Description of key information
In a read across study with Bis- 2,4-dimethylphenoxy-propan-1,3-ol-2 the oxygen consumption rate was measured. The EC10, EC 50 and EC90 values were determined to be 10000 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 10 000 mg/L
- EC10 or NOEC for microorganisms:
- 10 000 mg/L
Additional information
Key
Aim of the read-across study with Bis- 2,4 -dimethylphenoxy-propan-1,3-ol-2 is the determination of bacteriotoxicological effects by measuring the O2 consumption rate. One concentration was tested with 10000 mg/L. The EC10, EC50 and EC90 values were 10000 mg/L.
Supporting
In a short-term respiratory inhibition read across study the effect of Bis- 2,4-dimethylphenoxy-propan-1,3-ol-2 on the effect concentrations were measured according to OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test). Communal activated sludge was used. The effect of the test material was compared with the effect of the reference substance 3.5 -Dichlorphenol. The concentration tested was 978.8 mg/L. The EC10 was 978.8 mg/L. No toxicity effects on the Microorganisms could be observed.
