| Title | Spatial and Temporal Heavy Metal Concentration (Cu, Pb, Zn, Hg, Fe, Mn, Ni) in Sediments of the Mar Piccolo in Taranto (Ionian Sea, Italy) |
| Abstract | The Mar Piccolo (surface area of 20.72 km2)
is located in the Northern area of the Taranto town
(Ionian Sea, Italy). It is an inner, semi-enclosed basin
with lagoon features connected with the Mar Grande
through two channels which are very important for
water exchange. Mar Piccolo basin is subjected to
urbanization, industry, agriculture, aquaculture and
commercial fishing. Hence, it is important to have a
temporal picture both of heavy metal content and of
organic carbon and their distribution (hydrophobic
fraction, hydrophilic fraction, humic compounds) to
check the progress of pollution in time. Three sediment
cores collected on the basis of the pollution sources
have been analyzed. Both heavy metal and organic
carbon concentrations underline the fact that the
anthropogenic input is different in the three sites, and
that in time the amount of pollutants coming into the
Mar Piccolo have changed in different ways. The high
amount of organic hydrophilic compounds present in
sediments, both due to the small water depth and to the
high accumulation rate, make the sediment site high in
oxygen consumption due to a considerable chemical
and biochemical transformations of organic matter. |
