| Title | Ecotoxicological effects of sediments from Mar Piccolo, South Italy: toxicity testing with organisms from different trophic levels |
| Abstract | Italy) is a semi-enclosed and strongly polluted basin. For decades,
it has been subjected to different anthropogenic impacts.
These stressors caused severe sediments contamination
with high concentration of different pollutants (PAHs, PCB,
heavy metals). In order to assess the current status of sediments
contamination, an ecotoxicological investigation combined
with chemical analysis (heavy metals, PAH, and PCB)
has been performed. In order to derive ecologically relevant
conclusions, a multiorganisms and multiend-points approach
has been applied, exposing organisms from different trophic
levels to elutriate and whole sediment. The battery of bioassays
consists of a microalgal growth inhibition test
(Dunaliella tertiolecta), acute and sublethal assays (endpoints:
mortality, immobilization and swimming speed alteration)
on crustaceans larvae and juveniles, and rotifers
(Amphibalanus amphitrite, Artemia salina, Corophium
insidiosum and Brachionus plicatilis), and embryotoxicity test
on echinoderms (Paracentrotus lividus). Considering the high
levels of sediment contamination highlighted from chemical
analysis, an unexpected very low toxic effect was observed,
even considering the sublethal end-point (larval swimming
speed alteration). The results of this study suggest a very complex
contaminants dynamic in the Mar Piccolo sediments that,
despite a strong level of contamination, seems to not affect in a
proportional manner the biological compartment. |
