Effects of desferrioxamine-B on the release of arsenic from volcanic rocks
چکیده انگلیسی
►Origin of arsenic in volcanic aquifers. ►The ability of siderophore to complex iron can trigger arsenic mobilization from volcanic rocks. ►Levels above 250 μM Dfob siderophores noticeably enhance arsenic release in lava, tuff, peperino and unconsolidated fallout deposits within 30 days period. ►Arsenic 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. ►The 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.
