A study was conducted examining serum levels of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) in pulp and paper mill workers. Sera were analyzed from workers from a pulp and paper mill in which a previous evaluation had identified PCDDs and PCDFs in air and surface samples.

Robert W. Coppock, P.N. Nation, in Veterinary Toxicology, Chlorinated dioxins. Aquaculture animals are a source of polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyl (PCBs) compounds. Each of these groups is a mixture of congeners.

These groups of compounds are collectively referred to as persistent organic carbons (POCs). Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are common contaminants at historical contaminated sites.

PCDD/Fs are generally referred to as “dioxins” although the name is technically incorrect, it has been used so much that it has stuck. Polybrominated dibenzo-p-dioxins (PBDDs) and dibenzofurans (PBDFs) occur as trace (ppb) contaminants in brominated flame retardants and are produced during combustion of these chemicals.

They are also formed when organics are incinerated in the presence of bromine, e.g., in municipal and industrial incinerators and in internal-combustion by: Polychlorinated biphenyls (PCBs), polybrominated biphenyls, polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzofurans belong to a group of compounds that are structurally related and are environmentally and biologically persistent.

These chemicals are ubiquitous and detectable in a variety of environmental media and biota.

In this study, 19 water samples from the middle reaches of the Yangtze River were analysed for the levels of PCDD/Fs and dioxin-like PCBs (dl-PCBs).Cited by: 5.

ABSTRACT. Polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofuranes (PCDF) and polychlorinated biphenyls (PCB) are types of persistent and bioaccumulating organic pollutants with enhanced chronic toxicity and carcinogenic properties and can be considered as environmental indicators of anthropogenic activities since their occurrence in the environment can always be linked to anthropogenic.

Chapter Polychlorinated dibenzodioxins and dibenzofurans General description Physical and chemical properties The polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are two series of almost planar tricyclic aromatic compounds with very similar chemical properties.

The general structures are given in Fig. Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) —compounds that contain from 1 to 8 chlorine atoms, resulting in a total of 75 PCDDs and PCDFs.

Polychlorinated dibenzofurans (PCDFs) are a family of organic compounds with one or several of the hydrogens in the dibenzofuran structure replaced by chlorines.

For example, 2,3,7,8-tetrachlorodibenzofuran (TCDF) has chlorine atoms substituted for each of the hydrogens on the number 2, 3, 7, and 8 carbons (see structure in the upper left. CDDs are a family of 75 chemically related compounds commonly known as chlorinated dioxins.

One of these compounds is called 2,3,7,8-TCDD. It is one of the most toxic of the CDDs and is the one most studied. In the pure form, CDDs are crystals or colorless solids.

CDDs enter the environment as mixtures containing a number of individual components. 2,3,7,8-TCDD is odorless. Get this from a library. Polychlorinated dibenzo-p-dioxins: criteria for their effects on man and his environment.
