A Lakeland sandy loam was treated at three depths with 14 Cendrin insecticide in which one crop of soybeans (Glycine max L., Merr.) was grown. After harvesting the soybeans, the soil was sectioned and assayed for endrin residues. At least three and possibly five transformation products of endrin occurred. Two products were identified as 1,8,9,9,10,11‐hexachloropentacyclo [6.3.0.1 2,5 .0 3,7 .0 6,10 ] dodecan‐12‐one (endrin delta ketone) and 1,8,9,9,10, 11‐hexachlorohexacyclo [6.3.0.1 2,5 .0 3,7 .0 6,10 .0 11,12 ] dodecan‐12‐ol (endrin alcohol). A third product may have been 1,8,9,9,10,11‐hexachloropentacyclo [6.3.0.0 2,11 .0 3,7 .0 6,10 ] undecan‐12‐carboxaldehyde (endrin aldehyde). Endrin transformation appeared to increase with soil depth. In an extremely acid soil (pH 4.2) endrin transformed to some endrin ketone and probably endrin aldehyde during treatment of the dry soil, but not of moist soil. Acid or base treatment of endrin and several endrin isomers indicated that endrin was stable under basic conditions and that endrin alcohol and endrin aldehyde (presumably) were stable in all treatments tested, except the base treatment at 100C for endrin aldehyde.
