General Description
Chloro dibenzo-p-dioxins (CDPDs) are solid crystalline in nature and probably exist as adsorbed to particulate materials and are mainly produced as a function of combustion of organic compounds. There is no known use for these chemicals. Other than for research purposes, they are not deliberately produced by industry. Most CDPDs are produced in small amounts as undesirable by-products of certain processes, such as manufacturing other chemicals or bleaching at paper and pulp mills. The most "infamous" CDPD contamination and poisoning occurred during the Vietnam War as a by-product of the production and use of Agent Orange. CDPDs can also be released from incinerators. Certain isomers are known human carcinogens.
