This paper presents the results of arsenic, antimony and selenium analyses in the municipal water reservoirs of Poznan. The study concentrates on the discrimination of speciation forms of the determined elements by means of analytical procedures. A specially designed and optimised methodology of hydride generation atomic absorption spectrometry (HGAAS) was employed in the analyses. The limits of detection were established as 0.14 ng/ mL for As (III), 0.16 ng/mL for As (V); 0.17 ng/mL for Sb (III); 0.18 ng/mL for Sb (V) and 0.15 ng/mL for selenium.
