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] It is common in coal miners and others who work with coal.
Although it has been defined as an extension of pneumoconiosis, there is no scientific evidence for a similar disease related to volcanic silica particle exposures. [8] Subsequently, the word was used in Frank Scully's puzzle book Bedside Manna, after which time, members of the N.P.L. campaigned to include the word in major dictionaries. [9] [10]

The disease gets its name because dust inhalation causes scarring in the lung tissue, which turns black as the condition worsens.
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 ...
Lung cancer is the most diagnosed and deadliest cancer worldwide, with 2.2 million cases in 2020 resulting in 1.8 million deaths. [3] Lung cancer is rare in those younger than 40; the average age at diagnosis is 70 years, and the average age at death 72. [2] Incidence and outcomes vary widely across the world, depending on patterns of tobacco use.
OpEd: We are concerned that too much of the rule is reliant on infrequent and unsupervised coal operator dust sampling and self-audits of changing dust conditions in the mines.
For uncomplicated silicosis, chest x-ray will confirm the presence of small (< 10 mm) nodules in the lungs, especially in the upper lung zones. Using the ILO classification system, these are of profusion 1/0 or greater and shape/size "p", "q", or "r". Lung zone involvement and profusion increases with disease progression.
