Súhrn: A flow injection hydride generation atomic absorption spectrometric (FI-HG-AAS) method was developed for the determination of arsenic in fish, rice and yeast; of selenium in vegetable, fruit, and dairy products; and of antimony in vegetable, fruit, dairy and bakery products after microwave digestion of samples. Individual steps of the method were optimized and analytical as well as statistical parameters of the method were determined (detection limits: arsenic - 0.068 µg.kg-1, selenium - 0.060 µg.kg-1, antimony - 0.15 µg.kg-1; quantification limits: arsenic - 0.22 µg.kg-1, selenium ­ 0.20 µg.kg-1, antimony - 0.51 µg.kg-1; type C combined standard uncertainties: arsenic - 10.8%, selenium - 8.4%, and antimony - 14.3%). Accuracy of the method was evaluated using BCR-150 skim milk, BGW 08502 Rice Flour and P­ACHK reference materials. The method was used for the determination of arsenic, selenium and antimony in foods consumed in Slovakia.
