Description of key information

NOEC ≥ 1000 mg/kg soil dw (OECD 222; Eisenia fetida)

Key value for chemical safety assessment

Additional information

One long-term study is available on the toxicity of Fatty acids, C18-unsaturated, dimers (CAS 61788-89-4) to soil macroorganisms. The study was conducted according to OECD guideline 222 and GLP (Winkelmann, 2014). The test organism Eisenia fetida was exposed to the test substance at concentrations of 62.5, 125, 250, 500 and 1000 mg /kg soil dry weight for 8 weeks. As no statistically significant effects were observed, the NOEC was determined to be ≥ 1000 mg/kg soil dw.
