Environmental toxicology and chemistry, 24(5), 1022-1028 (2005-08-23)
Aromatic amines, such as benzidine and 3,3'-dichlorobenzidine (DCB), are part of the dyes and pigments manufacturing process. The prolonged use of these carcinogenic chemicals in the past generation has introduced a significant amount of contamination to the environment. Their persistency

DCB, 3,3'-dichlorobenzidine, is used primarily as an intermediate in the manufacture of diarylide yellow or azo red pigments for printing ink, textile, paint, and plastics. It is also used in tattoo inks. In this article, we investigate light-induced toxicity of

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
R Joppich-Kuhn et al.
International archives of occupational and environmental health, 69(4), 240-246 (1997-01-01)
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
