Abstract: DETERMINATION OF TOTAL As AND INORGANIC ARSENIC SPECIES FOR THE ENVIRONMENTAL QUALITY MONITORING OF GROUNDWATERS. This work reports an alternative, fast and robust method, for the determination of total As, As( III) and As(V) by HG-AAS without the use of prereductants. The method is based on the different rates of arsine formation of the inorganic As species and the effect of As( III) in the signal obtained for total As. Groundwater and mineral spiked waters were used to sample preservation evaluation. The method was validated by the determination of As in SRM 1640 and used in the determination of total As and its inorganic species in groundwater samples collected from mines in the Iron Quadrangle - MG.
