Clinical experience (Browne, Beck, and McCallum, 1949) and rising certification figures by the Pneumoconiosis Medical Board show that there is a pneumoconiosis problem amongst Durham coalminers. Moreover, a study of large films, taken following routine mass miniature radiography (M.M.R.) at eight Durham pits (McCallum, 1952), suggested that at least 3 to 6% of miners at these pits had well mark...

Section 7(c) of the National Insurance (Industrial Injuries) Act (1946) states that "industrial death benefit (in this Act referred to as "death benefit") shall be payable to such persons as are hereinafter provided if the death of the insured person results from the injury", and death benefit has therefore been paid to relatives (under certain specified conditions) of those dying from coalwork...

Although rates of pneumoconiosis in coal miners have declined substantially in the United States since the passage of the Federal Coal Mine Health and Safety Act of 1969, new cases continue to occur, including cases of rapidly progressive disease. In contrast, Australia’s underground coal mining industry has reported few new cases of pneumoconiosis for more than 20 years. Mortality from coal wo...

Blood samples of miners heavily exposed to coal dust were examined for changes in glutathione S-transferase (GST) activity. Decreased GST activity was found in red blood cells of subjects with early stages of coal workers' pneumoconiosis (International Labour Office classification 0/1-1/2) when compared with control miners. At further progression of coal workers' pneumoconiosis (> or = 2/1), th...

inhalational lung diseases are among the most important occupational diseases. pneumoconiosis refers to a group of lung diseases result from inhalation of usually inorganic dusts such as silicon dioxide, asbestos, coal, etc. , and their deposition in the lungs. the resultant pulmonary disorders depend on the susceptibility of lungs; size, concentration, solubility and fibrogenic properties of t...
