C50 branched and linear'. However, toxicity studies for related GTL-derived substances in the relevant carbon number range are available with soil macroorganisms (Eiseinia foetida), terrestrial plants (Glycine max, Lycopersicon esulentum, Sinapis alba, Avena sativa, Lolium perenne) and soil microorganisms.
For GTL Gasoil (covering the carbon range from C8 to C26) a short-term and a long-term soil organism toxicity study is available for earthworms (E. foetida), which both indicate that the test substance is of low toxicity: NOEC (14-d and 28-d) ≥1000 mg/kg dw, based on mortality and reproduction.
GTL Gasoil was also tested with a series of plants in growth studies which also indicated the low toxicity of the test substance. The lowest EC50 (21-d) was 990 mg/kg dw with L. perenne based on growth, while the lowest NOEC (21-d) was 560 mg/kg dw recorded with S. alba also based on growth.
A nitrogen transformation test with GTL Gasoil resulted in an EC50 (28-d) value of 320 mg/kg and a NOEC (28-d) of 180 mg/kg based on nitrate formation rate.
Several studies with terrestrial organisms are available with GTL Base Oil Distillates. A short-term and a long-term toxicity study are available with the earthworm Eisenia foetida. The studies reported respectively a 14-day LC50 value of >1000 mg/kg dw and a 4 week NOEC value of ≥1000 mg/kg dw. A nitrogen transformation test resulted in an EC50 (28-d) value of >1000 mg/kg based on nitrate formation rate.
Additionally, in a plant seedling emergence and growth test five plant species, three dicotyledonous species, soybean (Glyicine max), tomato (Lycopersicon esulentum) and mustard (Sinapis alba) and two monocotyledonous species, oat (Avena sativa) and perennial ryegrass (Lolium perenne) no effects were recorded after 21 or 22 days exposure up to a concentration of 1000 mg/kg dw.
Supporting studies for toxicity to honeybees (OECD 213 and 214) and terrestrial plants (OECD 208) are also available for the substances GS270 (C15-C19) and GS 310 (C18-C24), which add further evidence for the lack of toxicity of hydrocarbons in the relevant carbon range to terrestrial organisms.
Conclusion
Overall, the studies indicate that GTL Gasoil and GTL Base Oil Distillates exhibit low toxicity to terrestrial dwelling organisms. These are used as read across data to 'Paraffin waxes (Fischer–Tropsch),full-range, C15–C50 - branched and linear'.
