Key words:
Rotogravure printing, rotogravure inks, genotoxicity, polycyclic aromatic
hydrocarbons, toluene, 1-hydroxypyrene, and 3-hydroxybenzo/a/pyrene
Abbreviations:
PAHs = polycyclic aromatic hydrocarbons
3-OH benzo/a/pyrene = 3-hydroxybenzo/a/pyrene
1-OH pyrene = 1-hydroxypyrene
Abstract:
The objective of this study was to distinguish the effect of toluene from the
possible effect of printing inks in rotogravure printing, where a higher incidence
of chromosome aberrations in lymphocytes of workers has been repeatedly reported.
Rotogravure printing inks were examined as a potential source of genotoxic polycyclic
aromatic hydrocarbons in carbon black, which is present in the black ink. Polycyclic
aromatic hydrocarbons with carcinogenic properties were not discovered in the inks.
The concentrations of polycyclic aromatic hydrocarbons in the air of the rotogravure
workshop reached only tens of ng · m-3, a level comparable with their concentrations
in the urban atmosphere of a relatively clean part of the city. Urinary levels of
free 1-hydroxypyrene in the group of 23 printers were not significantly different
from the control group of 22 persons, and the level of free 3-hydroxybenzo/a/pyrene
was under the quantitative limit of both groups.
These results do not confirm the potential genotoxic
danger of PAHs in rotogravure printing, where the widely used toluene is another
suspected factor of genotoxicity.
