چکیده انگلیسی
âºOrigin of arsenic in volcanic aquifers. âºThe ability of siderophore to complex iron can trigger arsenic mobilization from volcanic rocks. âºLevels above 250 μM Dfob siderophores noticeably enhance arsenic release in lava, tuff, peperino and unconsolidated fallout deposits within 30 days period. âºArsenic released is correlated to iron release. As/Fe trend shape evidenced different release mechanisms in the studied volcanic rocks, related to the peculiarity of As distribution on the surface and the strength of Fe bonds present in the rocks. âºThe mobilized amount of As significantly correlates with released Al, Si, Mn and Fe as major rock constituents and V, Ga, Sb as minor elements commonly found in geothermal fluids.
