Hexachlorobenzene was dechlorinated to tri- and dichlorobenzenes in anaerobic sewage sludge. The complete biotransformation of 190 microM hexachlorobenzene (approximately 50 ppm) occurred within 3 weeks. The calculated rate of hexachlorobenzene dechlorination was 13.6 mumol liter-1 day-1. Hexachlorobenzene was dechlorinated via

The aim of the study was to induce and enhance the degradation of hexachlorobenzene (HCB), a highly-chlorinated persistent organic pollutant, in two ecologically different tropical soils: a paddy soil (PS) and a non-paddy soil (FS). The degradation of HCB was

Decomposition of hexachlorobenzene (HCB) on high surface area y-alumina was comprehensively studied using in situ Fourier transform infrared spectroscopy, gas chromatography/mass spectrometry (GC-MS) and ion chromatography. Monitoring of the temperature-dependent decomposition by Fourier transform infrared spectroscopy showed that HCB decomposed
