EC number: 926-564-6
CAS number: 1179964-22-7
substance is an UVCB and no information about the correlation between
molecular weight and the structural formula of the test item are
available, Water Accommodated Fractions (WAFs) were used to test effects
at different effective loadings. The content of the water soluble
fractions of the test item during the exposure period was verified by
Acute toxicity to fish: No
toxic effects against fish were observed at the limit of water
solubility under exposure conditions (96 h-LL50 > 100 mg/l). The results
are expressed in terms of Lethal Loadings (LL).
Acute toxicity to daphnia: After
48 hrs an EL-50 of higher than 100 mg/l was measured. The result is
expressed in terms of Effective Loadings (EL). No toxic effects against
Daphnia were observed at a limit test concentration at the limit of
water solubility under exposure conditions.
Toxicity to freshwater algae: An
ErL50 of > 100 mg/L was determined and a NOEL[r] of 100 mg/L was
calculated. The results are expressed in terms of Effective Loadings
(EL). No toxic effects against algae were observed at the limit of water
solubility under exposure conditions.
Toxicity to microorganisms: After
three hours the test material showed 11.11 % respiration inhibition of
activated sludge at the highest concentration of 1000 mg/L. An EC-50
value of higher than 1000 mg/l and EC-10 value of 856.5 mg/l was
determined (by probit analysis).
toxicity studies mentioned above are classified as acceptable and
satisfy the guideline requirements
