Extraction and Identification of Endrin and Heptachlor Degradation Products

Abstract

Abstract Two endrin degradation products and a heptachlor degradation product, in addition to heptachlor epoxide, were extracted from soybean plants grown in soil treated with 14C-endrin or 14C-heptachlor. One endrin product was identified as 1,8,9,9,10,11-hexachloropentacyclo[6.3.0.12,5.03′7.06,10]dodecan-12-one (endrin delta ketone); the second endrin product was identified as 1,8,9,9,10,11-hexachlorohexacyclo-[6.3.0.12′5.03,7.06,10.011,12]dodecan-12-ol (endrin alcohol); and the heptachlor product was identified as l,7,8,9,10,10-hexachloro-2,3-6,5-endo-tricyclo[5.2.1.02′6]deca-4,8-diene-exo-3-ol (hydroxychlordene). Identifications were by multiple GLC and TLC techniques.
