The Finnish Meteorological Institute publishes bulletins about air quality and is responsible for relevant research and development. It also monitors emissions, heavy metals, environmental poisons and ozone levels. High ozone levels are a health hazard. If they exceed a certain value, the public is informed during weather forecasts and on the Internet.
Municipalities are responsible for monitoring air quality locally and releasing information about it. They monitor particles in the air either alone or in collaboration with other local authorities. There are around one hundred measurement stations across Finland.
