3. ENVIRONMENTAL FATE AND PATHWAYS ID: 108-39-4
DATE: 24.05.2004
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 1.10 µmol/day/g
sediment dw (lag-phase 16 d)
acclimated consortia: turnover rate 2.37 µmol/day/g sediment dw (lagphase
0 d, based on a 24-days-incubation period), the CH4 production was
96 % 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
No standard test procedure, but in accordance with generally accepted
scientific standards and described in sufficient detail
