“…Optimization of the procedure of biological materials for selenium determination (16) involved using a digestion mixture containing Na2Mo04; H2S04, and HC104. Wet-destruction of dry organic material in a closed quartz tube (17), and digestion in sealed, disposable polystyrene vessels (18) were advocated for certain samples. Low temperature plasma ashing was used in the analysis for phosphorus (19) and metallic elements (20).…”

In 25 random autopsies, chromium (Cr) and nickel (Ni) in lung tissue and regional lymph nodes were analysed by means of flameless atomic absorption spectrometry (AAS). The subjects originate from Bochum in the Ruhr District, which is defined as a particular pollution area with locally high Cr and Ni emissions. The subjects examined from Bochum (BO) and vicinity have Cr and Ni concentrations about 5 and 6 times higher than those in a previous series form Münster (MS) and vicinity (outside the particular pollution area), which is used for comparison purposes. BO and MS data showed an age-dependent increase of chromium and nickel in the lung, and in both data sets as well as in the combined, the Cr and Ni values showed extremely high correlations (r greater than 0.9). The Cr and Ni concentrations (BO) in lung (3.47 +/- 2.53 micrograms Cr/g, 1.09 +/- 1.43 micrograms Ni/g dry weight) and lymph node tissue (6.30 +/- 3.72 micrograms Cr/g, 1.00 +/- 0.58 micrograms Ni/g dry weight) do not show any correlation. The BO data contained four cases of bronchial carcinoma (all male), three of which showed pulmonary Cr and Ni concentrations that lie clearly above the predicted level. One case of bronchial carcinoma had extremely high Cr and Ni values; an occupational exposure as dental laboratory technician is taken into consideration.
