Abstract

Abstract Polychlorodibenzo-p-dioxin (PCDD) isomers are found in many environmental samples in proportions that are numerically consistent with values predicted by a steady state kinetic model of a red-ox reaction system. Recent data extend the geographical significance of these findings to include regions of the Western United States. In addition, extension of the red-ox hypothesis, is proposed to explain similarities and differences in the behavior of PCDDs from unrelated combustion sources, which includes the possible role of photo-initiated red-ox mechanisms in the removal of PCDDs from the environment.
