The genotoxic potential of two occupationally significant chemicals, 4,4'-methylene-bis-2-chloroaniline (MOCA) and 2-phenyl-1,4-benzoquinone (PBQ), was explored by monitoring the induction of mutations at the HPRT locus of AHH-1 human lymphoblastoid cells. Exposure of AHH-1 cells to the putative carcinogenic metabolite of

A new procedure has been developed for the assay of 2,2'-dichloro-4,4'-methylenedianiline (MOCA) using high-performance liquid chromatography with diode array detector. MOCA was sampled from workplace air and derivative before determination using 3,5-dinitrobenzoyl chloride. The determination was carried out in the
