Composition of chlorinated dibenzodioxins and dibenzofurans in various samples.
The composition of chlorinated dibenzodioxins (CDD) and dibenzofurans (CDF) in terms of the degree of chlorination (tetra- to octachloro-) is displayed by principal components projection. Chlorinated dibenzodioxins and dibenzofurans with 4-6 chlorines are the main classes in samples of crabs and lobsters, CCD with 7 and 8 chlorines prevail in human samples. Chlorinated dibenzodioxins and dibenzofurans from incinerator ash are similar to those from human tissues. Those from gaseous incinerator emissions are enriched in less chlorinated classes and resemble residues isolated from conifer needles. Compositions of CDD and CDF in ambient air vary depending on both local and remote sources.
