The study of Migchielsen (2016), investigating the acute toxicity of T001036 to algae according to OECD guideline 201, was considered as the key study for endpoint coverage. The 72-h ErC10 and 72-h ErC50 for growth rate were determined to be 31 mg/L and 86 mg/L respectively.
A well-designed growth inhibition study was performed by
Migchielsen (2016) in which Pseudokirchneriella subcapitata
was exposed to 1.0, 3.2, 10, 32 and 100% of a SS prepared at
nominally 100 mg/l of test substance (five concentrations tested +
1 control) during 72 hours. Analyses showed that measured test
item concentrations were in agreement with the nominal concentrations
(93-97%, despite the filtration) and that they remained stable during
the test period. Hence, it was justified to base all further results and
the toxicity parameters on nominal concentrations.
The measured 72-hour ErC50 was determined to be 31 mg/L, the 72-
hour NOErC and ErC10 were 10 mg/L and 31 mg/L respectively.
Based on the results it can be considered that T001036 is harmful to
