p-CRESOL
4. ECOTOXICITY ID: 106-44-5
DATE: 24.05.2004
Unsuitable test system. Organisms are of marine origin. Method is not
appropriate for the hazard assessment of chemicals.
07.05.2004 (113)
Type : Aquatic
Species : other bacteria: gentechnologically constructed luminescent bacteria
originating from wastewater treatment plant
Exposure period : 30 minute(s)
Unit : mg/l
EC50 : 21 measured/nominal
Analytical monitoring : No
Method : other: Microtox assay
Year : 1986
GLP : no data
Test substance : other TS: p-cresol, no purity reported
Remark : Inhibition of bioluminescence
Modified microorganisms used which represent the metabolic potentials
present in a wastewater treatment plant and some properties of a marine
organism, but which are not identical to any known species in natural
environments
Test condition : - Wastewater bacteria (Eschericia coli) which were obtained from a
wastewater treatment plant
- Bacteria obtained the luciferase operon of Vibrio fischeri by transfer from
luminescent E. coli
- Incubation at 20 °C
- Result calculated from the difference of the luminescence between
controls and test substance taking into account the light emissions at 0 and
20 °C
Reliability : (3) invalid
