Recent British studies have confirmed initial interim results concerning the relationship between CWP and dust exposure. Incidence of CWP was found to be related primarily to total (mixed) respirable dust, with the curve approaching zero incidence close to 2 mg/m, and rising increasingly steeply with increasing dust level. The problem of the role of quartz in the causation of CWP has not been resolved, though there is an indication that miners experiencing higher levels may be at additional risk. Problems also remain over the identification of miners susceptible to CWP, and in the causation of massive fibrosis. The recent PFR research has thrown some light on this latter topic; the main conclusion remains, though, that to prevent PMF one must prevent simple CWP. Results from the National Coal Study support the view that the U.S. mining environment is similar to that of the British. As a consequence it appears that the current Federal standard will drastically reduce the level of CWP, both simple and complicated. Whether all pneumoconiosis will be eliminated is a question that remains to be answered. Research is continuing with this aim.
