Materials and methods

Principles of method if other than guideline:
- 14C-labeled 1,2,4-trichlorobenzene was added to a soil-water-suspension
- after 5 days the test was finished and samples were taken by different chemical treatments (e.g. volatile organic compounds and CO2 in the headspace, determination of test substance and 14CO2 in aqueous phase)
GLP compliance:
not specified
