Title Studies on anthracosis of human lung - Wave-dispersive X-ray fluorescence analysis of particulate pollutants in the lung
Bibliographic information Oct. 1984, Vol.11, No.4, p.349-357. Illus. 16 ref.
Abstract In order to estimate lung pollution, elemental analysis of the mineral material in particulate pollutants (PP) in the lung was carried out. The PP were extrcted by alkali digestion from 14 autopsy cases and one lobectomized lung cancer case and were analyzed with a wave-dispersive X-ray fluorescence analyzer. High levels of Si (14.6% of the mineral material), Ca (10.8%), Fe (7.4%), Al (4.6%) and trace amounts of several heavy metals (Cu, Mn, Cr, Ni, Ti) were found. They were probably attributable to soil-derived pollutants in the air. Alkali digestion and X-ray fluorescence techniques have advantages over other methods in the easiness of the procedure.
