Reference
- Reference substance name:
- Unnamed
- IUPAC name:
- BF 490-1
- Identifier:
- common name
- Identity:
- BF 490-1
- Details on transformation products:
- DT50 = 38 days
DT90 = 127 days
- Description of biotransformation pathway: BAS 490 F is demethylated to the corresponding acid BF 490-1. No further intermediate was detected because the simple aromatic structure of SF 490-1 allowed rapid degradation. CO2 and "bound residues" were found to be the dominating products of biodegradation. - Residues:
- yes
- Details on results:
- - Amount of residual radioactive residues: maximum of 0.212 mg/kg reach at Day 90 until Day 183
- Humic substances: most radioactivity was found in humins, only minor amounts could be dissolved
- Mineralisation rate: after 90 days about 1/5 of IRR was mineralized, after 146 days about 1/4 was mineralized
