3,3'-Dichlorobenzidine (DCB), which has been assigned as a possible carcinogen to humans (Group 2B) by IARC, is produced as a raw material in the manufacture of polymers and dye intermediates. In our previous paper, we identified DCB as an indirect-acting

Laboratory experiments have been conducted to elucidate the photochemical behavior of 3,3'-dichlorobenzidine (DCB) and its congeners in aquatic systems. Photodechlorination of DCB was observed in aqueous samples that were irradiated with monochromatic radiation from a variable-wavelength laser at several wavelengths

3,3'-dichlorobenzidine (DCB) can be metabolically N-acetylated and/or N-oxidized, and can form hemoglobin adducts. Gas chromatography/mass spectrometry-selected ion monitoring detection mode (GC/MS-SIM) could be a good analytical method to detect them. 4-Aminobiphenyl and phenanthrene-d10 were used as internal standards, and standard

3,3'-dichlorobenzidine (DCB) is suspected to be arcinogenic in experimental animal and human. Several studies have investigated excretion of metabolites in urine, hemoglobin adduction and cancer incidence among workers exposed occupationally to DCB. In these researches, metabolites of DCB had a

In a chemical plant in Germany producing 3,3'-dichlorobenzidine dihydrochloride for the manufacture of colorants, blood and urine samples were taken for biological monitoring. 3,3'-Dichlorobenzidine (DBZ) was analyzed in urine by thin-layer chromatography and subsequently further combined with analysis of adducts
