ABSTRACT
We present the results of a sedimentological and mineralogical study conducted on 305 marine sediment samples (32 seafloor grab samples and 273 subsea floor samples from 91 vibrocores) collected in the marine area of the eastern Pozzuoli Bay, offshore the area of Bagnoli, that has been the site of heavy industrial activity for more than a century.
The coastal (onland-offshore) area of Bagnoli–Coroglio has been recognised as a contaminated Site of National Interest (SNI) by the Italian Ministry of the Environment (2000–2001) and since then it has been the subject of a series of environmental studies that have documented a severe contamination of soils onland and marine sediments offshore.
Based on the outcomes of the sedimentological classification discussed in this study we have constructed a series of thematic maps illustrating the areal distribution of the sedimentary facies at different stratigraphic levels. Our interpretation provides a support in reconstructing the complex set of environmental changes that have affected the offshore of the eastern Pozzuoli Bay prior to and after the termination of the industrial activity of the Bagnoli brownfield.
Acknowledgements
Seafloor grab samples and vibrocore samples analysed in this study have been collected in 2017 within the frame of the research project ABBaCo (Environmental Restoration of the Bagnoli-Coroglio National Site of Interest) coordinated by the SZN Anton Dohrn, Napoli. Sedimentological analyses have been conducted in the laboratory of ISMAR (formerly IAMC)-CNR, Napoli. Mineralogical analyses have been carried out at IAS (formerly IAMC)-CNR laboratory, Torretta Granitola (TP) and at DiSTAR Federico II university laboratory, Napoli.
