This metastable phase is an important sink for trace metal(oid)s including Cu, As, Zn, Mn and Ni. However, schwertmannite recrystallizes to goethite in the short-term followed by its transformation to hematite over long time scales. Terraces that form in AD-impacted rivers commonly exhibit a transition from schwertmannite to these more crystalline phases over time [1,2]. One of the largest massive sulfide provinces worldwide, the Iberian Pyrite Belt (IPB), is located in the Southwestern Iberian Peninsula. This metallogenic province hosted originally more than 1700 Mt of massive sulfides [3]. This study aims to constrain the behavior of sorbed trace elements during aging of schwertmannite terraces formed within AD-impacted rivers in the IPB. Knowing the final fate of trace elements will improve remediation systems designs. Samples of these terraces were obtained from two locations in the Tinto River basin...

The acronym RAMAS arises from the project title "Risk Assessment and risk Management procedure for ArSenic in the Tampere region". The project is targeting the Province of Pirkanmaa which comprises 28 municipalities, and has 469 000 inhabitants within its area.

Data was acquired about chemicals containing arsenic (wood preservative agents, pesticides etc.), the metal industry and metallic products containing arsenic (e.g. gunshots), mining and waste management. Available data was gathered from the Chemical Register (KETU), the Register of Contaminated Land Areas and the Register of Surface Waters maintained by the Finnish Environment Institute (SYKE) and the Regional Environment Centers of Finland, from environmental authorities and other very diverse sources. Dozens of unpublished file reports on the risk assessments and remediation of contaminated soils provided by consulting companies and previous studies made by the Regional Environment Centers of Finland were studied to gather information about arsenic contamination. Information about environmental impacts of mining industry was obtained from geological publications. The data acquisition was difficult because information about contamination, concentrations and risk assessments of arsenic is scattered in unpublished reports and informal papers. RAMAS studied areas affected by soil and surface water contamination in one wood preservative plant (52 field analyses and 5 samples analyzed in laboratory), two mines (6 tailings samples analyzed for geochemical composition, leachability and toxicity, 6 lake and stream sediment samples and over 60 surface water samples), waste treatment and municipal waste water treatment plants. In total, over 100 samples were analyzed.

The Fe-stromatolites studied in the highly polluted
