ABSTRACT
The present article provides chemical, paleontological and mineralogical data obtained during an archaeometric characterization of 40 samples (33 pottery sherds, 5 clay samples, 1 sand sample and 1 red earth pigment) collected in the Via dei Sepolcri ceramic workshop in Pompeii, Italy. The workshop was still active during the 79 CE eruption of Mt. Vesuvius and the archaeometric data obtained in our investigation reveal distinct differences between pottery and geological raw materials belonging to an early 'Phase 1' production (from the beginning of the 1st century CE to the 62 CE earthquake) and a subsequent 'Phase 2' production (from the 62 CE earthquake to the 79 CE eruption). These data inform the discussions and interpretations presented in the article entitled "A pottery workshop in Pompeii unveils new insights on the Roman ceramics crafting tradition and raw materials trade", edited by Grifa et al. [1].
ABSTRACT
The environmental status of the Falerno-Domitio littoral, a sector of the Italian south coast (Campania region) locally affected by an extensive anthropic pressure and pollution, was assessed by a multi-disciplinary approach, consisting of geological vs. biological studies. Geochemical abundance of potentially hazardous trace metals in beach sands is mainly constrained by the nature of the source rocks. Geochemical data of marine sediment quality with regards to possible heavy metal pollution and the enrichment factors of selected potentially toxic metals show that Cr and V values are higher in marine samples than in natural sources, suggesting that they are, at least in part, of anthropic derivation. A relationship between meiobenthos and heavy metals (Cr, Co, and V) has been also observed, providing a valuable biological marker to human-deriving chemical pollution. Ecotoxicological analyses confirm a relationship between enrichment in selected metals and moderate toxicity of some sea-bottom sediments closer to the coastline.
