This allows to understand the effect of atmospheric PAH contamination on soil PAH content via litterfall. At this aim, we studied mass and PAH dynamics of Quercus ilex leaf litters collected from urban, industrial and remote sites, incubated in mesocosms under controlled conditions for 361d. The results highlighted a litter decomposition rate of leaves sampled in urban&gt;industrial&gt;remote sites; the faster decomposition of litter of the urban site is also related to the low C/N ratio of the leaves. The PAHs showed concentrations at the beginning of the incubation of 887, 650 and 143ngg−1d.w., respectively in leaf litters from urban, industrial and remote sites. The PAHs in litter decreased along the time, with the same trend observed for mass litter, showing the highest decrease at 361d for the urban leaf litter. Anyway, PAH dynamics in all the litters exhibited two phases of loss, separated by a PAH increase observed at 246d and mainly linked to benzo[e]pyrene.</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%">De Nicola, F</style></author><author><style face="normal" font="default" size="100%">Alfani, a</style></author><author><style face="normal" font="default" size="100%">Maisto, G</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Polycyclic aromatic hydrocarbon contamination in an urban area assessed by Quercus ilex leaves and soil</style></title><secondary-title><style face="normal" font="default" size="100%">Environmental Science and Pollution Research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">carcinogenic pahs</style></keyword><keyword><style  face="normal" font="default" size="100%">Diagnostic ratios</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental matrices</style></keyword><keyword><style  face="normal" font="default" size="100%">Light and heavy PAHs</style></keyword><keyword><style  face="normal" font="default" size="100%">Naples urban area</style></keyword><keyword><style  face="normal" font="default" size="100%">PAH toxicity</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year></dates><publisher><style face="normal" font="default" size="100%">Springer Berlin Heidelberg</style></publisher><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">7616-7623</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We investigated the PAH contamination of Naples urban area, densely populated and with high traffic flow, by analyses of environmental matrices: soil and Quercus ilex leaves. Being some PAHs demonstrated to have hazardous effects on human health, the accumulation of carcinogenic and toxic PAHs (expressed as B(a)Peq) was evaluated in the leaves and soil. The main sources of the PAHs were discrim- inated by the diagnostic ratios in the two matrices. The urban area appeared heavily contaminated by PAHs, showing in soil and leaves total PAH concentrations also fivefold higher than those from the remote area. The soil mainly accumulated heavy PAHs, whereas leaves the lightest ones.Median values of carcinogenic PAH concentrations were higher in soil (440 ng g−1 d.w.) and leaves (340 ng g−1 d.w.) fromthe urban than the remote area (60 and 70 ng g−1 d.w., respectively, for soil and leaves). Also, median B(a)Peq concentrations were higher both in soil and leaves from the urban (137 and 63 ng g−1 d.w., respectively) than those from the remote area (19 and 49 ng g−1 d.w., respectively).Different from the soils, the diagnostic ratios found for the leaves discerned PAH sources in the remote and urban areas, highlighting a great contribution of vehicular traffic emission as main PAHsource in the urban area.

Both unwashed and washed leaves showed the highest amounts of trace elements and PAHs in the urban area. Unwashed leaves showed greater differences between urban and remote areas and among the urban sites than washed leaves for trace element and PAH concentrations. Water-washing resulted in a significant (P&lt;0.001) decrease in leaf concentrations of Cr, Cu, Fe, Pb, V and Zn. By contrast, Cd and total PAH concentrations showed no differences between unwashed and washed leaves.</style></abstract><accession-num><style face="normal" font="default" size="100%">17892907</style></accession-num></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%">De Nicola, F</style></author><author><style face="normal" font="default" size="100%">Maisto, G</style></author><author><style face="normal" font="default" size="100%">Alfani, a</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Assessment of nutritional status and trace element contamination of holm oak woodlands through analyses of leaves and surrounding soils.</style></title><secondary-title><style face="normal" font="default" size="100%">The Science of the total environment</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Available soil elements</style></keyword><keyword><style  face="normal" font="default" size="100%">Micro and macro elements</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex L.leaves</style></keyword><keyword><style  face="normal" font="default" size="100%">Total soil elements</style></keyword><keyword><style  face="normal" font="default" size="100%">Vesuvius National Park</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2003</style></year></dates><volume><style face="normal" font="default" size="100%">311</style></volume><pages><style face="normal" font="default" size="100%">191-203</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The nutritional status and trace element contamination of holm oak woodlands in Vesuvius National Park were assessed by analyses of Quercus ilex L. leaves and surrounding soils. The concentrations of Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, V and Zn were measured in 1-year-old leaves, and in the soils at 0-5 and 15-20 cm depths. The potentially available concentrations were also measured for the soils. The leaf element concentrations were similar to the Q. ilex chemical fingerprint, thus indicating a good nutritional status and the absence of short-term trace element depositions. Total K and V were more abundant in the deep soil layers than in the surface ones, whereas Cd and Pb showed higher values in the surface soils. This suggests that long-term soil accumulations of Cd and Pb are due to atmospheric input. The soil availabilities of Cd, Pb and Zn were high, and Cr availability was very low. A correlation between the available concentrations in the deep soil layers and leaf concentrations was found only for Zn.</style></abstract><accession-num><style face="normal" font="default" size="100%">12826392</style></accession-num></record></records></xml>
