CAS number: 84605-29-8
Studies of this
substance are available for evaluating biodegradation and toxicity to
aquatic vertebrate and invertebrate species.
This substance is not
biodegradable when tested in accordance with OECD 301D. The
biological oxygen demand was <5% of the chemical oxygen demand in both
test concentrations at all sampling dates.
The acute aquatic
evaluated using rainbow trout and was conducted in accordance withOECD
96 h LL (Lethal Loading Rate) 50 value of the substance was determined
to be 4.4 mg/l. The No Observed Effect Loading rate was 3.2 mg/l loading
Then acute toxicity of
this substance also was evaluated in Daphnia (OECD 202). The
48-Hour EL*50 was determined to be 75 mg/L nominal loading rate and the
No Observed Effect Loading rate was 32 mg/l nominal loading rate.
The acute toxicity of
this substance was evaluated in freshwater algae in accordance with OECD
Guideline 201. Exposure
ofScenedesmus subspicatusto the test material gave an EbL50 (72h)
value of 240 mg/L loading rate WAF and an ErL50 (0-72hr) value of 410
mg/L loading rate WAF. The No Observed Effect Loading rate was 220 mg/L
loading rate WAF.
Based on the available
environmental fate and ecotoxicological data for daphnids, fish and
algae, this substance requires classification to the aquatic environment
according to Directive 67/548/EEC, the EU CLP (Regulation (EC) No.
1272/2008). This substance has acute aquatic toxicity between 1-10mg/L
in the most sensitive species, is not readily biodegradable, and has an
estimated log P ≤3.0.
