When cattle dips were imitated in the laboratory by combining soil, 
feces, urine, and extracts of scrapings from cattle hides, the y-isomer 
was lost much more rapidly than other isomers. 
Using the bacteria 
Clostridium sporogenes or Bacillus coli found in such mixtures, BHC 
gave rise to traces of benzene in seven days as well as monochlorobenzene 
and 1,2,3,5-tetrachlorobenzene (Allan, 1955). 
decoloratus, gave rise to S-(2,4-dichlorophenyl)glutathione (Clark et al 
1966).
