Ambient air concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans in Ohio: Sources and health risk assessment

Bioaerosols and Particle Release During Composting of Contaminated Sawmill Soil

“…Our studies support previous findings that the most toxic dioxin isomer, 2,3,7,8-TCDD, is not recovered in ambient air (Christmann et al, 1989;Edgerton et al, 1989;Hunt and Maisel, 1990;Rappe et al, 1989). Other researchers have used high-volume air samplers that collect hundreds or thousands of cubic meters of air to quartz microfiber filters (particulates) and polyurethane foam (PUF, vapor phase) (Table 4).…”

Temporal Trends and Sources of PCDDs and PCDFs in the Great Lakes: Herring Gull Egg Monitoring, 1981-1991

“…Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) are distributed worldwide (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). In the Great Lakes region, PCDDs and PCDFs have been identified in sediments (17), air (18,19), water (8), fish (20)(21)(22), reptiles (23,24), birds (20,(25)(26)(27), and mammals (28). Few studies, however, have investigated long-term temporal changes in levels of these compounds in Great Lakes biota or examined large-scale geographic differences in PCDD/PCDF contamination in biota from this region.…”

Atmospheric transport and transformation of polychlorinated dibenzo-p-dioxins and dibenzofurans

“…Comparisons between congener profiles in atmospheric samples and their possible sources have been carried out previously (3,(9)(10)(11). Both similarities and differences in congener profiles between atmospheric samples and combustion sources have been reported.…”
