Description of key information
NOEC (56 d) = 750 mg a.i./kg soil dw for Eisenia fetida
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 750 mg/kg soil dw
Additional information
Since no studies on toxicity to soil organisms are available for AES (C12-13, 1-2.5EO) Na (CAS 161074-79-9) a read-across approach from a comparable AES (C12 -14, 2EO) Na (CAS 68891-38-3) was applied.
In this test individuals of Eisenia fetida were exposed to different test concentrations of AES (C12 -14, 2EO) Na (CAS 68891-38-3). The study was performed according to OECD guideline 222 and GLP. The NOEC (56 d) for body weight change and reproduction was determined as 750 mg a.i./kg soil dry weight. Up to the highest test concentration (750 mg a.i./kg soil dry weight) no mortality was observed (BASF, 2012).
