Monitoring of inorganic species distribution in water and sediments of Aso river

摘要

Analytical results are reported for the determination of inorganic species in water and sediments sampled in the Aso river ecosystem. The species determined are Cd, Co, Cr, Cu, Fe, Mn, Ni, Zn, Hg, F~-, NO_3~-, SO_4~-, Na, K, Ca, Mg, NH_4~+ in water, and Cd, o, Cr, Cu, Fe, Mn, Ni, 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), wee good, being in all cases lower than 6%.
