The acute toxicity of the test substance was tested on
fish, invertebrated, algae and microorganisms.
All the studies were reliable and conducted following the
appropriated OECD or national guidelines by GLP standards.
Acute toxciity to the guppies (Poecilia reticulata)
showed a 96 hour LC50 of 280 mg/L and NOEC for mortality and other
effects was 250 mg/L (Groeneveld
et al, 1992).
Short-term toxicity test to the water flea, Daphnia
magna, resulted on an estimated 48 hour EC50 of 204 mg/L (Hisgen,
The toxicity to the algae Desmodesmus subspicatus examined
in a static 72 -hour toxicity resulted in 72 -hour ErC50 (growth
rate), EbC50 (integrated biomass) of 2616 and 1217 mg/L, respectively.
NOEC for for both endpoints was 256 mg/l (Werner,
putida microbial inhibition was tested. Significant
inhibition of cell multiplication occurred at calculated test
concentrations of 63 mg/L and higher. The EC50 was calculated to be 1260
mg/L and the corresponding. NOEC was 32 mg/L (Jansen
& van den Berg, 1992).
Long-term toxicity studies to aquatic
organisms are not required as the substance is readily biodegradable
indicating that long-term exposure and toxicity is not expected in the
aquatic environment. Furthermore, according to Annex IX column 2 of
REGULATION (EC) No 1907/2006, long-term toxicity aqautic study are not
required as the CSA shows low/no risk to the environment.
