Sulphur isotopes as tracers of the influence of a coal-fired power plant on a Scots pine forest in Catalonia (NE Spain)

Stable sulphur isotopes and major ionic composition were analysed in precipitation and throughfall samples from a Scots pine (Pinus sylvestris, L.) forest near the Cercs coal-fired power plant (Catalonia, NE Spain). The purpose of the study was to determine the main sources of sulphur deposition on...

The purpose of the study was to determine the main sources of sulphur deposition on this pine forest. Sulphur isotope measurements from the SO₂ power plant stack emissions were used to identify the isotopic signature of this source. Net throughfall fluxes of sulphur (26.1 kg S ha¹ yr־¹) and nitrogen (16.3 kg N ha־¹ yr־¹) were higher-5-25 times higher for S and 5-15 times for N-at this site than in other forests in Catalonia.

Although power plant contribution to bulk deposition was lower in both cases (34% and 45%), the possible influence of sulphate coming with long-range transport events from the polluted areas in the Mediterranean basin (δ34S≈0‰) was not discarded. 22008-01-0120082008-01-01Articlehttp://purl.org/coar/resource_type/c_6501AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/147692https://dx.doi.org/urn:doi:10.1016/j.atmosenv.2007.09.059reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengMinisterio de Educación y Ciencia CGL2005-08019-C04-01Ministerio de Educación y Ciencia CGL2005-07543/CLIAgència de Gestió d'Ajuts Universitaris i de Recerca https://doi.org/10.13039/501100003030 2005/SGR-933open accesshttp://purl.org/coar/access_right/c_abf2Aquest material està protegit per drets d'autor i/o drets afins.
