One of the oldest industrial diseases, silicosis, results from exposures to respirable crystalline silica, also known as silica dust. Workers worldwide exposed to silica dust span a variety of industries from construction, mining, sandblasting, to masonry, and machinery. In the United States alone 1.7 million workers are exposed to crystalline silica, which can also lead to lung cancer, tuberculosis, and other chronic airway diseases [1]. This paper will examine the health effects of silica dust on the worker, discussing exposure paths, work groups affected, occupational safety measures, worker health policies, and compare these among the developed and developing world. Implementing worker safety programs, which include wearing Personal Protective Equipment (PPE) and health monitoring and developing exposure limits, can help mitigate the adverse health risks of working with silica dust. A comparison of the successes and limitations of several programs from around the world will show that strong national occupational safety programs can reduce the mortality and illness rates of silicosis due to occupational silica dust exposure. Without a strong national occupational safety program history shows that workers will remain unprotected until they rally together under tragedy to fight for safety. Before more workers suffer and die tragically and unnecessarily, global safety policy makers can take a lesson from history, examine and compare current programs, and implement strong national occupational safety programs that save lives.

Background and Objective: Silica dust is present in almost all mining operations and can cause various health problems such as silicosis in workers. The present study aimed to determine the total and respirable dust levels and the crystalline silica content of the soil in the breathing zone of workers in Iranian mines. Methods: This cross-sectional study was carried out in 2016-2017 on six Iranian silica mines. Dust sampling was performed according to the National Institute of Occupational Safety and Health (NIOSH) method No. 0600. The samples were collected from the respiratory zone of workers at 114 stations in different units of the mines. The silica content was measured using the standard NIOSH method No. 7601. The crystalline silica content in bulk samples collected from the soil was determined by using the X-Ray Diffraction (XRD) spectroscopy method. Results: The highest concentration of crystalline silica dust was 2.81±0.49 mg/m3 and was observed in the air of crushing unit of mine no. 6, and the lowest was 0.08±0.208 mg/m3 and was measured in the management/administration unit of mine no.1. The mean silica content in the solid surface of the mines was 91%. The total and respirable dust levels in all units of the mines except management/administration were higher than the permissible limit. The free silica content of all collected samples was substantially higher than the permissible limits, and in some cases, it was as much as 100 times above the standard level, which reflects the extremely high risk of working in these mines. Conclusion: Exposure of workers with crystalline silica dust in all units was higher than the standard recommended limits. It is imperative to adopt immediate measures based on technical, managerial, and personal protection solutions to reduce the exposure of workers to silica.

Abstract Following an earthquake occurred in the middle Italy in 2009, the involved territory hosted in ten years thousands of construction sites. The aim of this study is to assess the chemical exposure of the construction workers involved in the reconstruction of the city. To assess the exposure we collected 91 air samples to quantify the occupational exposure to airborne dusts and free crystalline silica dusts. Six construction companies joined the study and hosted the air sampling activities. We identified 4 work tasks: bricklayer and similar; scaffolder and carpenter; manual demolition; other tasks. Personal air sampling was performed by using the SKC AirCheck XR5000 sample pumps. Respirable dust and respirable crystalline silica dusts were collected by using a GS-3 Cyclones and 25 mm PVC filters; inhalable dust was collected by using a I.O.M. sampler and 25 mm PVC filters. The analyses were carried out by using gravimetric determination. Sampling time varied from 4 to 8 hours. The geometric mean values of inhalable dust concentration for the work tasks was: 3,65 mg/m 3 for scaffolder and carpenter; 18,16 mg/m 3 for manual demolition workers; 8,76 mg/m 3 for bricklayer and similar; 6,33 mg/m 3 for other work tasks. The geometric mean values of respirable dust concentration for the work tasks was: 0,67 mg/m 3 for scaffolder and carpenter; 0,92 mg/m 3 for manual demolition workers; 0,72 mg/m 3 for bricklayer and similar; 0,45 mg/m 3 for other work tasks. About the Crystalline Free Silica dust exposure, the average concentration in mg/m 3 was: 0,0038 for manual demolition workers, 0,0057 for scaffolder and carpenter, 0,004 for bricklayer and similar, 0,0035 for other tasks. The comparison of the results shows that manual demolition workers are exposed to considerably high levels of inhalable dusts, exceeding the ACGIH TLV-TWA limit of 10 mg/m 3 . About the respirable dust concentration, none of the work tasks dust concentration exceeded the ACGIH TLV-TWA limit of 3 mg/m 3 . Measurements of crystalline silica dust have shown levels below the threshold limit value of 0,025 mg/m 3 . This is in line with the average concentrations of respirable dust.
