Review
Most recent studies have indicated that the incidence and prevalence of the mineral pneumoconioses have been declining as dust control has improved, This finding is particularly true for coal workers' pneumoconiosis, asbestosis, and silicosis. Although the present preoccupation with molecular biology and immunology has led to a spate of studies of the mechanisms involved in the development of these conditions, and although many advances have been made, no convincing complete elucidation of these mechanisms has evolved. Meanwhile, the "paratoxicologic fringe," supported by the National Institute of Occupational Safety and Health and the Environmental Protection Agency, has been presenting the notion that almost every naturally occurring or synthesized mineral ranging from aluminum to silica is a carcinogen. Much of the evidence produced by this consortium has been found wanting, especially in regard to the alleged hazards of talc, beryllium, and silica.

The occupational exposure, clinical findings, lung function and radiological characteristics of 51 workers in an antimony smelting plant are presented. The workers were exposed to the airbone dust containing a high concentration of antimony trioxide (up to 88%) and antimony pentoxide. A particular X-ray picture was characterized by numerous small opacities densely distributed in the middle and lower lung fields, opacities of p, pinhead type. Sporadically pq type was seen, but never r type nor massive fibrosis (pmf). The pneumoconiotic changes developed after at least one decade of work. Nothing particular in clinical findings and lung function could be distinguished from other types of simple pneumoconioses. This pneumoconiosis is called--antimoniosis. No systemic manifestation of antimony oxide intoxication was found, with the exception of skin changes, "antimony dermatosis".

Review
In developing countries, the incidence and prevalence of pneumoconioses are high and appear to be increasing. The rapid expansion of mining, mineral extraction, construction, and other industries places many new workers at risk each year. The hygienically poor working conditions often expose workers to high concentrations of respirable dust, so that pneumoconioses can develop with rapid progression after a short latency period. The health risk is increased by the high prevalence of tuberculosis in most of those countries. Accurate statistical data on occupational diseases in developing countries are rare. Although some prevalence data are available from cross-sectional studies, incidence figures and risk estimates are usually lacking because of the absence of reliable information about the size of the population at risk and exposure measurements. Some figures on pneumoconioses from countries in Africa, Asia, and South America are presented. To prevent pneumoconioses, hygienic conditions at the workplaces should be controlled and improved and appropriate dust standards developed. Medical surveillance of exposed workers should be organized. Finally, research in the field of pneumoconioses in developing countries should be promoted.
