This study is considered as one of the most important and useful studies
in the field of environmental impact assessment for industry in general and
printing industry sector in particular. Also a few studies were carried out in
the Arab world in this field but in Libyan Arabic Jamahiriya; this study may
be the first. On the other hand, the present study aims to study and evaluate
the environmental and health impact of indoor pollutants in some printing
presses in Libya and how to mitigate it, then we chose three cities (Sirte,
Misurata and Tripoli) and two presses in each city.
In the present study the concentration of the following pollutants at
indoor air of the studied presses were estimated:
* Gaseous pollutants (CO, SO2, NO3 and O3), the results indicated that the
concentration of SO2, NO2, and O3 are in higher levels than Maximum
Allowable Concentration (MAC).
* Volatile Organic pollutants (Benzene, Xylene, Methanol, Acetone and
Carbon tetrachloride), the results of the measurements showed that the
concentration of both benzene and carbon tetrachloride exceeded the
* Dusts of Heavy Metals and Total Suspended Particulates (TSP), the results
showed that all the above issues are more than MAC.
