title: [Contribution to the determination of thallium in human head hair in forensic cases with flameless atomic absorption spectrometry].
abstract: Among various procedures for the determination of thallium as a toxic element, micro-techniques by means of flameless AAS play an important role in hair analysis. Referring to two cases of T1-intoxication laboratory procedures, techniques and instrumentation are reported, which prove to be useful, sensitive, and fast. Considerations concerning sample preparation, contamination problems and compensation of spectral background effects by a duochannel spectrophotometer are discussed.
