Results and discussion
Any other information on results incl. tables
RS-Freetext:
I. About 19 % (range 4 - 29 %) of the applied dose was excreted as mercapturic acid in urine within 24 hrs.
II. The maximum rate for excretion of mercapturic acid via urine 2 - 6 days after dosing with 1300 or 1820 µmole/kg bw was
given with 10 or 21 µmole/kg bw/h.
Applicant's summary and conclusion
- Executive summary:
1,2 -dichloro-4-nitrobenzene is excreted mainly via urine in the form of mercapturic acid derivate N-acetyl-S-(2 -chloro-4-nitrophenyl)-L-cysteine (UNEP 2005).
