“…[ 12 ] Moreover it was shown that talc inhalation leads to granuloma formation, interstitial fibrosis and emphysema. [ 13 ] Our results did not show a significant reduction in most spirometric variables in the exposed group, except for FEF25-75 which is suggestive of an obstructive pattern of pulmonary diseases.…”

Background: Exposure to rubber production emissions can cause respiratory problems. There is some evidence that physical activity might have protective effects against respiratory obstruction. Aims: This study, was investigated the effect of physical activity on potential respiratory damages induced by the exposure to rubber production chemicals. Methods: This cross-sectional study was carried out during 2019 on the staff of a rubber manufacturing company in Khorasan, Iran. Employees of a rubber manufacturing company were recruited in this cross-sectional study ( n = 385), and were classified into exposed ( n = 266) and unexposed ( n = 119) groups. Baecke Physical Activity Questionnaire (BPAQ) was used to assess the level of physical activity. Logistic regression was used to evaluate the effects of exposure, physical activity and confounding variables on pulmonary function test (PFT) results. Results: Work, leisure time and total physical activity scores were significantly higher in exposure group compared with control group subjects. Although no significant differences were observed between the exposure and control groups in most spirometric parameters, FEF25-75 was significantly lower in the exposure group ( P = 0.035). Abnormal PFT was observed in 93 participants (24.2%) and in the multivariate model was significantly associated with exposure (OR = 1.80, CI95: 1.01-3.22) and age (OR = 1.08, CI95: 1.02-1.14) but not physical activity score. Conclusion: Exposure to rubber manufacturing chemicals nearly doubles the odds of abnormal PFT, and the self-reported level of physical activity had no protective effect against these occupational hazards.

“…Many mines worldwide are ‘contaminated’ with asbestos mineral tailings (35–40). Asbestos has been reported in a vermiculite mine in South Africa (41), and there are anecdotal reports of asbestos in other mines such as the iron and manganese mines in the Northern Cape province and in chrome/platinum mine tailings dumps (James I Phillips, NIOH, personal communication).…”

Occupational respiratory diseases in the South African mining industry

BackgroundCrystalline silica and asbestos are common minerals that occur throughout South Africa, exposure to either causes respiratory disease. Most studies on silicosis in South Africa have been cross-sectional and long-term trends have not been reported. Although much research has been conducted on the health effects of silica dust and asbestos fibre in the gold-mining and asbestos-mining sectors, little is known about their health effects in other mining sectors.ObjectiveThe aims of this thesis were to describe silicosis trends in gold miners over three decades, and to explore the potential for diamond mine workers to develop asbestos-related diseases and platinum mine workers to develop silicosis.MethodsMine workers for the three sub-studies were identified from a mine worker autopsy database at the National Institute for Occupational Health.ResultsFrom 1975 to 2007, the proportions of white and black gold mine workers with silicosis increased from 18 to 22% and from 3 to 32% respectively. Cases of diamond and platinum mine workers with asbestos-related diseases and silicosis, respectively, were also identified.ConclusionThe trends in silicosis in gold miners at autopsy clearly demonstrate the failure of the gold mines to adequately control dust and prevent occupational respiratory disease. The two case series of diamond and platinum mine workers contribute to the evidence for the risk of asbestos-related diseases in diamond mine workers and silicosis in platinum mine workers, respectively. The absence of reliable environmental dust measurements and incomplete work history records impedes occupational health research in South Africa because it is difficult to identify and/or validate sources of dust exposure that may be associated with occupational respiratory disease.

The Risk of Asbestos Exposure in South African Diamond Mine Workers

These findings indicate that diamond mine workers are at risk of asbestos exposure and, thus, of developing asbestos-related diseases. South Africa is a mineral-rich country and, when mining one commodity, it is likely that other minerals, including asbestos, will be accidentally mined. Even at low concentrations, asbestos has the potential to cause disease, and mining companies should be aware of the health risk of accidentally mining it. Recording of comprehensive work histories should be mandatory to enable the risk to be quantified in future studies.
