Occurrence of arsenic, antimony and selenium in surface waters of Drawienski National Park

This paper reports the results of determinations of total amounts of arsenic, antimony, selenium and macrocomponents in water samples from lakes in Drawieński National Park. The total content of arsenic was up to 0.95 ng/mL, antimony up to 0.53 ng/mL, while selenium was below 0.15 ng/mL, at the limits of detectability of 0.16 ng/mL 0.18 ng/mL and 0.15 ng/mL, respectively. The water samples studied had a relatively low content of the elements determined in comparison to their content in water samples from other regions of Poland.Taking into regard that the samples were collected from an area under special protection, the contents of arsenic, antimony and selenium determined in them can be interpreted as representing the natural level of these elements.
