4. ECOTOXICITY ID: 108-39-4
DATE: 24.05.2004
Type : aquatic
Species : other bacteria
Exposure period :
Unit :
Analytical monitoring : no
Method : other
Year : 1985
GLP : no
Test substance : other TS: m-cresol, purity 99.5 %
Method : 6 different pure bacteria cultures: 3 isolated from a
laboratory activated sludge, 2 from activated sludge from a
municipal plant receiving some industry wastewater, and 1
from a lake sediment
Effect: 50 % resazurin reduction (determination of
dehydrogenase activity)
Result : from laboratory sludges: EC50 = >500, 225, and 410 mg/l
from activated sludges: EC50 = 360 and >500 mg/l
from lake sediment: EC50 = >500 mg/l
Test condition : 21 degrees C; incubation 30-60 min
Reliability : (2) valid with restrictions
No standard test procedure, but in accordance with generally
accepted scientific standards and described in sufficient
detail
