4. ECOTOXICITY ID: 106-44-5
DATE: 24.05.2004
Unit : mg/l
LC50 : = 15.5
Limit test :
Analytical monitoring : no
Method :
Year : 1969
GLP : no
Test substance : other TS: p-cresol, purity of "practical grade"
Method : 10 acclimated fish exposed per concentration, 20 served as
control
Result : LC50 (24 h) = 60.3 mg/l
LC50 (48 h) = 50.8 mg/l
at concentrations of 30 to 150 mg/l, the approximate
incidences of surfacing were 30% during the first 10 minutes
Test condition : 12 degrees C; reconstituted water
Reliability : (2) valid with restrictions
Study in accordance with generally accepted scientific
standards and described in sufficient detail

Type : flow through
Species : Oncorhynchus mykiss (Fish, fresh water)
Exposure period : 96 hour(s)
Unit : mg/l
LC50 : = 7.5
Limit test :
Analytical monitoring : yes
Method : other
Year : 1984
GLP : no data
Test substance : other TS: p-cresol, purity not noted
Method : Bioassays were conducted at 0 (control), 10, 18, 32, 56, and
100% of the maximum test concentration. Ten fish were
exposed at each concentration. The fish weighed between 1
and 4 g each. Bioassays were repeated 3 times. Chemicals
were added to the water by a Hamilton Syringe pump to create
the 100% concentration. Dilutions were done by a
Mount-Brungs diluter. Each bioassay tank contained 14
liters of water and the flow per tank varied between tests
from 21 to 111 ml/min, depending upon how much chemical was
available. The tanks were not aerated, to reduce
volatilization. The levels in water of most water-soluble
test compounds were measured daily. The assay method was
the measurement of the absorbance of the ultraviolet light
by the test solutions in a quartz cell with a 1 cm path
length. Concentrations were calculated by reference to
standard curves of the chemical dissolved in the control
tank water.
