This report explains how USAFOEHL determined ambient levels of polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and PCBs at Arnold AFS. The PCDDs and PCDFs of interest included 2,3,7,8-tetrachlorodibenzodioxin (TCDD) and 2,3,7,8-tetrachlorodibenzofuran (TCDF) as well as tetra through octa chlorinated congener classes of dioxins and furans. 收起
