“…This suggests that the PCDD profile in Figure A could have originated from PCP production and atmospheric emissions at WGK, and later photolysis. It is also possible that OCDD dominated profile resulted in part from PCB incineration at WGK; Brenner et al show dominance of OCDD among PCDD in crude exhaust from PCB incineration. Various scenarios may hold the truth to the homologue pattern we are seeing in Sauget tree bark.…”

Polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF) are ubiquitous urban/industrial contaminants found in tree bark, which acts as a long-term passive atmospheric sampler. Twenty seven bark samples (tree age 8–92 years) were collected from residential and industrial areas near Sauget, IL to identify the trends of 2,3,7,8-Cl PCDD & PCDF congener distributions, toxic equivalents (TEQ), and PCDD & PCDF homologue distributions. The Sauget area is heavily industrialized, with a long history of chlorine production, and is the largest single contributor to air pollution exposure risk in St. Louis. Analysis of seven 2,3,7,8 Cl-substituted PCDD and 10 PCDF congeners showed ∑PCDD7 ranging from 2214 to 71821 pg g(–1) lipid and ∑PCDF10 from 355 to 13707 pg g(–1) lipid, the highest in trees <20 years old in both cases. OctaCCD and octaCDF respectively dominated ∑PCDD7 (89% average) and ∑PCDF10 (57% average). The 2,3,7,8-Cl congener profiles showed slight differences among samples showing that all were affected by similar sources but at different magnitudes. ∑TEQ ranged from 35 to 624 pg g(–1) lipid, dominated by 1,2,3,7,8-PeCDD (average = 41.3% of total TEQ). Tetra-Cl through hepta-Cl homologues were dominated by non-2,3,7,8-Cl compounds for both CDD and CDF. Homologue profiles for 26 samples had a “sink” profile dominated by octaCDD, whereas one sample showed effects of a local source.
