Compounds In The Portuguese Printing Industry

Abstract
In the printing industry, volatile organic compounds main sources are the uses of
organic solvents, fountain solutions and cleaning agents.
Nowadays, one circumstance which might confuse the exposure reality is that
the majority of solvents which are often used have a faint odour. Therefore, the
conditions at offset printing in regard to solvent exposure may seem acceptable
to workers. Fortunately, general ventilation and local exhaust systems have also
become more common, and new printing machines, often with automatic
cleaning, have entered the market.
The health effects of volatile organic solvents are dependent on the chemicals
involved but, normally, are associated with affecting the nervous system, the
liver and also the kidneys.
The purpose of this study was to document the conditions regarding exposure
to volatile organic compounds in an offset printing unit and to permit identify
task with higher exposure and with priority for preventive measures application.
Exposure assessment was done before and after installation of general
ventilation and local exhaust equipments and during printing and cleaning
procedure. It was use portable VOCs measurement equipment with real-time
measurements (MultiRAE, RAE Systems model) that allowed identify task with
higher exposure.
The need and appropriateness of ventilation introduction is measured by the
significant statistically difference (p<.001) in the concentration results before
