Abstract

The aim of the article is to show the role of the redox potential and of the ammonium ion concerning the release of arsenic into groundwater from naturally occurring sources. The study is carried out on both regional and local scale. The former is performed on the area of the drainage basin to the Venice lagoon (DBVL), while the latter interests a sub-area near the Porto Marghera contaminated sites of national interest, named "Agricultural west areas" (AWA). The results of the work will elucidate the processes continuity at different scales.
