Application of Source-Receptor Techniques to the Assessment of Potential Source Areas in Western Mediterranean
Receptor-oriented methodologies have been recently used to provide maps of potential sources for particular target species. Here, a receptor-oriented methodology has been applied to the chemistry of precipitation data collected at a background site in NE Spain (La Castanya rural station, LC) in order to identify the likely sources of anthropogenic pollutants (SO4 2-, NO3-, NH4+) and alkaline species to this site. The concentration fields were obtained on the basis of the residence time of the air mass trajectories in each source region.
