Contamination levels of PAHs in marine environment by sea urchin Paracentrotus lividus GCITMS analysis in Sardinia / Angioni, Alberto; Cau, Alessandro; Secci, Marco; Addis, Pierantonio. - In: MARINE POLLUTION BULLETIN. - ISSN 0025-326X. - 82:(2014), pp. 201-207. [10.1016/j.marpolbul.2014.02.031]
Abstract:
This paper describes the results of a two-year monitoring study examining the pollution of the sea urchin
Paracentrotus lividus by polycyclic aromatic hydrocarbons (PAHs) in Sardinia. GC–ITMS analysis of sea
urchin gonads showed the presence of 11 and 12 PAHs in the samples of Capo Pecora, and Capitana,
respectively. Fluorene, naphthalene and its two degradation products, 1-methyl-naphthalene, and
2-methyl-naphthalene, were detected in all samples analyzed. The RPAH residues showed a similar trend
over the two-year sampling period. Furthermore, the residues in the first year were slightly higher than in
the second year. The information obtained by the multivariate statistical analysis PLS-DA allowed for the
determination of samples based on field site and varying habitat types (rocky reef, and Posidonia seabed).
The results of this study showed that Posidonia sea urchins are contaminated by high molecular weight
PAHs and that Capitana samples are more contaminated due to a higher level of human activity in the
area.
