This paper presents results of determination of the total content of arsenic, antimony and selenium in samples of surface water from selected lakes of Pszczewski Landscape Park. The concentrations of arsenic, antimony and selenium determined by the absorption atomic spectrometry method were up to 0.66 ng/ml, 0.62 ng/ml and 0.76 ng/ml, respectively, at the detection limits of 0.04 ng/ml for As, 0.04 ng/ml for Sb and 0.03 ng/ml for Se. The water samples studied revealed low concentrations of the elements of interest relative to the values obtained for the samples from other regions. The determined concentrations of arsenic, antimony and selenium can be interpreted as natural.

This paper reports results of determination of arsenic, antimony and selenium inorganic species in samples of surface water from the lakes of the Pszczewski Landscape Park located in western Poland. Concentrations of total arsenic, antimony and selenium, determined by atomic absorption spectrometry with generation of hydrides, were up to 0.66 ng/ml, 0.62 ng/ml and 0.76 ng/ml, respectively, at respective detectability limits of 0.04 ng/ml, 0.04 ng/ml and 0.03 ng/ml. For arsenic and antimony the concentrations of the two species determined (As(III)/As(V) and Sb(III)/Sb(V)) were similar, while for selenium the Se(IV) species was dominant.
