One reliable Guideline study is available.
The test was performed according to the recommendations of the OECD
The purpose of this study was to determine the inhibitory effect of the
test item on the growth of the fresh water unicellular green alga
Scenedesmus subspicatus. Exponentially growing cultures of this algal
species were exposed to various concentrations of the test item under
defined conditions. The ErC50 (growth rate), ErC100 (growth rate) and
NOEC was estimated for a period of 72 hours.
Following results were determined:
72 -h NOEC: 800 mg/l
72 -h EC50: > 800 mg/l
72 -h EC100: > 800 mg/l
