Abstract
The transformation kinetics of halogen substituted benzenes was examin ed in estuarine sediment. The sediment was sulfidogenic with sulfate c oncentration of 20 mmole/l. All compounds transformed without any lag period, with rate constants between 0.0016 and 0.0342 day(-1) or half- lives of 20 and 433 days. For the compounds with different halogen sub stituents on the aromatic ring, the transformation rate of the compoun d decreased in the order: I>Br>Cl>F.
