Measurements
Since 2008, BBT SE has been carrying out an extensive immission measurement programme in the Tulfes-Innsbruck-Steinach project area. The measurements are being used to monitor the level of immissions before, during and after the construction phase, as well as to monitor construction and issue alerts in the event of relevant emission episodes. Part of the measurement programme is the ONLINE monitoring of particulate matter (PM10) and nitrogen oxide pollution with recording of wind direction and wind speed at six locations. Furthermore, atmospheric inputs (heavy dust) are being monitored by means of dust precipitation measurements, including chemical analyses. In addition, temperature and humidity measurements are being taken at the “Sill Gorge" and "Ahrental" tunnel portals at 0 m, 50 m and 100 m from the respective tunnel portals to document small-scale climatic changes.
