p-CRESOL
3. ENVIRONMENTAL FATE AND PATHWAYS ID: 106-44-5
DATE: 24.05.2004
Deg. product : yes
Method :
Year : 1990
GLP : no
Test substance : other TS: p-cresol, no purity reported (obtained from Aldrich)
Deg. products : 123-08-0 204-599-1 4-hydroxybenzaldehyde
65-85-0 200-618-2 benzoic acid
74-82-8 200-812-7 methane
99-96-7 202-804-9 4-hydroxybenzoic acid
Method : Sediment samples from a freshwater pond; degradation tested
under three reducing conditions: denitrifying, sulfidogenic, and
methanogenic
Result : TS was completely utilized within 6 to 10 days in acclimated sediment. p-
Cresol degradation proceeded through p-hydroxybenzaldehyde and p-
hydroxybenzoate under methanogenic and denitrifying conditions. Under
methanogenic conditions, also dehydroxylation to benzoic acid took place
Test condition : - 30 degrees C in the dark
- head space gas in the methanogenogenic and sulfidogenic cultures:
CO2/N2 (30 %/70 %)
- head space gas in the denitrifying cultures: argon
- cultures were acclimated to p-cresol by 2 - 3 feedings of p-cresol
Reliability : (2) valid with restrictions
No standard test procedure, but in accordance with generally accepted
scientific standards and described in sufficient detail
