Pneumoconiosis is a lung condition caused by the inhalation of airborne particles that can damage lung tissue. This is mainly seen with the inhalation of dust from coal (coal workerâs pneumoconiosis), asbestos (asbestosis), silica (silicosis) and beryllium (berylliosis). It is usually due to occupational exposure.
Learn About Silicosis. Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe. Key Facts. There are three types of silicosis: acute, chronic, and accelerated. It occurs in workers from mines, foundries, sandblasting, and glass manufacturing. About 2 million US workers remain potentially exposed to occupational silica.
