Occupational exposure to dusts containing crystalline silica have long been associated with the induction of silicosis, a focal fibrosis of the pulmonary parenchyma. Since only the dust that could penetrate to the gas exchange region of the lung, defined as respirable dust, could produce a ...
Inhalation is the primary route of exposure to crystalline silica dust.For any kind of dust,there are different particle sizes.When dust is inhaled,its point of deposition within the respiratory system is very much dependent upon the range of particle sizes present in the dust.It is the ...

Construction workers are at increased health risk due to exposure to respirable crystalline silica (RCS) dust. We examined differences in health risk among non-manual and manual employees in the construction industry. The participants were drawn randomly from the construction industry by targeting UK ...
DETERMINATION OF CONSTRUCTION WORKERS' EXPOSURE TO RESPIRABLE CRYSTALLINE SILICA AND RESPIRABLE DUST Background and Objectives: The dust raised in construction activities is one of the most important occupational hazard for health of construction workers. Due to the nature of the raw materials used, dus...
into the air or using a vacuum high efficiency filtered dust collection system to capture dust. In some operations, respirators may also be needed. Employers who follow Table 1 correctly are not required to measure workers’ exposure to silica from those tasks and are not subject to the PEL....
By Jerome E. Spear, CSP, CIH Silica dust is hazardous when very small (respirable) particles are inhaled. These respirable dust particles can penetrate deep into the lungs and cause disabling and sometimes fatal lung diseases, including silicosis and lun
Respirable crystalline silica is a highly prevalent occupational exposure and a recognized lung carcinogen. Most previous studies have focused on selected ...

Occupational silica dust exposure or silicosis; Evidence related to mechanisms that may account for the link between silicon and autoimmune diseases; Diseases with renal involvement; Systemic lupus erythematosus; Biologic mechanism of silica in autoimmune disease....
“Epidemiological studies reveal an association between exposure to crystalline silica dust and an increased probability of developing lung cancer. Administration of crystalline silica to rats by inhalation or intratracheal instillation also led to the development of lung tumours. Therefore, crystalline silic...
