Description:
The Late Quaternary benthic foraminiferal and ostracod assemblages from two continuous cores drilled
in the Port of Salerno were studied to define their relationship with geochemical characteristics
of the sediments and with the palaeoenvironmental evolution. The succession, ranging from Late
Pleistocene to the 20th century, recorded the transition from a marine coastal environment under
natural conditions to a depositional context affected by anthropogenic influence. In the lower part
of the sequence, ecological and sedimentary changes were linked to sea-level changes due to Late
Quaternary climatic phases, as well as to volcanic events such as the Campanian Ignimbrite eruption,
represented by levels with high metal (Fe, Mn, Pb, Zn) concentrations, possibly leading to low pH
phases. Later human activities, such as the construction of harbour facilities in the 18th century and
the industrial development in the 19th century, influenced environmental variations, as shown in the
upper part of the succession. High levels of heavy metal concentrations (Co, Cu, Fe, Pb, V) recorded
in layers deposited in the 1800s suggest the presence of a pollution event which could be linked to
manufacturing activities and might have occurred during the first part of the 19th century. Calcareous
meiofaunal assemblages showed high diversity values, probably due to the occurrence of "rare short
lived" species in an unstable environment. Assemblages were dominated by the foraminiferal species
Ammonia aberdoveyensis and Haynesina depressula, and by the ostracods Pontocythere turbida and
Semicytherura sulcata, which are considered as possibly stress-tolerant species.
