DATE: 24.05.2004
3.1.1 PHOTODEGRADATION
308
Type : air
Light source :
Light spectrum : nm
Relative intensity : based on intensity of sunlight
Deg. product :
Method : other (measured)
Year : 1995
GLP : no data
Test substance : other TS: m-cresol, purity > 99 %
Method : Determination of the temperature-dependency of the
OH-radical reaction under simulated tropospheric conditions
Remark : With a OH radical concentration of 1 000 000 molec cm-3 and
a temperature of 299 K, the half-life is 3.8 h
Result : kOH = 5.17 x 10E-12 exp[(686+-231)/T] cm3 molec.-1 s-1 for a
temperature range of 299-373 K
Test condition : test substance concentration 0.05-5 ppm
reference compound (o-cresol) 0.05-2.3 ppm
radical source methylnitrite 1.5-11 ppm together with NOx
2-70 ppm
Reliability : (1) valid without restriction
Test procedure in accordance with generally accepted scientific standards;
detailed documentation of test procedure and test conditions
Flag : Critical study for SIDS endpoint

Type : air
Light source :
Light spectrum : nm
Relative intensity : based on intensity of sunlight
Deg. product :
Method : other (measured): critical review
Year : 1994
GLP : no data
Test substance : other TS: m-cresol, no purity reported
Remark : With a OH radical concentration of 1 000 000 molec/cm3, the
half-life is 3.0 h at room temperature
Result : K[OH] = 64 [10E-12 cm3 molecule-1 s-1]
K[NO3] = 9.74[10E-12 cm3 molecule-1 s-1]
K[O3] = 1.9 [10E-19 cm3 molecule-1 s-1]
Reliability : (1) valid without restriction
Critical review, evaluation of all available experimental
data
Flag : Critical study for SIDS endpoint
