Abstract
The transformation kinetics of halogen substituted benzenes was examined in estuarine sediment. The sediment was sulfidogenic with sulfate concentration 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 substituents on the aromatic ring, the transformation rate of the compound decreased in the order: I s> Br s> Cl s> F.
