EC number: 692-614-6
CAS number: 5660-53-7
In a reliable study performed on freshwater algae, the substance was found not harmful to algae with a 72-hour EC50 = 598 mg a.i./L and 72-hour EC10 = 262 mg a.i./L.
The substance was tested for toxicity on Pseudokirchneriella
subcapitata in a study performed according to OECD
Guideline 201 and in accordance with GLP.
The freshwater alga, Pseudokirchneriella
exposed to a geometric series of six treatment levels of2-isobutyl-2-methyl-1,3-dioxolane-4-methanol
ranging from 31 to 944 mg
a.i./L, based on mean, measured concentrations of this substance.
Toxicity of 2-isobutyl-2-methyl-1,3-dioxolane-4-methanol to P.
subcapitata was assessed based on
effects on growth rate and yield relative to the negative control group. The
72-hour EC50values for growth rate and yield were determined
to be 598 mg a.i./L and 219 mg a.i./L, respectively. The 72 hour EC10
value for growth rate was determined to be 262 mg a.i./L.
Based on the results of this study, the test item is considered as
not harmful to aquatic plants in accordance with the Regulation (EC)
