Conclusion on classification

Short-term toxicity to fish:

Oncorhynchus mykiss; OECD TG 203; read-across.

96-h LL50 value of greater than 100 mg/L loading rate WAF

Short-term toxicity to aquatic invertebrates:

Daphnia magna; OECD TG 202. Read-across

48-h EC50 > 5.62 mg/L (measured) (100 mg/L nominal loading rate WAF)

Toxicity to aquatic algae:

Pseudokirchneriella subcapitata; OECD TG 201. Read-across

Results based on initial nominal loading rates (WAFs):

72 -h ErL50 > 100 mg/L; 72 -h NOErLR = 12.5 mg/L

Results based on initial measured concentrations:

72 -h ErC50 > 28.92 mg/L; 72 -h NOErC = 6.53 mg/L

Substance is readily biodegradable.

Acute toxicity - not classified
