DIOXINS - PRIMER AND COMMENTARY --
One of the most feared set of compounds are the polychlorinated
dibenzodioxins and polychlorinated dibenzofurans (PCDDs and PCDFs),
frequently shortened to "dioxins and furans" or merely "dioxins".
Rarely does anyone in the media explain what PCDDs or PCDFs are, let
alone the toxic equivalency factor (TEF) assigned to each. One would
think such important information, needed to understand the risk of
"dioxin" emissions, would be carefully and frequently communicated.
Sadly, it is not. A polychlorinated dibenzodioxin is
two benzene rings joined together by two oxygen atoms. A
polychlorinated dibenzo-furan is similar but has only one oxygen
GLOSSARY OF TECHNICAL TERMS -- Adsorb To collect (a gas, etc.) in condensed form on a surface. Aliquot
An analytical chemistry term referring to a measured portion taken from
a solution. When an aliquot of a sample solution is
analyzed, the concentration of the targeted compound in the original
solution can be calculated from those analysis results. Analyte The targeted compound or element for which an analysis is being executed. MORE
