Obsah PCDD/F je v těchto oblastech až 10 x vyšší než u ryb z jižní polokoule a Tichomoří. 2,3,7,8 tetrachlordibenzo-p-dioxin a 2,3,4,7,8 pentachlordibenzofuran jsou klasifikovány jako prokázané karcinogeny pro lidi (kategorie 1) PCDD /Fs and PCBs are stable chemicals that require temperatures far in excess of those encountered in cooking for their destruction. Decreases in concentration in meat during cooking have been observed. Thus in one study, pan-frying hamburger patties were found to reduce the amount of PCDD/Fs actually consumed by 40-50% if the pan fats and. Polychlorinated dibenzofurans ( PCDF s) are a family of organic compounds with one or several of the hydrogens in the dibenzofuran structure replaced by chlorines. For example, 2,3,7,8-tetrachlorodibenzofuran (TCDF) has chlorine atoms substituted for each of the hydrogens on the number 2, 3, 7, and 8 carbons (see structure in the upper left.
