General Description
Chlorodibenzofurans (CDF) 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 CDFs are produced in small amounts as undesirable by-products of certain processes, such as manufacturing other chemicals or bleaching at paper and pulp mills. CDFs can also be released from incinerators. CDFs have known mutagenic activity.
