Understanding Pneumoconiosis: Causes, Symptoms, and Prevention
Pneumoconiosis is a group of lung diseases caused by the inhalation of dust particles—most commonly from coal, silica, or asbestos—over a long period of time. The condition primarily affects workers in mining, construction, manufacturing, and other industrial settings where fine dust exposure is frequent.
Once inhaled, these dust particles settle in the lungs, causing inflammation, scarring (fibrosis), and reduced lung function. Pneumoconiosis develops slowly and can lead to chronic respiratory problems, making it one of the most serious occupational lung diseases.
What Is Pneumoconiosis?
The term “pneumoconiosis” comes from Greek words meaning “dusty lungs.” It is classified as an occupational lung disease, as it results from long-term workplace exposure to airborne mineral dust.
The condition is not contagious but is progressive — meaning it worsens over time, even after exposure stops. The damage caused to lung tissue is usually permanent.
Types of Pneumoconiosis
There are several types of pneumoconiosis, depending on the type of dust inhaled:
1. Coal Worker’s Pneumoconiosis (CWP)
Also called “Black Lung Disease”, this type occurs from prolonged exposure to coal dust.
Common in coal miners.
Causes black-colored deposits and scarring in lung tissues.
In advanced stages, may lead to progressive massive fibrosis (PMF).
