Description of key information

NOEC (14 d): ≥ 28.4 mg/L for activated sludge microorganisms (OECD 301B)

Key value for chemical safety assessment

Additional information

The toxicity of ethylene diformate (CAS 629-15-2) to microorganisms was investigated in a biodegradation study according to OECD 301B under GLP conditions (Roulstone, 2013). The toxicity control available in this test contained activated sludge of a predominantly domestic sewage, reference substance (sodium benzoate) and the test substance at a concentration of 28.4 mg/L. The toxicity control attained 81% degradation after 14 d of incubation. Since more than 35% degradation was observed in the toxicity control, the substance is with high probability not toxic to aquatic microorganisms. The test item concentration in the toxicity control of 28.4 mg/L can be used as NOEC value for the toxicity to aquatic microorganisms. Thus, a NOEC (14 d) of ≥ 28.4 mg/L resulted.
