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
Marianne C Nyman et al.
Environmental toxicology and chemistry, 21(3), 500-506 (2002-03-07)
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
