They are known to be distributed as contaminants of commercial products and as by-products from com- bustion processes. A considerable volume of info

Dioxins as Contaminants of Herbicides: The U.S. Perspectiveand its dioxin contaminant, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) during the Vietnam Conflict. The basis for resolving the Agent Orange controversy must in large measure stem from the results of scientific inquiry.

Methodology and Preliminary Results for the Isomer-Specific Determination of TCDDs and Higher Chloriwith natural wood obtained from areas where contamination from pesticides and herbicides was expected to be minimal. The development and application of appropriate analytical methodology have provided preliminary evidence that significant concentrations of CDDs are produced under these circumstances.

Analytical Methodology for the Determination of PCDDs and PCDFs in Products and Environmental Samplec isomer in a particular isomer group from all of its isomers and other congeners has advanced from the ability to separate 2,3,7,8-TCDD from only two of its isomers in 1974 to an ability to separate all of the 22 TCDD isomers in 1978. Likewise all 10 isomers of HP.CDD have been separated as have the two isomers of H.CDD.

Changes in Dioxin Isomer Group Ratios in the Environment: An Update and Extension of the Present TheA recent study of dioxins produced by wood burning stoves now makes it possible to further test this theory as well as to compare the dioxin isomer group ratios observed in different types of combustion units.
