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...

Many of them have been used as pesticides, insecticides, defoliants and industrial chemicals or produced as undesirable industrial by-products.

متن کامل[Time serial changes in the concentrations of the etiological agents of fetal Yusho--PCDDs and PCDFs].
We determined polychlorinated dibenzofurans (PCDFs) and polychlorinated dibenzo-p-dioxins (PCDDs) in 6 preserved umbilical cords of fetal Yusho patients and in 11 preserved umbilical cords of Yusho suspected persons who were born to mothers with Yusho from 1970 to 2002, which were Yusho group. As a control, we also analyzed PCDFs and PCDDs in 15 preserved umbilical cords of babies who were born...
متن کاملCONCENTRATIONS 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...
