Contribution of flexographic printing process to ground-level ozone concentrations

The concentration levels of ground-level ozone in the flexographic printing plant were determined in two campaigns during five working days. The first campaign was conducted in the middle, and the second at the end of the eight-hour working time. In the second campaign, the mean ozone values per day (3.81, 3.60, 4.25, 4.71, and 3.18 μg/m3) were almost two times higher than in the first. Still, they were 32 to 47 times lower than the emission limit value prescribed by the Regulation of the Republic of Serbia.
