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.

New look and data for UK’s Air Pollution Information System (APIS)

The UK’s leading web database on the impacts of air pollution on the natural environment, APIS, has been given a makeover – it’s now easier than ever to search for the information you want.

APIS is freely available and provides users with a one-stop-shop to evaluate the impact of air pollution on natural habitats. It is used by the UK’s air pollution regulators and local planning authorities to evaluate air pollution impacts as part of their consenting or permitting work.

The new, improved APIS also provides site specific data on nitrogen and acid deposition across the whole UK network of protected sites. Pollutant deposition and concentration data is available for all locations through a ‘search by location’ tool. Each Area/Site of Special Scientific Interest is now listed as well as the UK’s areas of European importance, which were previously available.

New study shows extensive impacts of nitrogen deposition across UK

JNCC has recently published an analysis of national vegetation data sets in relation to nitrogen deposition.  The study clearly demonstrated significant changes in the abundance of individual species and variables describing habitat structure and function as a result of N deposition.  This, together with previous evidence from surveys and experiments, provides clear evidence of impacts of N. 

Europe's wildlife under threat from nitrogen

A new book, Nitrogen Deposition and Natura 2000 ,  has been published of the proceedings of an international workshop which warns of the risks to European wildlife from nitrogen pollution resulting from industry and agriculture.  The issue presents a serious challenge for the conservation of natural habitats and species under the Habitats Directive.
