| Title | Organic pollutants (PAHs, PCBs) and ecotoxicological evaluation in sediments of Mar Piccolo of Taranto (Ionian Sea, Southern Italy). |
| Abstract | Polychlorinated biphenyls (PCBs) and 17 parent polycyclic aromatic hydrocarbons (PAHs) were determined in surface sediments
from nine stations in the Mar Piccolo of Taranto (Ionian Sea, Southern Italy). Total PAH concentrations ranged from 380 to
12,750 lg/kg d.w., while total PCB levels ranged from 2 to 1684 lg/kg d.w.; this values were higher than those found in others marine
coastal areas of the Mediterranean Sea. For PAHs, low molecular weight/high molecular weight, phenanthrene/anthracene and fluoranthene/
pyrene ratio were used for discriminating between pyrolitic and petroleum origin. Results showed that PAHs were mainly
of pyrolitic origin. PCB and PAH levels in sediments were compared with Sediments Quality Guidelines (ERMERL, TELPEL
indexes) for evaluation probable toxic effects on marine organism. Finally, ERM and PEL quotients were used to evaluate the degree
to which chemicals exceed guidelines. Results suggest an ecotoxicological risk for benthic organisms mainly in the first inlet, where high
concentrations of PCBs were found in sediments influenced by harbour activities |
