The compounds were collected by means of diffusive samplers from August–November 2010 and February–August 2011. Carbonyl compounds, VOCs and O3 were analysed by HPLC with diode array UV–Vis detector, GC–FID and by UV–visible spectrophotometry, respectively. The most abundant carbonyls were hexanal, acetone–acrolein, formaldehyde and acetaldehyde. Seasonal variation was apparent with maximum values observed in summer months. Total carbonyl concentrations ranged from 2.8 to 19.7 μg m−3. Most VOCs studied (using chemically desorbable cartridges) were either not detected or were below their detection limits, however, a parallel sampling using thermally desorbable cartridges, from May 22 to June 19, revealed the presence of much more VOCs, identified using GC–MS. O3 concentration ranged from 27.2 to 90.5 μg m−3, reaching the maximum monthly mean concentration in March (84.4 μg m−3). The analysis of back trajectories indicates the transport of polluted air masses from remote areas, mainly from the Mediterranean basin that should contribute to the high levels of ozone observed.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Librando, V.</style></author><author><style face="normal" font="default" size="100%">Perrini, G.</style></author><author><style face="normal" font="default" size="100%">Tomasello, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Biomonitoring of Atmospheric PAHs by Evergreen Plants: Correlations and Applicability</style></title><secondary-title><style face="normal" font="default" size="100%">Polycyclic Aromatic Compounds</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">correlation</style></keyword><keyword><style  face="normal" font="default" size="100%">GC/MS</style></keyword><keyword><style  face="normal" font="default" size="100%">leaves</style></keyword><keyword><style  face="normal" font="default" size="100%">PAH</style></keyword><keyword><style  face="normal" font="default" size="100%">particulate matter</style></keyword><keyword><style  face="normal" font="default" size="100%">passive samplers</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2002</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2002///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1080/10406630213563</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">22</style></volume><pages><style face="normal" font="default" size="100%">549 - 559</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This article deals with looking for the best passive samplers among eleven plants diffused in the Mediterranean basin for the determination of polycyclic aromatic hydrocarbons in the atmosphere in substitution to the particulate matter sampling.
