Abstract

|
This study was analysis of α-quartz in the 37 worker´s lung died of coat workers´ pneumoconiosis(CWP) and in the 9 normal´s lung by Fourier transform infrared spectrophotometer.
The results were as follows :
1. The dried lung weight percents in wet lung weight were 24.4%, 25.4%, coal workers´ pneumoconiosis and normal lungs, respectively. Ash weight percents in dried lung weight were 7.7%, 5.0%, coal workers´ pneumoconiosis and normal lungs, respectively.
2. The precision (as of coefficient of variation) for the α-quartz determination were 2.6% in standard quartz (ranged from 9.9 to 198.0 ㎍) and 3.7% in ashed lung samples. 3. The characteristic α-quartz absorption spectra in lungs of CWP were only shawn by LTA ashing.
4. Geometric mean of α-quartz concentration in CWP lung was 173㎎/100g dried lung.
5. The concentrations of α-quartz in Korean CWP lungs were similar to those of foreign coal miner´s lungs.
