A study was performed to assess the effect of the test item on the growth of the green alga Desmodesmus subspicatus following OECD Guideline 201. No efects were observed at a nominal test concentration of 0.32 mg/L (0.065 mg/L measured), the highest attainable test concentration that could be attained due to abiotic (and possibly biotic) degradation properties of the test substance. As no effects were found at the highest concentration attainable, no EC50 or NOEC can be provided for this endpoint
The study was performed to assess the effect of the test item on the
growth of the green alga Desmodesmus subspicatus following OECD
Guideline 201 and having due regard to the amount of auxiliary solvent
permitted in the test under the OECD Guidelines. Based on the geometric
mean measured test concentrations, exposure of the alga to the test item
gave EC50 values of greater than 0.065 mg/l and correspondingly the NOEC
was considered to be 0.065 mg/l, the maximum attainable concentration
under the conditions of the test. However, these values were a result of
unavoidable loss of test substance due to abiotic (and possibly biotic)
degradation of the test substance under the conditions of the assay and,
as no effects were observed over the entire test, they cannot be used to
derive an EC50 or a NOEC.
