Ribes, Alejandra Fernández Ramón, M. Pilar Appleby, Peter Polycyclic aromatic hydrocarbons (PAH) High mountain areas Soil pollution Lake pollution Long-range transported pollutants Combustion pollution 12 pages, 5 figures, 2 tables.-- PMID: 15210271 [PubMed].-- Printed version published Sep 2004. Polycyclic aromatic hydrocarbons (PAH) in lake sediments and nearby soils of two European high mountain regions, Pyrenees and Tatra, have been studied. Similar mixtures of parent PAH were observed in all cases, indicating predominance of airborne transported combustion products. Nevertheless, the composition of these atmospherically long-range transported PAH was better preserved in the superficial layers of soils than sediments. This difference points to significant PAH degradation process, e.g. during lake water column transport, before accumulation in the latter. Post-depositional transformation was also different in both types of environmental compartments. Thus, lake sediments exhibit higher preservation of the more labile PAH involving lower degree of post-depositional oxidation. However, they also show the formation of major amounts of perylene by diagenetic transformation in the deep sections. This compound is not formed in soils where downcore enrichments of phenanthrene are observed, probably as a consequence of diagenetic aromatization of diterpenoids. Financial support from EMERGE and EUROLIMPACS Projects is acknowledged.
