| Applications | Uses: Exposure to PCBs can occur: 1) from eating contaminated fish, 2) while repairing or maintaining old electrical transformers containing PCBs, and 3) after leakage from old fluorescent lighting fixtures and old appliances such as televisions or refrigerators. [ATSDR ToxFAQs] Also exposed are firefighters of capacitor and transformer fires. [ATSDR Case Studies, PCB Toxicity] Used in elastic polysulfide sealants in prefabricated houses built in Finland between 1959 and 1975, and workers removing sealants may be exposed, [Reference #2], Production of PCBs in the U.S. was banned in 1977., Firefighting [Category: Other], Eating fish that lived in contaminated water [Category: Food & Drugs], Formerly used in hydraulic fluid, rubber plasticizers, synthetic resin plasticizers, adhesives, wax extenders, dedusting agents, inks, cutting oils, pesticide extenders, sealants and caulking compounds, In routine screening program for in vitro assays, S-9 fractions are generally prepared from the livers of male rats which have been treated with nonspecific enzyme inducers such as phenobarbital or Aroclor 1254., Although the production and sales was discontinued in late 1977, it, may be, still present in transformers now in use., Summary of former end uses for various Aroclors:, Table: Aroclor [Table#5911], PCBs were used as coolants and lubricants in transformers, capacitors, and other electrical devices (such as fluorescent lights and refridgerators) produced before 1977. PCBs may contaminate the air and water near hazardous waste sites. In addition, PCBs bioaccumulate in the environment and may be found in fish, meat, and dairy products. (L4), Use Classification: Chemical Classes -> Dioxins, Furans, PCBs (contain phenyl rings of carbon atoms), Pesticides (chemicals used for killing pests, such as rodents, insects, or plants), Methods of Manufacturing: PCBs, were, ... prepared industrially by the chlorination of biphenyl with anhydrous chlorine in the presence of a catalyst such as iron filings or ferric chloride. The products are complex mixtures of chlorobiphenyls, whose degree of chlorination depends principally on the time of contact (12-36 hr) of the biphenyl with anhydrous chlorine. The crude product is blown with air, and a small amount of lime is added to remove hydrogen chloride and ferric chloride. The resulting chlorinated mixtures are batch-distilled to remove color and traces of hydrogen chloride and ferric chloride., Polychlorinated biphenyls, The approximate distribution of chlorinated biphenyls in Aroclor 1254 is: <0.1% di-, 1.8% tri-, 17.1% tetra-, 49.3% penta-, 27.8% hexa-, 3.9% hepta-, <0.05% octa-, and <0.05% nonachlorobiphenyl., Impurities: Chlorinated dibenzofurans, tetra-, penta-, and hexa-PDCFs, were identified in all Aroclor preparations, 1248, 1254, 1260, except Aroclor 1016, at levels from 0.8 to 2 ppm, Polychlorinated napthalenes have also been identified in Aroclor 1254., The PCDF levels are (in ppm): Cl3, 0.063, Cl4, 0.1-0.2, Cl5, 0.2-0.4, Cl6, 0.9-1.4, Cl7, 0.96., Toxic PCDF levels in ppm: 2, 3, 7, 8-Cl4, 0.053, 1, 2, 4, 8-, 8, - TCDF, 0.9, 8-PECDF, 0.49, 9-, 8-HXCDF, 2.5, 6, 8-TCDF, 0.13., Analysis of the technical PCB, Aroclor 1254 revealed the presence of a series of brominated contaminants., Formulations, Preparations: Composition: tetrachlorobiphenyls 11%, pentachlorobiphenyls 49%, hexachlorobiphenyls 34%, and heptachlorobiphenyls 6%., PCB congener composition in wt %: <0.1%, biphenyl, Cl1, <0.1, Cl2, 0.5, Cl3, 21, 48, 23, 6., Average number of chlorine atoms = 4.96, Consumption Patterns: Domestic sales in millions of pounds of Monsanto's Aroclor 1254 in the United States from 1957 to 1970 are as follows: 4.5 (1957), 6.7 (1958), 6.8 (1959), 6.1 (1960), 6.3 (1961), 6.3 (1962), 5.9 (1963), 6.3 (1964), 7.7 (1965), 7.0 (1966), 6.7 (1967), 8.9 (1968), 9.8 (1969), 12.4 (1970)., Total USA sales in 1970 amounted to 33.2 million kg of PCBs and comprised ... 5.6 million kg Aroclor 1254 ..., U.S. Production: (1974) Approx 41 million lbs, General Manufacturing Information: Domestic USA production of polychlorinated biphenyl, including Aroclor 1254, was stopped in October 1977., The Aroclors are characterized by four digit numbers. The first two digits indicate that the mixture contains biphenyls (12), triphenyls (54) or both (25, 44), the last two digits give the weight percent of chlorine in the mixture (e.g., Aroclor 1242 contains biphenyls with approximately 42% chlorine)., Askarels were often, but not always, a mixture of trichlorobenzenes with PCBs to achieve desired viscosities to permit handling the dielectric as an oily fluid. The capacitor askarels include neat Aroclors 1242, and 1016 and a mixture of 75% Aroclor 1254 and 25% trichlorobenzene. The most common transformer askarels were 60% Aroclor 1260, 40% trichlorobenzene (Type A) and 70% Aroclor 1254, 30% trichlorobenzene (Type D). |
