Abstract

Polycyclic aromatic hydrocarbons (PAHs) were determined by the GC-MS chromatography in the leaves of Quercus ilex L., an evergreen Mediterranean oak,to monitor the degree of pollution in the urban area of Naples compared toremote areas. Leaf samples were collected in July 1998 from four urban parks, six roadsides and two sites in remote areas. The total PAH contents in Q. ilex leaves ranged from 106.6 in a control site to 4607.5 ng/g d.w. along a road with a high traffic flow. The mean concentration factors (urban/control) were 3.8 for the parks and 15 for the roads. The contribution of carcinogenic PAHs (benz[a]anthracene, benzo [b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenz[a,h]anthracene, indeno[1,2,3-c,d]pyrene) was higher in urban area and differed according to the site, ranging from 6.7% to21.3%. The total PAH burden in control sites was dominated by the low molecular weight PAHs, whilst along the urban roads fluroanthene pyrene and benz[a]anthracene among the measured PAHs showed the highest values. PAHs werepositively correlated (P < 0.01) to trace metals measured in a previous study. (C) 2001 Elsevier Science Ltd. All rights reserved.
