7 Experiments with plants were inconclusive but the data indicated 
pentachlorocyclohexene as a metabolite (132, 1264). In soil, lindane 
broke down rapidly to a non-toxic compound (164, 869) which was identi- 
fied as y-pentachlorocyclohexene (1534). Some CO, was also formed from 
y-BHC in submerged soils (919). 
When exposed to ultra-violet irradiation (2537 A), o=,f8-,y-, and 
6-BHC did not yield any products (1228). 

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 (17). 
| The cattle tick, Boophilus decoloratus, gave rise to S-(2,4-dichloropheny1) 
glutathione (280).

cl4 labeled a-BHC was used to study the effect of heating at baking 
temperatures in flour. About 90% of residual activity was 1,2,4-tri- 
chlorobenzene. Small amounts of 1,2,3- and 1,3,5-trichlorobenzene, the 
three dichlorobenzenes, chlorobenzene and possible benzene were also 
present (178). 

In sea water, the gamma isomer apparently ''decayed" more rapidly 
' than the alpha or beta isomers. No breakdown products were identified (1601).
