Iron (Fe) represents a highly essential element for various biological processes. In spite of this very little is known as regards its status in mammalian reproductive tissues and factors that may potentially influence it. At the same time, there is an ongoing debate as to whether analyses of the Fe content in hair can provide reliable information on its tissue burden. Therefore, the aim of the present...
The analysis of 238 papers published in the Polish Journal of Environmental Studies concerning investigations on heavy metals conducted in the years 1998-2008 suggests a steadily growing interest in the issue. Investigations on the environmental problems in question are carried out by means of more modern research methods and using the most recent analytical equipment. Research on the role of heavy...
This paper presents a comparative description of different methods of determination of arsenic, antimony and selenium: spectrophotometric, electro-analytical (voltamperometry), activation analysis, atomic fluorescence and the methods of inductive or microwave-induced plasma in combination with different detection methods (emission or mass spectrometry). The description is based on literature data...
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...
This paper reports determination of arsenic, antimony and selenium in different matrices using atomic absorption spectrometry, with atomisation in a graphite tube and with generation of hydrides. The actual state of atomic absorption spectrometry as the method of determining As, Sb and Se is described on the basis of literature data. The effects of interference in determinations by atomic absorption...
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...
This paper shows speciation analysis of arsenic, antimony and selenium using hydride generation atomic absorption spectrometry. Determining different forms of given elements (forms on different oxidation stages: As(III)/As(V), Sb(III)/Sb(V), Se(IV)/Se(VI) and forms bound with organic matter) is based on different kinetics of hydride generation for forms on different oxidation degrees. This paper shows...
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...
This paper presents statistical analysis of results of determination of the total content of arsenic, antimony, selenium and microcomponents in 49 samples of groundwater from an area of western Poland (Wielkopolska). The total content of arsenic reached up to 3.00 ng/ml, antimony 1.25 ng/ml, selenium < 0.15 ng/ml, at detection limits of 0.16 ng/ml for As, 0.18 ng/ml for Sb and 0.15 ng/ml for Se...
