Abstract
Hydride generation (HG) and graphite furnace atomic absorption spectro scopy for determination of arsenic in various foodstuffs are compared. Two methods of sample pre-treatment, wet ashing and pressurized decom position in an autoclave, are discussed in detail. It is shown that, f or the determination of arsenic in foodstuffs, the HG technique is pre ferable. The relative standard deviation for arsenic determined by the HG technique does not exceed 15.4% for three parallel weighed samples with an arsenic content of 1.0 mg kg(-1).
