CAS number: 80793-17-5
No studies are available on hydrolysis, photolysis in water or
atmospheric degradation. Hydrolysis however is not expected based on the
molecular structure of the test substance.
In a GLP-compliant, OECD 301C Modified MITI test biodegradation of
AC-6000 was tested using activated sludge prepared from several sampling
sites (return sludges from both city and industrial sewage treatment
plants and surface water and surface soil). The test item was found to
be not readily biodegradable after 28 days (Kurume Laboratory, 2006a).
Simulation studies were not performed.
The degradation rate constants used in the assessment are:
Degradation for hydrolysis
Degradation for photolysis
Degradation rate in air
Degradation rate in the STP
Degradation rate in surface water
Degradation rate in aerated sediment
Degradation rate in soil
The Koc of AC-6000 determined using the HPLC-method is 19,600 (log value
= 4.29). This value is used in the assessment.
Further studies on transport and distribution of AC-6000 in the
environment are not available
The bioconcentration of AC-6000 in fish was studied according to OECD
guideline 305 (Kurume Laboratory, 2006b). Bioaccumulation of AC-6000 in
carp (Cyprinus carpio) was tested at 0.1 and 1 μg/L under
flow-through conditions. The steady-state bioconcentration factors (BCF)
were 2,400 L/kg at 0.1 μg/L and 2,600 L/kg at 1 μg/L. The BCF of 2,600
L/kg is used in the assessment.
