Description of key information
The effect of the test material on the growth of Scenedesmus subspicatus gave EL50 values greater than 100 mg/L Loading rate WAF and a corresponding NOELR of 100 mg/L Loading rate WAF.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
A key study was performed to assess the effect of the test material on the growth of green algae, Scenedesmus subspicatus. The method followed OECD Guideline No 201 and EC Method C3.
Following a preliminary range finding test, Scenedesmus subspicatus was exposed to a Water Accomodated Fraction (WAF) of the test material, at a single nominal loading rate of 100 mg/L (six replicate flasks) for 72 hours under constant illumination and shaking at a temperature of 24 ± 1°C.
The effect of the test material on the growth of Scenedesmus subspicatus gave EL50 values greater than 100 mg/L Loading rate WAF and a corresponding NOELR of 100 mg/L Loading rate WAF.
It was considered unnecessary and unrealistic to test loading rates in excess of 100 mg/L.
