Degradation of toxaphene in water during anaerobic and aerobic conditions

Lacayo, Martha LU ; van Bavel, Bert and Mattiasson, Bo LU (2004) In Environmental Pollution 130(3). p.437-443
Abstract
The degradation of technical toxaphene in water with two kinds of bioreactors operating in sequence was studied. One packed bed reactor was filled with Poraver(R) (foam glass particles) running at anaerobic conditions and one suspended carrier biofilm reactor working aerobically. Chemical oxygen demand (COD), chloride, sulphate, pH, dissolved oxygen, total toxaphene and specific toxaphene isomers were measured. After 6 weeks approx. 87% of the total toxaphene was degraded reaching 98% by week 39. The majority of the conversion took place in the anaerobic reactor. The concentrations of toxaphene isomers with more chlorine substituents decreased more rapidly than for isomers with less chlorine substituents. (C) 2004 Elsevier Ltd. All rights... (More)
