title: Determination of arsenic and selenium in environmental and agricultural samples by hydride generation atomic absorption spectrometry.
abstract: Agricultural and environmental samples are digested with acid, and arsenic and selenium are determined using hydride generation atomic absorption spectrometry. Interelement interferences are eliminated by high acid concentrations or cation-exchange resins. Agreement with standard reference material is excellent. The technique is also applied to actual samples.
