| Title | Methodological approach for metal pollution evaluation in sediments collected from the Taranto Gulf (Ionian Sea, Southern Italy). |
| Abstract | The concentrations of Hg, Cd, Pb, Cu, Ni, V, and Sn were determined in marine
sediments collected from Taranto Gulf (Ionian Sea, Southern Italy). The aim of
this article is to study the methodological approach in order to evaluate total
metal levels determined in marine sediments of a contaminated area (Taranto
Gulf, Southern Italy), to identify contaminated areas and to predict adverse
biological effects based on Sediment Quality Guidelines (SQGs). The results are
discussed in relation to geological characteristics of sediments in order to define
background levels and anthropogenic input. Experimental results were elaborated
by multivariate statistical techniques and Geographical Information System
(GIS) software. The geoaccumulation index Igeo and two sets of SQGs (in
particular (a) the threshold effect level (TEL), the probable effect level (PEL) and
(b) the effect range-low (ERL) and the effect range median (ERM)) have been
used for environmental evaluation of metal concentrations. Results show that in
Taranto coastal area, Mar Piccolo basin represents the most contaminated area.
A comparison with results from other Mediterranean areas demonstrates that for
some metals (such as Cd, Pb, and Hg) Taranto seas represent one of the most
polluted areas in the Mediterranean Sea. A comparison of metal levels with SQGs
also suggests an ecotoxicological risk for benthic organisms mainly in the first
inlet of Mar Piccolo. |
