Conclusions It is concluded that occupational activities which involve exposure to 'dust and plant source particulate matter' such as stone grinding, mill and agricultural works affect the lung capacity and cardio-respiratory fitness of workers and the maximum deterioration of these parameters have been observed in the stone grinders

Abstract. Silicosis may be defined as the disease resulting from chronic occupational exposure to silica dust. Silica is primarily composed of quartz dust and has been classified since 2000 as a known human carcinogen by the U.S. government. Silicosis may lead to impairment of lung function resulting from fibrosis of the lungs.

National Institute for Occupational Safety and Health Summary Construction workers are ex-posed to hazardous dust when grinding or cutting mortar or ce-ment from between the bricks of old buildings. The National Insti-tute for Occupational Safety and Health (NIOSH) found that ex-posures could be reduced using tool-mounted local exhaust ven-

• Based on data from the SENSOR silicosis programs in Michigan, New Jersey, and Ohio for the period from 1993–2002, approximately 7% of confirmed silicosis cases for which duration of exposure was ascertained had less than 10 years of potential occupational exposure …

Humans . The use of 26 Al as a tracer and accelerator mass spectrometry has enabled safe studies of aluminium toxicokinetics with real exposure-relevant doses in humans. Aluminium bioavailability from occupational inhalation exposure is ~ 2% whereas oral aluminium bioavailability from water has been reported to be 0.1 to 0.4%.

Respirable silica dust exposure has long been known to be a serious health threat to workers in many industries. Overexposure to respirable silica dust can lead to the development of ...

Reducing workers' exposure to crystalline silica dust is currently a major challenge for granite manufacturing industries. In North America, occupational health regulations are becoming increasingly severe and demanding with respect to quartz dust particle exposure among workers. Of all granite transformation processes, dust control during polishing is the most difficult to realize. During ...

Cement Dust. Cement dust is an example of mineral dust that constitutes chemical components like silicon, calcium, aluminum, chromium, iron. 9–11 This dust is generated in different sections where cement production and processing occur, such as extraction of raw material, crusher, rotary kiln, cranes, mills, storage silos, packing area, etc. (Figure 1). 12, 13 Crystalline silica is a ...

Health hazards associated with exposure to elevated levels of mineral dusts depends on the type of dust, which will determine its toxicological properties, and hence health effects. Health effects from exposure to mineral dusts may become obvious only after long-term exposure. Health effects may appear after the exposure has ceased.

Potential Sources of Exposure. Lead dust from feed materials can become airborne during handling and transport (Figure 1). Lead dust that has settled on surfaces and equipment may become airborne due to vehicle traffic and cross-drafts. Possible Engineering and Work Practice Controls. Reduce vehicle speeds to minimize stirring up settled dust.

Silica has recently been in the news because this past August the US Occupational Safety and Health Administration (OSHA) proposed a new rule lowering the occupational limit from 0.1 mg/m3 (0.25 mg/m3 for the construction industry) to 0.05 mg/m3.1 The current standard was set in 1971. Although regulation of occupational exposures at the current ...

Workers cutting or grinding granite or sandstone had exposures exceeding the Irish occupational exposure limit (OEL) value of 0.1mg m –3 30 or 57% of the time, respectively. The highest 8-h time-weighted average reached a breathtaking 6mg m –3. The remarkable thing about this finding is that it is neither new nor unusual.

Exposure to flour dust and other organic materials can lead to serious respiratory disease such as asthma (Baker's asthma) respiratory sensitization, and allergies. Occupational asthma is a common disease in the UK with up to 3000 new cases diagnosed every year. Flour dusts can also cause and explosion. The chances of creating airborne flour dust increase greatly in large operations that use ...
