In a static
acute toxicity test performed according to OECD guideline 201, the alga Pseudokirchneriella
exposed for 72 hours to three nominal concentrations ranging between 1
and 100 mg/L of 2237 JG/L. The initial cell concentration was
approximately 10 000 cells/mL.
test item was insoluble in the tested medium, the use of Water
Accommodated Fractions (WAF) for the preparation of the test media was
item stability was checked by the determination of Alkyl Poly Glucosid
(APG) in fresh and old WAF (GC-FID; non GLP data). Because of the
instability of APG under light conditions, actual concentrations of APG
were not in good agreement with the initial concentrations (-42% and
-61% after 72 hours by comparison to initial measurements for 10 and 100
mg/L test concentrations respectively).
obtained showed that at the highest tested concentration of 100 mg/L
(nominal concentration), a toxicity of the test item with an inhibition
of the average specific growth rate in comparison to the control equal
to 22.1% during the first test and 17.3% during the second test.
