The meltwater flow from a continuous ice core melting system was split into two aliquots, with one aliquot directed to an inductively coupled plasma quadrupole mass spectrometer for continuous trace elements determinations and the second introduced into a solid phase C18 (SPE) cartridge for semicontinuous PAH extraction. The depth resolution for PAH extractions ranged from 40 to 70 cm, and corresponds to 0.7-5 years per sample. The concentrations of 11 PAH were determined in dated snow/ice samples to reconstruct the atmospheric concentration of these compounds in Europe for the last 300 years. The PAH pattern is dominated by phenanthrene (Phe), fluoranthene (Fla), and pyrene (Pyr), which represent 60-80% of the total PAH mass. Before 1875 the sum of PAH concentration (PAN) was very low with total mean concentrations less than 2 ng/kg and 0.08 ng/kg for the heavier compounds (Sigma PAH*, more than four aromatic rings). During the first phase of the industrial revolution (1770-1830) the PAH deposition showed a weak increase which became much greater from the start of the second phase of the industrial revolution at the end of 19th Century. In the 1920s, economic recession in Europe decreased PAH emissions until the 1930s when they increased again and reached a maximum concentration of 32 ng/kg from 1945 to 1955. From 1955 to 1975 the PAH concentrations decreased significantly, reflecting improvements in emission controls especially from major point sources, while from 1975 to 2003 they rose to levels equivalent to those in 1910. The Fla/(Fla+Pyr) ratio is often used for source assignment and here indicates an increase in the relative contribution of gasoline and diesel combustion with respect to coal and wood burning from 1860 to the 1980s. This trend was reversed during the last two decades."@en ; prodottidellaricerca:prodottoDi modulo:ID6305 , istituto:CDS028 , modulo:ID5677 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA11539 , unitaDiPersonaleEsterno:ID10382 , unitaDiPersonaleEsterno:ID17751 , unitaDiPersonaleEsterno:ID14895 , unitaDiPersonaleEsterno:ID6030 , unitaDiPersonaleEsterno:ID2093 . ns12:ID393908 pubblicazioni:rivistaDi prodotto:ID20310 .
