Flow-through stripping chronopotentiometry was used for the determination of antimony in soil sam­ples. Antimony was deposited in potentiostatic mode on a glassy carbon porous electrode coated with Nafion® and mercury and then stripped with constant current. The accuracy of the results was confirmed by graphite furnace atomic absorption spectrometry. The LOD and LOQ were found to be 0.6 ^g dm-3 and 1.7 ^g dm-3, respectively. A linear response range was observed in the concentration range of 1 to 200 ^g dm-3 for sample volumes of 4 ml. The repeatability and reproducibility were found to be 2.9% and 5.2%, respectively.

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. The samples showed low values of the content of the elements considered relative to the values obtained for water samples from other regions. As the groundwater samples were collected from isolated water bearing horizons, the values determined for them could be treated as geogenic.

Maize (Zea mays) growing in soil watered with Sb mine drainage (SMD) could accumulate Sb and transferred Sb from roots to shoots. The photosynthetic processes in the leaves were clearly inhibited by SMD. Chlorophyll synthesis was inhibited. Photosystem II (PSII) was sensitive to SMD. PSII activity (FV/FM and PIABS) was reduced due to SMD. Irrigation with SMD resulted in an increase in the proportion of the closed PSII reaction centers (RCs) and a decrease in the proportion of QB binding centers. The electron transport on both the donor side and the acceptor side was inhibited by SMD. The total electron transport flux in PSII was reduced and the electron transport beyond QA¯ was the primary target site for toxicity of SMD. PSII RCs were transformed into dissipative sinks for excitation energy under stress of SMD. Sb accumulation in crops due to SMD irrigation may not only reduce crop growth and yield, but also pose a threat to food security and human health.

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 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.

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 illustrating the present state of the metalloid determinations in different matrices. The limits of determination ensured by different methods are also compared. Much attention has been paid to methods combining chromato- graphic separation with selective detection, especially with the application of plasma generation methods (usually ICP-MS).

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 steps for speciation analysis as described in literature, the main procedures and reagent used in different studies.

This paper presents results of the determination of the total concentration of arsenic, antimony and selenium and their inorganic speciation forms in water samples from grate ashes dumping grounds. Determined concentrations of elements were up to 128.8 ng/mL for arsenic, 153.7 ng/mL for antimony and 52.9 ng/mL for selenium, at the detection limits of 0.16 ng/mL for As, 0.18 ng/mL for Sb and 0.15 ng/mL for Se. Water from some study sites was characterized by very high concentrations of determined elements, which were used to follow their migration. Leakage of dangerous micro-pollutants to ground water was stated. Based on results of speciation analysis the vertical migration of pollutants through unsaturated zone was found.

This study was aimed at recognizing the levels of arsenic, antimony and selenium concentrations in different zones of the lake ecosystem. Total content as well as inorganic species of the studied metalloids were considered. Shallow Lake Jarosławieckie (Wielkopolski National Park) was chosen for the study reported. Water samples were collected in different macrophyte communities of the phytolittoral and in the middle of the lake in early spring and mid-summer 2002. Total concentrations of all studied metalloids in samples collected in summer were lower than in those collected in spring but not all studied mineral species of As, Sb and Se followed the same pattern of changes. Despite seasonal changeability the lack of significant spatial differentiation in the concentrations of the elements studied at the peak of the vegetation season, in particular no differences in their concentrations between the sites in the bulk water in the middle of the lake and the sites in the plant communities was stated. This finding might testify to the fact that the effect of vegetation on the concentration of the elements studied is limited.

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 spectrometry, and the problems related to sample preparation to determinations (extraction, mineralisation, concentration) are discussed. The application of flow injection analysis in atomic absorption spectrometry with hydride generation is described. The effectiveness of atomic absorption spectrometry in speciation determinations of arsenic, antimony and selenium applied alone and in combination with chromatographic methods is shown.

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.

Opracowano efektywny sposób mineralizacji lub ekstrakcji osłonek i siatek stosowanych jako opakowania do wędlin. Efekty obydwu procesów śledzono oznaczając w mineralizatach i ekstraktach całkowitą zawartość arsenu, antymonu i chromu. Uzyskane wyniki wskazują, że dopuszczalne poziomy jonów metali ciężkich dla środków spożywczych nie zostały przekroczone przez producentów badanych osłonek do siatek.
