Welcome to the UK Air Pollution Information System (APIS). Air pollution is one of the major environmental issues in the UK, with impacts occurring at local, regional and global scales. Much is known about the impacts on natural heritage features, with major steps already being taken in the development of abatement strategies both at national and international levels. It is clear, however, that there are still major gaps in the scientific understanding. This site provides a searchable database and information on pollutants and their impacts on habitats and species.
