PCDDs, PCDFs and Coplanar PCBs in Fish and Shellfish from Coastal Area of Bohai Sea, China

Biodegradation of PCDDs/PCDFs and PCBs

As a consequence of the rapid development of modern society during the 20th century, a significant amount of organic chemicals has been dispersed into the environment. Many of them have been used as pesticides, insecticides, defoliants and industrial chemicals or produced as undesirable industrial by-products. A large amount of them show several metabolic and toxic activities including mutageni...

Polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and biphenyls (PCBs)

PCDDs, PCDFs, and PCBs in human blood in relation to consumption of crabs from a contaminated Fjord area in Norway.

Consumption of fish and shellfish from contaminated areas may be an important source of human exposure to persistent organohalogen compounds such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs). We determined concentrations of 2,3,7,8-substituted PCDDs and PCDFs and 19 PCB congeners in whole blood samples from three group...

CONCENTRATIONS OF PCDDs, PCDFs AND PCBs IN SAMPLES OF BUTTER FROM 24 COUNTRIES

Introduction Residues of PCDD/Fs and PCBs present in butter may indicate the occurrence of these contaminants in pastureland on which cattle graze, and thus provide a useful environmental indicator of fluxes to pastures. These would have principally an atmospheric component although there are also other possible sources of contamination to pastures such as a water-based contribution from irriga...

Statistical comparison of residential soil concentrations of PCDDs, PCDFs, and PCBs from two communities in Michigan.

The University of Michigan dioxin exposure study was undertaken to address concerns that the industrial discharge of dioxin-like compounds in the Midland, MI area had resulted in contamination of soils in the Tittabawassee River floodplain and downwind of the incinerator. The study was designed in a rigorously statistical manner comprising soil measurements of 29 polychlorinated dibenzo-p-dioxi...
