Note: The Ministry of Ecology and Environment has revised the technical standards for air quality monitoring, affecting data from the beginning of 2019. Data for previous years has been revised to conform with the new standard, according to the ministry, but revised data has not been made available. This can cause differences of up to several percentage-points, but data is reflective of overall trends.
