    A third problem was the development of analytical techniques specific to three benzidine-based dyes. “Stop gap” analytical methods were developed utilising pairedion chromatography and separation by high performance liquid chromatography for C.I. Direct Blue 6, C.I. Direct Bl and C.I. Direct Brown In November , the ACCS considered scheduling benzidine-congener-based dyes and benzidine-based azo dye C.I. Acid Black 29 (CAS No. ) in Schedule 7 due to the potential of these substances to be metabolised to carcinogenic benzidine-congeners, similar to that for benzidine-based azo dyes.

Prevention of health hazards from benzidine congener dyes (BCD) is reviewed. The term BCD is defined as commercial preparations of dyes produced from benzidine (), o-tolidine (), or o- dianisidine (). The similarities among the 82 dyes of this type on the market are noted, and their carcinogenic potential is assessed.

carcinogenic effects presented by exposure to benzidine-based and benzidine congener-based dyes, and this Action Plan focuses on human carcinogenicity issues. EPA intends to address risk concerns from potential exposures by initiating rulemaking to add four benzidine-based dyes to.

Abstract. The benzidine dye initiative is a research program established by the National Toxicology Program to generate an integrated body of scientific information regarding the potential health risks associated with exposure to benzidine- and benzidine-congener-derived by: Epidemiological studies have shown occupational exposure to benzidine to result in an increased risk of bladder cancer.

Animal studies have reported various tumor types at multiple sites from benzidine exposure via oral, inhalation, and injection exposure. EPA has classified benzidine as a Group A, known human carcinogen. P.J. Wakelyn, in Cotton, Benzidine and benzidine congener azo dyes.

Many of the direct dyes that used to be used on cotton are benzidine-based OSHA, US NIOSH and other groups in the world have extensively reviewed the literature on benzidine-based dyes (US NIOSH, and a).Available studies indicate that some benzidine-based dyes cause cancer in experimental.

limit benzidine exposure were instituted. A few studies have evalu-ated exposure to benzidine alone; however, in many studies, workers were co-exposed to other chemicals.

Some studies have suggested that the risk of urinary-bladder cancer increases with increasing length of exposure to benzidine (IARC, ).

Since ben. potential exposure to benzidine-based dyes are inhalation and accidental ingestion; dermal absorption can also occur. The potential for exposure has declined since the late s, as benzidine-based dyes were removed from both industrial and consumer.

synthesis of azo dyes referred to as benzidine-based or benzidine congener-based dyes. Examples of benzidine-based dyes are Direct Blue 6, Direct Brown 9, Direct Bl etc. association between exposure to benzidine derivatives or azo dyes metabolized to benzidine and cancer. Three benzidine derivatives used in the manufacture of azo dyes were reviewed: 3,3′-dimethylbenzidine (ortho-tolidine), 3,3′-dimethoxybenzidine (ortho-dianisidine), and 3,3′-dichlorobenzidine.

These benzidine congeners have been evaluated. @article{osti_, title = {Potential health hazards of organic pigments and dyes used in the manufacture of paints and surface coatings.

This Action Plan addresses the use of benzidine-based dyes and benzidine congener-based dyes, both metalized and non-metalized, in products that would result in consumer exposure, such as for use to color textiles. You may need a PDF reader to view some of the files on this page.

See EPA’s About PDF page to learn more. Preventing secondary exposure to dust from settled deposits. Benzidine congener dyes are based on substances chemically similar to benzidine, such as o-tolidine and o-dianisidine, both of which are also carcinogens.

The hazard to health from reactive dyes is only a concern before their application to the yarn or fabric. There is no.

Occupational Safety and Health Administration Varick Street New York, New York Dear Mr. Shapiro: In regards to your January 2, letter concerning sampling for benzidine congener dyes, we give the following responses.

Is there one preferred method for air sampling of benzidine based dyes. If so, what is it?. The risks are (a) to workers exposed to imported benzidine-based dyes that contain high concentrations of free benzidine; (b) to workers using domestically produced benzidine-based dyes (there are no occupational exposure standards for either benzidine or its derivative dyes); (c) to the general population, which may result from exposure to.Erika L.

Abel, John DiGiovanni, in The Molecular Basis of Cancer (Fourth Edition), Benzidine. Benzidine is a member of a large class of carcinogens referred to as aromatic amines. The carcinogenic nature of benzidine was discovered in the context of bladder cancer induction in workers in the dye industry.

37 In the past, benzidine-based azo dyes were synthesized in vast quantities in the. Exposure to benzidine-based dyes are of concern to consumers, workers and children because benzidine dyes can be converted in the body into a chemical that is known to cause cancer.

These dyes also have the potential to separate from textiles, such as clothing, that are in prolonged contact with human skin, increasing exposure risks. Q5.
