EC50 (72h, Pseudokirchnerella subcapitata) > 2 mg/L
toxicity study was performed to assess the acute toxicity of dicyclohexyl
phthalate to the freshwater algae specie sSelenastrum
The study was conducted under GLP and according to OECD Guideline 201.
The study was conducted in a static system. Algae were exposed to the
substance to a concentration of 2.00mg/L
(limit test only by
freshwater. The test was performed with 3 replicates per test
concentration and 6 replicates for the control. The following OECD 201
validity criteria were met: cell concentration in the control increased
by a factor of 38 within 72h; the mean coefficient of variation of the
daily growth rates were 33% and the coefficient of variation of average
growth rate during the whole test period was 4%. Under
the conditions of the test, the 72 hour ErC50 was above 2.00 mg/L.
