Source-receptor (SR) relationships

Source-receptor (SR) relationships are a type of data developed by the Cooperative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe (EMEP). SRs provide information on the change in air concentrations, deposition or impacts that arise from changes in emissions from different emitting countries.
Each figure which follows provides an indication of the distribution of imported air pollution by country. Results are dependent upon the version of the EMEP model being used, the absolute magnitude of emissions, and meteorological drivers
