title: Biological monitoring of workers exposed to 4,4'-methylenebis (2-chloroaniline) (MBOCA).
abstract: A biological monitoring programme has been developed for assessing occupational exposure to 4,4'-methylenebis (2-chloroaniline) (MBOCA) in a factory which manufactures polyurethane elastomers. In a systematic programme of biological monitoring over a five year period urinary MBOCA concentrations have been used to provide evidence of absorption of MBOCA. Improvements in the handling and use of MBOCA have coincided with a steady reduction in the urinary MBOCA concentrations.
