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 ismainly 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 biologicalmarker to human-deriving chemical pollution. Ecotoxicological analyses confirm a relationship between enrichment in selected metals andmoderate toxicity of some sea-bottom sediments closer to the coastline.
