The 72-hour results of the algal growth
inhibition test including effect concentrations based onnominal (loading
rate) concentrations are summarized
Mean Cell Density (cells/mL)x 104
at 72 hours
(as growth rate)a
a: Negative values indicate a
stimulatory effect relative to the control.
The results in this study are consistent with all validity
criteria and the test is valid according to the guidelines of this
study. No deviations from test guidelines or other incidents occurred
during the course of the reported test which may have influenced the
No effects on growth rate of Desmodesmus subspicatus up to the
water solubility limit (< 0.05 mg/L; OECD 201).
One GLP Guideline study according to OECD 201 is available
investigating the toxicity of fatty acids, C8-10, C12-18-alkyl esters
(CAS 95912-86-0) to aquatic algae (Salinas 2013). Desmodesmus
subspicatus was exposed to nominal loading rates of 10, 32, 100, 320 and
1000 mg/L for 72 h (Water Accommodated Fraction). No effects were
observed on growth and yield after 72 h of incubation resulting in an
EL50 (72 h) > 1000 mg/L and a NOELR (72 h) ≥ 1000 mg/L. Based on the
result it can be concluded that fatty acids, C8-10, C12-18-alky esters
(CAS 95912-86-0) will not exhibit effects on aquatic algae up to the
water solubility limit.
