The analytical possibilities of arsenic and other hydride forming elements determination in environmental materials involving hydride generation techniques were discussed. On the basis of some literature reviews, number of factors affecting hydride generation efficiency, such as: element oxidation state in solution, reducer type and concentration, acid type and concentration; hydride generator configuration, matrix components interferences as well as the spectrometer operating conditions were discussed.
