Systematic Studies on the Breakdown of p,p’-DDT in Tobacco Smokes: III. Isolation and Identification of the Non-Volatile Degradation Products of p,p’-DDT in p,p’-DDT-Treated Tobacco Smokes

This paper describes the methods used in smoking p,p'-DDT-treated tobacco, collecting the smoke condensate, chromatographing the condensate on activated Florisil and deactivated alumina columns, and finally identifying the non-volatile p,p'-DDT pyrolysis products in the tobacco smoke condensate. The pyrolysis products identified were: p,p'-DDT, p,p'- DDE, p,p'-TDE, p,p'-DDM, trans-p,p'-dichlorostilbene, bis-(p-chlorophenyI)methane, and p,p'-dichlorobenzophenone.
