Airport

​​​​​​​In 2017, we measure the impact of airport and it's traffic on the air quality in Helsinki-Vantaa . The monitoring station is located in the closed area.

At this monitoring station we measure the concentrations of nitrogen dioxide and fine  particles.

​The results are presented through an air quality index that correlates the concentrations to their health effects. The index varies from good to very poor. When the air quality is poor (red color), people sensitive to air pollutants may show some symptoms. The graph shows the air quality indices from the last 12 hours (unverified hourly values).
