Naples Bay is affected by metal contamination of geogenic and anthropogenic nature. The grain size, organic matter, nutrients, and metal content of the seafloor sediments were analysed through a statistical approach, and a comparison was made with data ashore. The results identified four zones: one contaminated by volcanic rocks; a second and third zone contaminated by anthropogenic inputs; and a fourth distal zone with a low contamination rate. The results show that the river should be considered as a major source of anthropogenic contamination.
