NO<sub>x<\/sub> are a sum of nitric oxide (NO) and nitrogen dioxide (NO<sub>2<\/sub>) which, along with PM<sub>2.5<\/sub>, are the main air pollutants of concern in London. They are harmful to human health and are associated with adverse health outcomes like asthma, strokes and cancer.<\/p>\n<p>London also has emissions inventories for NO<sub>x<\/sub> and PM<sub>2.5<\/sub>, meaning there is a detailed list of all the activities contributing to these pollutants across the city. The model that is behind the dataset requires these emission inventories.<\/p>\n<p>This is the first time that modelled pollution sources data has been displayed in this detail across Greater London on an interactive public map.
