Sediment reference concentrations of seldom monitored trace elements (Ag, Be, In, Ga, Sb, T1) in four Swedish boreal lakes - Comparison with commonly monitored elements

摘要

This paper presents reference and recent acid-leachable concentrations of some seldom monitored trace elements (SMTE; Ag, Be, Ga, In, Sb and TI) in sediments from four boreal oligotrophic lakes in a south to north transect in Sweden. For comparison commonly monitored trace elements (As, Cd, Co, Cr, Cu, Ni, Pb and Zn) are included as well as those of relevance for redistribution processes (Al, Ca, Fe, Mg and Mn).
