Apr 13, 2022 · Exposure to a toxic rock dust appears to be "the main driving force" behind a recent epidemic of severe black lung disease among coal miners, according to the findings of a new study. Lawmakers have debated and failed to adequately regulate the dust for decades. The study, which examined the lungs of modern miners and compared them to miners ... Silicosis: A non-reversible lung disease. Acute silicosis: cough, weight loss, and fatigue presents in a few weeks or years of exposure to inhaled silica. Chronic Silicosis: appears 10 to 30 years after exposure, affects upper lungs and causes extensive scarring. Accelerated Silicosis: occurs within10 years of high-level exposure. Silicosis: A non-reversible lung disease. Acute silicosis: cough, weight loss, and fatigue presents in a few weeks or years of exposure to inhaled silica. Chronic Silicosis: appears 10 to 30 years after exposure, affects upper lungs and causes extensive scarring.Lung damage from silicosis is permanent, making prevention extremely important. Silicosis usually develops after ten or more years of exposure to silica at low levels. However, it can develop a lot sooner (even within a few weeks), if you breathe in high levels of silica. Breathing in silica dust is also associated with lung cancer, pulmonary ...Background: Silicosis is a progressive lung disease resulting from the inhalation of respirable crystalline silica. Lung transplantation is the only treatment for end-stage silicosis. The aim of this study was to analyze the survival experience following lung transplantation among patients with silicosis.The exposure to the crystalline silica at concentrations close to the current occupational exposure limit value does not exclude the risk of the following pathologies: silicosis, lung cancer ...
