Exposure Assessment Strategies for Crystalline Silica Health Effects

摘要: Abstract Occupational exposure to dusts containing crystalline silica have long been associated with the induction of silicosis, a focal fibrosis pulmonary parenchyma. Since only dust that could penetrate gas exchange region lung, defined as respirable dust, produce pneumoconiosis such size-selective inlets were developed for air samplers restrict analyses fraction airborne dust. Analyses are reported in terms mass concentration, although case can be made associating hazard more closely surface area The hazards inhaling within mixtures also depend on properties coconstituents mixed aerosol, documented epidemiological studies miners. Other considerations affecting assessment strategies concerns about diseases other than silicosis may caused by contain...
