enhanced microbial degradation of toxaphene by natural microorganisms occurred in soil and sediment amended with organic matter kept under anaerobic (flooded) conditions. laboratory experiments yielded a dissipation half-life of approximately 3 and 1 week for soil and sediment, respectively, containing 10 ppm of technical toxaphene and a 1 alfalfa meal amendment. enhanced anaerobic dissipation also took place in soil containing 500 ppm of toxaphene, although at a lesser rate than at 10 ppm, and when cotton gin waste was used as amendment in place of alfalfa meal. sediment in a toxaphene-contaminated pesticide waste disposal ditch was amended with 10 steer manure and flooded to ascertain field utility of the technique for on-site decontamination, and these results are also discussed.
