Soils and sediments in the floodplain of the Tittabawassee River downstream of Midland, Michigan, USA contain elevated concentrations of polychlorinated dibenzofurans (PCDF) and polychlorinated dibenzo-p-dioxins (PCDD). As a long-lived, resident top predator, the great horned owl (Bubo virginianus; GHO) has the potential to be exposed to bioaccumulative compounds such as PCDD/DF. Site-specific ...
The concentrations of polychlorinated dibenzo-p-concentrations dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) (PCDD/Fs), and polychlorinated biphenyls (PCBs) were determined in fruit and vegetables collected in farms located in the well-known "Land of Fires" area of Southern Italy, in an effort to learn more about the environmental pollution of this high-risk area due to illegal waste d...
BACKGROUND Risk assessment of human environmental exposure to polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDFs) and other dioxin-like compounds is complicated by several factors, including limitations in measuring intakes because of the low concentrations of these compounds in foods and the environment and interspecies differences in pharmacokinetics and responses. OBJECTIVES W...
Polychlorinated dibenzo‐p‐dioxins, polychlorinated dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) are environmental contaminants regulated by the Stockholm Convention of Persistent Organic Pollutants. Being hydrophobic and lipophilic, these compounds accumulate in the marine environment in sediments and lipid‐rich tissue of marine organisms, making these matr...

To assess levels of chlorinated contaminants in breast milk, we measured organochlorine pesticides, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) in breast milk samples collected in 1994 according to the World Health Organization protocol from 92 donors that were representative of regional populations in southern Kazakstan. High ...
Dioxin-like PCBs represent an important component of the Sigma-TEQ in many environmental media. Specifically, in animal produce and in fish PCBs dominate the Sigma-TEQ ingested by humans. This in turn leads to high background body burdens in humans with PCB-TEQ greater than that associated with PCDD/Fs. High fish consumers are apparently subject to elevated TEQ exposure from dioxin-like PCBs. T...
The distribution and time trend of organochlorine pesticide (OCP), polychlorinated biphenyl (PCB), and polychlorinated dibenzo-p-dioxin/polychlorinated dibenzofuran (PCDD/PCDF) concentrations in human milk samples from Croatia collected in 1981-2003 are presented. Between 1981/1982 and 1987/1989, the concentrations of HCB, beta-HCH, DDE, and total PCBs decreased about 50%, while for the last de...
During the past decade a considerable amount of data has been generated concerning polychlorinated dibenzodioxin (PCDD) and polychlorinated dibenzofuran (PCDF) levels in humans from many geographical locations. To organize these data in a useful fashion for environmental purposes and for consideration of human toxicity, selected portions of our data are presented in a somewhat atypical fashion,...
