Chimney deposits from wood burning exhibit a homologue profile for the 135 chlorodibenzofurans (Cl sub(x)DF) (x = 1-8) and the 75 chlorodibenzodioxins (Cl sub(x)DD) (x = 1-8) close to that from flue gas from municipal waste incineration. The Cl sub(x)DF dominate the Cl sub(x)DD by the factor of 5-10 as do the lower chlorinated Cl sub(x)DD/Cl sub(x)DF (x = 1-3) over the higher chlorinated (x = 4-8). The content of Cl sub(x)DD/Cl sub(x)DF (x = 4-8) in soot from wood burning was for the sum of chloro isomers in nanograms per kilogram in the range of 70-13,400 (Cl sub(8)DF/Cl sub(4)DF) for the chlorodibenzofurans and 90-3900 (Cl sub(8)DD/Cl sub(4)DD) for the chlorodibenzodioxins.
