Printing Processes and Printing Inks, Carbon Black and Some Nitro Compounds.

This volume of the IARC Monographs evaluates the carcinogenic risks to humans posed by exposures in printing processes and to printing inks, to carbon black, and to selected nitro compounds, many of which are used in the production of dye and colourant intermediates. The first monograph evaluate occupational exposures in printing processes and to printing inks. Exposures in the printing industry are assessed according to their occurrence in printing ink manufacture and in printing operations such as letterpress, lithography, flexography, gravure, and screen printing. Although many epidemiological studies have demonstrated some evidence of cancer risk in printing trades and printing industries, the assessment found several important problems in the design of these studies. Occupational exposures in printing processes were classified as possibly carcinogenic to humans. Printing inks could not be classified.
