Dietary exposure levels to polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and non-ortho-polychlorinated biphenyls in U.S. meat, poultry, and siluriform fish from 2018-2019
Daily dietary exposure estimates from beef, pork, chicken, turkey, and siluriform fish were calculated using toxic equivalency (TEQ) data from the U.S. Department of Agriculture’s survey of dioxins and dioxin like compounds (DLCs) in the domestic meat supply and consumption data. Exposure estimates ...

Survey of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and non-ortho-polychlorinated in U.S. beef livers and comparison to paired fat samples
Introduction: The U.S. Department of Agriculture (USDA) conducted a survey of domestic beef liver to determine the residue levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and nonortho-polychlorinated biphenyls (no-PCBs) in commercial beef liver and to do a...

Survey of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and non-ortho-polychlorinated biphenyls in U.S. meat and poultry from 2018-2019: Toxic equivalency levels, temporal trends, and implications
The U.S. Department of Agriculture (USDA) conducted a statistically-based survey of the domestic meat supply (beef, pork, chicken, turkey, dairy cow, and catfish) to determine the current residue levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and non-orth...

Levels and trends of dioxins, dioxin-like compounds, and PBDEs in the U.S. domestic meat supply, mid-1990s to 2019
The US Department of Agriculture (USDA) has conducted a survey of dioxin and dioxin-like compound (PCDDs, PCDFs, and PCBs) residues in the domestic meat supply every 5 years since the mid-1990s (mid- 90s, 2002-03, 2007-08, 2012-13). An additional survey is currently being conducted for 2018-19. Surv...

Facile synthesis of bromo- and mixed bromo/chloro dibenzo-p-dioxins and [14C]-labeled 1,3,7,8-tetrabromodibenzo-p-dioxin
Polybrominated dibenzo-p-dioxins (PBDDs) and mixed bromo/chloro dibenzo-p-dioxins (PXDDs) are persistent organic pollutants that can possess the same toxicity as their fully chlorinated analogs (PCDDs) and have been identified in the same matrices. The development of a general synthetic method was ...

Synthesis of polybrominated dibenzo-p-dioxins and mixed bromo/chloro dibenzo-p-dioxins
Polychlorinated dibenzodioxins (PCDDs) are considered to be persistent organic pollutants and their adverse health effects are intensively documented. Polybrominated (PBDD) and mixed bromo/chloro dibenzo-p-dioxins (PXDD) by-products are formed during brominated flame retardant (BFR) synthesis and d...

The genomic landscape of rapid, repeated evolutionary rescue from toxic pollution in wild fish
Several populations of Atlantic killifish (Fundulus heteroclitus) in contaminated Atlantic coast estuaries have evolved resistance to the toxic effects of PCBs, dioxins, and PAHs. However, the genetic mechanisms of resistance and whether they are shared among populations is not known. We sequenced t...

Survey of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and non-orthopolychlorinated biphenyls in U.S. meat and poultry from 2012-2013: Toxic equivalency levels, patterns, temporal trends, and implication
The U.S. Department of Agriculture (USDA) conducts a statistically-based survey of the domestic meat supply (beef, pork, chicken, and turkey) to determine current levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and non-ortho-polychlorinated biphenyls (no-P...

Dioxins, dioxin-like compounds, and PBDEs in the U.S. domestic meat supply: trends and levels 2003 to 2013
In the mid-1990s, 2002-2003, 2007-2008, and again in 2012-2013 the U.S. Department of Agriculture (USDA) conducted statistical surveys for dioxin and dioxin-like compound (PCDDs, PCDFs, and PCBs) residues in domestic meat and poultry. The surveys were conducted to determine background levels of diox...

Dioxin, furan, PCB, and PBDE levels in U.S. foods: Survey trends and consumer exposure
The U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) and Food Safety and Inspection Service (USDA-FSIS) have conducted statistical surveys for dioxins (PCDDs, PCDFs, and PCBs) and polybrominated diphenyl ethers every 5 years since the mid-1990s (mid-1990s, 2002-3, 2007-8). I...
