Additional information

One long-term study conducted with the earthworm Eisenia fetida, according to the OECD Guideline 222, is available for the subcategory 2 member Fatty acids, C18-unsaturated, dimers (CAS No. 61788-89-4). As no effects occurred in the this study up to the highest test concentration of 1000 mg/kg soil dw, the members of the subcategory 2 predominantly oligomers, are considered as not harmful to terrestrial organisms and no further testing is needed.

As the test substance is not classified as toxic or harmful, it is not expected to cause toxic effects in predators. Additionally, the uptake and bioaccumulation potential is low and thus the test substance is considered to cause no hazard to predators. Thus, a study with birds is not needed due to animal welfare reasons and no PNEC oral is derived from data on mammalian toxicity.
