OECD SIDS p-CRESOL 3. ENVIRONMENTAL FATE AND PATHWAYS ID: 106-44-5 DATE: 24.05.2004 Method : Year : 1982 GLP : no Test substance : other TS: p-cresol, purity > 95 % Result : after 29 weeks no significant CH4 or CO2 formation observed Test condition : incubation at 20 degrees C in the dark with occasional shaking Reliability : (2) valid with restrictions No standard test procedure, but in accordance with generally accepted scientific standards and described in sufficient detail 07.05.2004 (62) Type : anaerobic Inoculum : other: aquifer from a river-groundwater infiltration site, adapted to m-xylene Deg. product : Method : Year : 1987 GLP : no Test substance : other TS: p-cresol, purity ar least 98 % (obtained from Fluka AG, Buchs, Switzerland) Method : Laboratory aquifer column; analysis of influent and effluent by HPLC Result : TS influent conc. 0.19 mM TS effluentconc.
OECD SIDS p-CRESOL 3. ENVIRONMENTAL FATE AND PATHWAYS ID: 106-44-5 DATE: 24.05.2004 Concentration : 54 mg/l related to Test substance related to Deg. product : yes Method : Year : 1989 GLP : no Test substance : other TS: p-cresol, no purity reported Deg. products : 74-82-8 200-812-7 methane Method : black anoxic mud collected from a river inoculated in a mineral medium (10% w/v) Result : non-acclimated consortia: turnover rate 3.00 µmol/day/g sediment dw (lag-phase 12 d) acclimated consortia: turnover rate 6.00 µmol/day/g sediment dw (lagphase 0 d, based on a 24 days incubation period), the CH4 production was 97% of the theoretically possible yield Test condition : incubation at 28 degrees C in the dark cultures were refed with 60 mg/l test substance every 2-4 w for a total of 18 months Reliability : (2) valid with restrictions Study in accordance with generally accepted scientific standards and described in sufficient detail 07.05.2004 (69) Type : anaerobic Inoculum : other: unacclimated sediments Concentration : 1 mmol/l related to Test substance related to Contact time : Degradation : 100 (±) % after 30 day(s) Result : 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 21 to 30 days in unacclimated sediment. p-<strong>Cresol</strong> 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 Reliability : (2) valid with restrictions No standard test procedure, but in accordance with generally accepted scientific standards and described in sufficient detail 07.05.2004 (70) Type : anaerobic Inoculum : other: acclimated sediments Concentration : 1 mmol/l related to Test substance related to Contact time : Degradation : 100 (±) % after 10 day(s) Result : UNEP PUBLICATIONS 217
