Black lung disease (BLD), also known as coal workers' pneumoconiosis, [1] or simply black lung, is an occupational type of pneumoconiosis caused by long-term inhalation and deposition of coal dust in the lungs and the consequent lung tissue's reaction to its presence. [2]
Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust, and is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs.
Pneumoconiosis is the general term for a class of interstitial lung disease where inhalation of dust (for example, ash dust, lead particles, pollen grains etc) has caused interstitial fibrosis. [ 1 ] [ 2 ] The three most common types are asbestosis , silicosis , and coal miner's lung . [ 3 ]
Crystalline silica, of course, is a leading cause of pneumoconiosis, or black lung, a dust-induced scarring lung disease that leads to the death of about 1,000 miners each year. And, yet, it is ...
The disease gets its name because dust inhalation causes scarring in the lung tissue, which turns black as the condition worsens.
OpEd: The federal Black Lung Program was enacted in 1969, just prior to the death of my grandfather, a Kentucky coal miner, from the disease. It’s not helping enough people.
Immunologically, disease is caused primarily through the activity of lung macrophages, which phagocytose dust particles after their deposition. These macrophages seek to eliminate the dust particle through either the mucociliary mechanism, or through lymphatic vessels which drain the lungs.
The Black Lung Benefits Act (BLBA) is a U.S. federal law which provides monthly payments and medical benefits to coal miners totally disabled from pneumoconiosis (black lung disease) arising from employment in or around the nation's coal mines. The law also provides monthly benefits to a miner's dependent survivors if pneumoconiosis caused or ...
