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 investigation in the Khurda District of Orissa demonstrated a reduction in respirable particulate mass following the application of a fine mist...
Oct 01, 2011 Oct 01, 2011 The aim of this study was to evaluate the effect of stone crushing industry on different foliar parameters of Shorea robusta and Madhuca indica which are two dominant broadleaved tree species of the forest concerned. Measurement of suspended particulate matter SPM, dustfall and gaseous pollutants in ambient air were done.

Sep 28, 2012 Stone quarrying is a form of land use method concerned with the extraction of non-fuel and non-metal minerals from rocks 1. It is usually done by open-cast method using rock drills, explosion of dynamite and use of other methods 2. Quarrying has environmental and health effects.
It is concluded from this research the particulate generated from stone crushing activities contain a significant amount of respirable particle. The amount of free silica in stone quartz is 85 to 97 percent that emission of particles effect to health workers. LEV has important effect in the removal of silica particles in stone crushing units.
Workplace dust exposure has long been identified as a cause of occupational lung disease. In India some 500 000 people work in the quarrying and processing of stone there are over 12 000 stone-crushing sites, which tend to be poorly regulated with very limited dust reduction measures in place.1 2 As part of a cross-sectional study to examine the effects of exposure to dust and respirable ...
vide crushed stone and dimension stone resources. The term crushed stone refers to the product resulting from the crushing of rocks such that substan-tially all faces are created by the crush-ing operation ASTM, 2000. The term dimension stone is generally applied to masses of stone, either naturally occur-ring or prepared for ...

The average value of total dust and respirable dust emission from stationary sources was 9.46 mgm 3, 1.24 mgm 3 respectively, showing that 13.8 of total dust is respirable. The efficiency of local exhaust ventilation LEV to control of particles inside of industrial units was greater than 99. It is concluded from this research the particulate generated from stone crushing activities contain a
May 01, 2008 In India some 500 000 people work in the quarrying and processing of stone there are over 12 000 stone-crushing sites, which tend to be poorly regulated with very limited dust reduction measures in place.1 2 As part of a cross-sectional study to examine the effects of exposure to dust and respirable crystalline silica on lung development, we set out to characterise the exposure to particulate matter of a group of workers at a stone-crushing
Background Dusts containing crystalline silica are generated in mining, construction, glass, granite and concrete production industries. The association between exposure to low levels of concrete dust containing crystalline silica and reduction in lung function, was evaluated in a cross-sectional study.

Crystalline silica. The most hazardous eruptions are those generating fine-grained ash with a high content of free crystalline silica, as this mineral has the potential to cause silicosis a chronic lung disease resulting in scarring damage to the lungs and impairment of their function.Silicosis is primarily an occupational disease associated with occupations such as stone-cutting, road and ...
