3. ENVIRONMENTAL FATE AND PATHWAYS ID: 108-39-4
DATE: 24.05.2004
Result : - After 160 days and at a concentration of 39 ng/g m-cresol in soil, ca.15%
mineralization was observed.
- The percent mineralized increased slowly and linearly with time.
- For the majority of the test compounds no adaptation period was
observed.
Reliability : (3) invalid
No standard test procedure. Test design can only be used to assess
degradation in soil of the pristine aquifer of Lula, Okla.

3.3.1 TRANSPORT BETWEEN ENVIRONMENTAL COMPARTMENTS
Type : volatility
Media : water - air
Air : % (Fugacity Model Level I)
Water : % (Fugacity Model Level I)
Soil : % (Fugacity Model Level I)
Biota : % (Fugacity Model Level II/III)
Soil : % (Fugacity Model Level II/III)
Method : other: measured
Year : 1999
Method : Thermodynamic column method of Brunner et al. 1990 applied [Brunner S,
Hornung E, Santl H, Wolff E, Pringer OG, Altschuh J, Brueggemann R
(1990) Henry´s law constants for polychlorinated biphenyls: Experimental
determination and structure-property relationship. Environ Sci Technol 24,
1751 - 1754]:
- Aqueous solution of the TS produced in a generator column
- Solution is passed through gas liquid desorption column where it contacts
a gas stream and the partition equilibrium is reached
- Gas and water are separated: water flows to the receiver dosing funnel,
the gas is conducted into an absorption vessel where the TS is absorbed in
organic solvent
Result : Henry's law constant (25 degrees C):
H = 3.5 E-5 calculated to
H = 8.67 E-2 Pa.m3.mol-1
Test condition : - Temperature 25 °C
- Gas phase: Nitrogen
- Liquid phase: Demineralized, distilled water
- Analysis: GC/ECD
