- Abstract
- The gas-phase concentrations of polychlorinated naphthalenes (PCNs) (16 congeners) were investigated over 1 year at
two sites in the Venice Lagoon ('marine' and 'industrial') and at a mainland station ('rural'). SPCN concentrations were
mainly composed of lighter congeners and ranged from 191 to 3415 fgm?3 with values comparable with those of
'background' air. The lowest SPCN concentration was detected at the 'marine' site while no significant differences were
found between the 'industrial' and 'rural' stations. The presence of combustion marker congeners in most samples suggests
that this is the main source of PCN at all sites.
The variation of SPCN concentrations over the year showed that the highest values occurred from autumn to early
spring months at the 'industrial' and 'marine' sites, while at the 'rural' station the values were quite homogeneous, with
some peaks in summer. The temperature-PCN relationship was statistically significant only at the 'marine' station, but
with a weak correlation. The linear regression between PCN, PAH and PCB, and the seasonal evolution of their ratios was
investigated to gain a better understanding of the potential sources of PCNs. At the 'marine' site, it may be supposed that
combustion processes constitute PCN sources, with a substantial sea influence. At the 'rural' site, continuous PCN sources
from distant points of emission are hypothesized while the 'industrial' site may be supposed to feature an unidentifiable
continuous source as well as other seasonal sources. (literal)
