Estimation of Daily Intake of PCDDs, PCDFs and Co-PCBs from Baby Foods

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...

Human intake of PCDDs, PCDFs, and dioxin like PCBs in Japan, 2001 and 2002.

PCDDs, PCDFs, and dioxin like PCBs (dioxin) surveillance results derived from regular environmental monitoring as well as other dioxin surveys by national and local governmental bodies in Japan were collected and analyzed. Several thousand data for air and soil in fiscal year 2001 (from 01/04/2001 to 31/03/2002) and 2002, water (from the sea, rivers and lakes), sediment (from the sea, rivers an...

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

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...
