Description of key information

Additional information

No terrestrial toxicity data are available.

The provision for short-term terrestrial toxicity testing is contained within Column 1 of Annex IX of REACH. Column 2 of this Annex, describing the Specific Rules for Adaptation from Column 1, states: "These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely."

Direct exposure of the soil compartment to the substance from its manufacture and use (see IUCLID Section 3) is considered negligible. Indirect exposure of the soil compartment might be possible via the spreading of sludge from sewage treatment plants (STPs) to land. However, loss of the substance to STPs during manufacture, and disposal of the substance to STP during use and end of life, is expected to be minimal. During manufacture, all necessary measures are taken to prevent releases to the water table, including no water washing of equipment and the use of waste water traps to limit release due to accidental spillage and rain water run-off. The substance is used as an additive in fuel; therefore, its end of life is its incineration.

The substance is also readily biodegradable (see IUCLID Section 5.2), further limiting the amount of intact substance that might be contained within sewage sludge applied to land.

In addition, the substance has shown no hazardous potential in any of the studies that are available, including mammalian toxicity studies, aquatic ecotoxicity studies, and an activated sludge respiration inhibition test. This further supports the notion that the substance is unlikely to represent a threat to terrestrial ecology and, in accordance with the Standard Information Requirements laid down by REACH (Annexes VII to X), terrestrial toxicity studies do not need to be conducted.
