Distribution and elimination of a single polychlorinated biphenyl isomer (2,5,2′,5′-tetrachloro[14C]biphenyl, 4-CB) were compared in a nonfatty fish (yellow perch) and a fatty fish (rainbow trout).

Adult fish were exposed acutely to 4-CB ( μg/fish) by the oral or intraperitoneal route and were killed at designated times thereafter for one by: A polychlorinated biphenyl (PCB) is an organic chlorine compound with the formula C 12 H 10−x Cl lorinated biphenyls were once widely deployed as dielectric and coolant fluids in electrical apparatus, carbonless copy paper and in heat transfer fluids.

Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the s Chemical formula: C₁₂H10−xClₓ. To address these issues, juvenile rainbow trout (Oncorhynchus mykiss) were exposed to dietary concentrations of three Aroclor® mixtures (,) in food for 30 d followed by an additional d of nonspiked food at 8°C.

Accumulation, depuration, and potential biotransformation of 92 PCB congeners were by: Bioaccumulation describes the accumulation and enrichment of contaminants in organisms, relative to that in the environment.

Bioaccumulation is the net result of all uptake and loss processes, such as respiratory and dietary uptake, and loss by egestion, passive diffusion, metabolism, transfer to offspring and growth (Figure 1).Bioaccumulation thereby comprises the more specific processes of.

The objective of this study is to determine the concentrations of polychlorinated biphenyls (PCBs) in different fish species collected from fish outlets in the south Indian city of Hyderabad.

The samples of fish extracted by using Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) and concentrations of polychlorinated biphenyls (PCBs, 45 congeners) were determined by gas Cited by: 5. Polychlorinated Biphenyls (PCBs) Polychlorinated biphenyls (PCBs) are manufactured organic chemicals that are no longer produced in the United States, but are still in the environment and can cause health problems.

PCBs do not easily break down and may remain. Dietary effects of polychlorinated biphenyls on mink. Platonow NS, Karstad LH.

CRITERION DOCUMENT POLYCHLORINATED BIPHENYLS Criteria Aquatic Life For polychlorinated biphenyls the criterion to protect i freshwater aquatic life as derived using the Guidelines is jug/1 as a hour average and the concentration should not exceed ;ug/l at any time.

This chapter provides an overview of PCBs in the environment as a background to understanding their history of use, sources of input to the environment, distribution in the environment, and their human health and ecological e PCBs are such complex chemicals, knowledge of their chemical and physical properties is needed to understand their transport, fate, and toxicity.

POLYCHLORINATED BIPHENYLS (PCBs) What are they. PCBs are human-made chemicals of varying toxicity. Because they are good insulators and are nonflammable, PCBs have been widely used as coolants and lubricants in transformers and other electrical equipment. Evidence that PCBs damage the environment and may cause health hazards led to the end of PCB.

Dividing this value by the geometric mean (45,) of whole-body BCF values for salmonids (rainbow trout, 46,; brook trout. 42, ) gives a residual value for freshwater of wg/l. The mean BCF of 45, for salmonids is based only on laboratory data.

When manufacturer-recommended doses were applied to the observed levels, the estimated upper bound human exposure to dioxins and dioxin-like PCBs from dietary intake of these products ranged from to pg WHO-TEQ kg-1 body weight day-1 for adults and from to 10 pg WHO-TEQ kg-1 body weight day-1 for by: tion of polychlorinated biphenyls by juvenile Baltic salmon (Salmo salar L.) after oral gavage exposure.

The dietary uptake of 12 halogenated diaromatic compounds was studied using northern pike (Esox lucius L.) fed with rainbow trout (Oncorhynchus mykiss (Walbaum)).Before the trout were fed to the pike, they had been injected with a cocktail of five polychlorinated biphenyls, four polychlorinated naphthalenes, and three polybrominated diphenyl ethers, dissolved in rainbow trout by: Polychlorinated biphenyls, in short PCBs, are a group of man-made chemicals.

PCBs have been used in many different products, including electrical equipment, surface coatings, inks, adhesives, flame-retardants, and may be released into the environment, for instance when waste that contains PCBs is incinerated or stored in landfills.

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.

degree of protection, although concentrations as low as ug/l resulted in measurable accumulation by various species of filter-feeding shellfish. Among sensitive species of teleosts, total PCB residues (in ug/kg fresh weight) in excess of in diets, in whole body.

The following table shows disposal approvals issued under the Toxic Substances Control Act (TSCA) to accept and/or dispose of PCB waste. These facilities are either permitted by EPA to dispose of PCB waste or may handle or dispose of certain types of PCB waste outside of a permit in accordance with the regulations outlined in Title 40 of the Code of Federal Regulations in part Polychlorinated biphenyls (PCBs) are a class of persistent, bioaccumulative, and toxic (PBT) compounds that historically had a wide range of uses, including consumer products.

PCBs are created by reacting biphenyl with chlorine (Pomerantz, ). PCBs were used in:. Polychlorinated biphenyls (PCBs) are a group of chemicals that contain individual compounds (known Epidemiological studies indicate an association between dietary PCB exposures and developmental effects.

PCBs (Polychlorinated Biphenyls) are notoriously hazardous chemicals produced commercially since They have now infiltrated our food chain. PCBs are a member of the POPs (persistent organic pollutants) family.

They are commonly known as synthetic chlorinated hydrocarbon compounds and chances are they may just be on your dinner plate. Polychlorinated biphenyls (containing 60 or more percent chlorine by molecular weight) listed separately.

Public Notices Related to this Chemical. Withdrawal of Rulemaking - Polychlorinated Biphenyls (Food Chain Exposures). It has long been known that polychlorinated biphenyls (PCBs) are inadvertently generated during manufacture of some pigments.

This has become more of an issue in Washington State because of allowances of up to 50 ppm PCBs in most products under the federal Toxics Substances Control Act (TSCA) and much lower allowances for PCBs in waterways.

For example, a single gram fillet of farmed rainbow trout has a gram of omega-3, g of omega-6, % of the B12 RDA, and a decent amount of selenium.

The same amount of wild trout is extremely similar nutritionally, with the main changes being mg fewer omega-3s and mg fewer omega-6s. Lake trout (Salvelinus namaycush) were fed bloater (Coregonus hoyi) in eight laboratory tanks over a d experiment. At the start of the experiment, four to nine fish in each tank were sacrificed, and the concentrations of 75 polychlorinated biphenyl (PCB) congeners within these fish were determined.

Polychlorinated biphenyl congener concentrations were also determined in the 10 lake trout. Aroclora highly chlorinated technical PCB mixture composed of primarily hexa- through decachlorobiphenyls, was used to lubricate high voltage process equipment at a chlor-alkali facility in coastal southeastern Georgia.

Disposal of process wastes has resulted in extensive contamination of environmental media at the nearby intertidal marsh. Dietary accumulation of 23 hydrophobic organochlorines (OCs) by juvenile rainbow trout (Oncorhynchus mykiss) was studied with the objective of obtaining relationships between bioaccumulation parameters and the octanol/water partition coefficient (K{sub ow}).

Polychlorinated biphenyl (PCB), any of a class of organohalogen compounds prepared by the reaction of chlorine with biphenyl.A typical mixture of PCBs may contain over compounds and is a colourless, viscous mixture is relatively insoluble in water, is stable at high temperatures, and is a good dielectric (electrical insulator).

Because of these qualities, PCBs are particularly.
