Description of key information

Soil toxicity studies of fatty acids, tall-oil, manganese salts are not available. Thus, read-across to the assessment entities soluble manganese substances and fatty acids, tall oil is applied since manganese cations and fatty acid anions determine its fate and toxicity in the environment. Reliable data indicate that themoiety of ecotoxicological concern are manganese cations since the lowest chronic effect concentrations is the 23-d NOEC of 322 mg Mn/kg soil dw for Lactuca sativa. Data for fatty acids, tall oil point to a low (if any) toxic potential to terrestrial plants.
