The Larvae of The Coccinellidae: Illinois Biological Monographs

Evaluates the carcinogenic risks to humans posed by exposures in the dry cleaning industry by eight chlorinated solvents and related chemicals and by an additional group of seven industrial chemicals. Dry cleaning is evaluated in the first and most extensive monograph. Concerning exposures to specific chemicals, tetrachloroethylene is identified as the most commonly used solvent during the last two to three decades.

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.
