Imission Measurements during Tunneling Operations

Ambient air quality survey conducted in the past years by imission measurements during tunnelling operations on mountainous sections of the future Croatian highway Zagreb - Split, was preformed in order to monitor workplace air quality for establishing compliance with occupational exposure and air quality regulations currently in force in Croatia. The instrumental method for determination of airborne pollutants quantities in a tunnel excavation was successfully implemented. Described method can be used as an alternative to ISO suggested colorimetric methods using detector tubes for short-term sampling with direct indication.
