%X This paper reports a study of the occurrence and
levels of polycyclic aromatic hydrocarbons (PAHs) in a bay
characterised by a chronic persistent impact. A total of 55
sediment samples were taken at different depths up to
111 m in two sampling campaigns. Chemical analyses were
carried out by gas chromatography-mass spectroscopy. The
results indicate that: (1) significant spatial variations exist,
(2) levels of PAHs are related more strongly to the spatial
distribution of sediments than to mineralogy/granulometry,
(3) the sediments are slightly-to-moderately contaminated
by PAHs, and (4) these PAHs derive from pyrolytic and
petrogenic sources. Through use of an innovative data
classification system (proposed according to depth and
spatial location of sampling points), and using factorial and
cluster techniques, five zones have been differentiated
depending on the contamination level and source.
