Respiratory Symptoms and Pulmonary Function Among Artisanal Stone-Crushers and Wood Sawyers: A Cross-Sectional Study in Lubumbashi (DR Congo) T. Kayembe-Kitenge 6 x
Pulmonary involvement in ankylosing spondylitis 739 niques was significantly related to the disease dura- tion, thoracic mobility, and inflammatory activity defined by ESR, haptoglobin, orosomucoid, and IgA. The strongest correlations were observed be-tween lungvolumehoracic mobility (Table 3, Fig. 1). The thoracic mobility was also related to ESR (r=-0.47, p<0-01), haptoglobin (r=-0.42,

05-03-2018· Occupational exposure to dust is a major health and safety concern for workers in developing countries. Such laborers are often exposed to dust without being aware of its threat to their health. In the process of crushing stone, mineralogical materials are released into the environment. The material includes dust, fumes, ashes or other industrial waste which may constitute toxic elements.
Objectives Chronic obstructive pulmonary disease and silicosis are associated with exposure to crystalline silica. We determined the exposure to respirable crystalline silica and estimated exposure–response relationships between cumulative exposure and pulmonary function in outdoor rock drillers. Methods 136 rock drillers and 48 referents were recruited from three heavy construction ...

Pulmonary function test were recorded on 50 subjects. Statistical analysis amongst the stone crusher workers was carried out by Analysis of Variance (ANNOVA) test. Results: It was concluded from this study that pulmonary function test decreases as duration of exposure to silica dust increases.
Among the present workers, pulmonary function testing revealed the combined type of functional impairment in 1 (0.5%), restrictive type in 13 (7.1%), and obstructive type of functional impairment in 17 (9.2%) subjects. Conclusion: The high prevalence of respiratory morbidity in ex-workers as compared to current workers can be attributed to the out-of-the-job healthy workers' effect.

Abstract Respirable crystalline silica dust generated during stone crushing operations has been linked to chronic lung disease and increased risk of tuberculosis. In India, most stone crushing mills operate without any dust control or containment systems. This nvestigation in the Khurda District of Orissa demonstrated a reduction in respirable particulate mass following the application of a ...

15-09-2014· A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizes will have to be selected overloading the secondary crusher.
lung function testing (spirometry), which involves breathing into a machine called a spirometer to assess how well your lungs are working; A test for TB may also be recommended because you're more likely to get TB if you have silicosis. Treating silicosis. There's no cure for silicosis because the lung damage can't be reversed.
Methods. Two hundred seventy two stone crushing workers and 123 nonexposed workers were analyzed in terms of occupational and personal histories, radiological findings, and pulmonary function test (PFT) results including slow vital capacity (FVC), forced vital …
