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

A method based on gas chromatography/mass spectrometry-negative ion chemical ionization detection (GC/MS-NCI) was developed for the determination of 3,3'-dichlorobenzidine (DCB)-hemoglobin adducts. Adducts were released from hemoglobin by mild alkaline hydrolysis and determined by GC/MS-NCI after extraction and derivatization with heptafluorobutyric

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

3,3'-Dichlorobenzidine (DCB) and its degradation products, 3-chlorobenzidine (MCB) and benzidine, are of environmental concern because of their carcinogenic nature. The suitability of a small Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer for the analysis of these environmental contaminants in
