Inorganic species in water and sediments of the lamone and marzeno rivers ecosystem

摘要

Analytical results are reported for the determination of inorganic species in water and sediments sampled in the Lamone and Marzeno rivers ecosystem. The species determined are Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn, Hg, F~-, Cl~-, Br~-, NO_3~-, SO_4~--, Na~+, K~+, Mg~++, Ca~++, NH_4~+ i superficial water, and Cd, Co, Cr, Cu, Fe, Mn, Ni, SO_4~--, Na~+, K~+, Mg~++, Ca~++, NH_4~+ in superficial water, and Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn, Hg in sediments. For all the elements, in addition to detection limits, precision and accuracy are given: the former, expressed as relative standard deviation (s_r), and the latter, expressed as relative error (e), were good, being in all cases lower than 6%.
