To determine the lead and cadmium content of soils and sediments, the samples are suspended in water containing 5% (v/v) concentrated hydrofluoric acid before injected into the electrothermal atomizer. For thallium determination a 30% hydrofluoric acid solution is used as the suspension medium. In a
