Determinants of chronic bronchitis and lung dysfunction in Western Australian gold miners.

Respiratory symptoms and lung function impairment in underground gold miners in ghana.

SUMMARY BACKGROUND This is the first study in Ghana in the Obuasi gold mines where the silica content of the respirable dust is 10%, less than in previously studied gold mines, with only 23% of the miners having ever smoked. OBJECTIVES The study was to assess the prevalence of respiratory impairment in the Ghanaian gold miner and to quantify the effects of the respirable dust on pulmonary fun...

Chronic bronchitis in miners and non-miners: an epidemiological survey of a community in the gold-mining area in the Transvaal.

Studies on the nature and aetiology of respiratory disability in Witwatersrand gold-miners free of radiological silicosis.

In an investigation into the cause of symptoms in gold-miners who have no radiological silicosis, the relationship of dyspnoea and physiological disturbances to dust exposure was examined. Forty-five subjects, aged 41 to 45 years, with normal chest radiographs and long service underground were chosen for study from the population of miners past and present. Thirty-four men only were tested, but...

  Background and aims   Low dose and long term exposure to inorganic, organic, irritant and allergic substances in workplaces can slowly and gradually cause chronic diseases such as chronic bronchitis ,asthma and pneumoconiosis. The purpose of this study is the exact determination of  lung diseases prevalence in Turquoise Miners and determination of associated factors in these diseases.   Metho...

Coal mining and chronic obstructive pulmonary disease: a review of the evidence.

The potential of coal mine dust to cause disabling pneumoconiosis has long been recognised, but research now suggests that pneumoconiosis is not the only respiratory hazard of coal mining.Over the last 30 years evidence has accumulated that miners also experience an excess of chronic obstructive pulmonary disease (COPD), and this has led the British Government to classify chronic bronchitis and...
