Normal values for arsenic and selenium concentrations in human lung tissue

Normal values and ranges were determined for arsenic and selenium concentrations in lung and hilus tissue. The study group consisted of 50 deceased persons, who were examined by autopsy at the Institute for Pathology of the University of Erlangen-Nuremberg. Taking into consideration topographic-anatomical criteria, samples were taken of each lung lobe and the hilar lymph nodes. The dried tissue was analyzed using by means of hydride atomic absorption spectrometry after wet-oxidative digestion. Normal values ranged for the arsenic concentrations from
