Additional Physical Format: Online version: Pneumoconiosis in Appalachian bituminous coal miners. [Washington]: [U.S.G.P.O.], [] (OCoLC)   RECENT FINDINGS: The latest research shows that the prevalence of pneumoconiosis, including progressive massive fibrosis, continues to increase, especially in central Appalachia. Contributing factors may include mining of thin coal seams or cutting rock to access coal, which may expose miners to coal mine dust with a higher content of silica Cited by: 3. The prevalence of pneumoconiosis among working and nonworking miners in the Appalachian bituminous coal fields, and among working miners and nonminers and their respective wives in two West Virginia communities was surveyed from to Questionnaires were used to obtain medical, occupational, and smoking histories. Chest roentgenograms, ventilatory pulmonary function . Objectives Epidemiological reports since have documented increased prevalence and rapid progression of pneumoconiosis among underground coal miners in the United States. To investigate a possible role of silica exposure in the increase, we examined chest x-rays (CXRs) for specific abnormalities (r-type small opacities) known to be associated with silicosis lung pathology.

Objectives The natural history of coal workers’ pneumoconiosis (CWP) after cessation of exposure remains poorly understood. Methods We characterised the development of and progression to radiographic progressive massive fibrosis (PMF) among former US coal miners who applied for US federal benefits at least two times between 1 January and 31 December 27 Laney AS et al.

  In the mids, doctors participating in this program alerted federal authorities to the resurgence of black lung among coal miners in Appalachia. [C] Michael Suilivan/Science Source Caption: In , shortly after the Coal Act went into effect, PMF affected nearly % of coal miners with 25 or more years of underground mining tenure. in the central Appalachian bituminous coal mining region including eastern Kentucky, southwestern Virginia, and West Virginia, as noted in Fig. 1 [3, 5, 13–17]. A study found that the national prevalence of dust is the sole cause of pneumoconiosis in coal miners. Thus, epidemiological studies which assess correlates of. The National lnstitute of Occupational Safety and Health of the US public Health Service recently completed the first round of a large field study to determine the prevalence of coal workers, pneumoconiosis in working US coal miners. Between October and July a total of 9, miners from 29 bituminous and 2 anthracite mines were examined. This is a continuation of a previous study by LIEBEN et al. [this Bulletin, , v. 37, ] which covered pneumoconiosis in the central Pennsylvania bituminous coal mines. The present investigation concerns the western coal field and follows the pattern of the previous study. Radiological examination revealed pneumoconiosis in 11%: of working miners.
