We monitor air quality in 2018 in Kauppalankatu 1, which is a busy traffic environmenti in the centre of Hyvinkää. Before this, air quality was monitored at the same place in 2008, 2013 and 2014.
In Hyvinkää we measure, among others, the concentrations of nitrogen dioxide and respirable particles in the air. Hourly concentrations are shown on our website. The results describe the air quality of an area with busy traffic.
The results are presented here through an air quality index that correlates the pollutants to their health effects. The index varies from good to very poor. When the air quality is poor (red colour), people sensitive to air pollutants may show some symptoms.
The graph shows the air quality indexes from the last 12 hours.
