The correct answer is B. Coal miners.
Black lung disease is a serious lung disease caused by inhaling coal dust. It is also known as coal workers’ pneumoconiosis (CWP). Black lung disease is a progressive disease, which means it gets worse over time. There is no cure for black lung disease, but there are treatments that can help to manage the symptoms.
The main risk factor for black lung disease is exposure to coal dust. Coal dust is a fine, powdery substance that is produced when coal is mined. Coal dust can be inhaled into the lungs, where it can cause inflammation and scarring.
Other risk factors for black lung disease include:
- Smoking
- Age
- Family history of black lung disease
- Working in a dusty environment
Symptoms of black lung disease can vary depending on the severity of the disease. Some people with black lung disease may not have any symptoms at all. Others may experience symptoms such as:
- Shortness of breath
- Cough
- Chest pain
- Fatigue
- Weight loss
- Loss of appetite
- Wheezing
- Hoarseness
If you are exposed to coal dust, it is important to take steps to protect your lungs. These steps include:
- Wearing a respirator when working in a dusty environment
- Getting regular medical checkups
- Quitting smoking
- Eating a healthy diet
- Exercising regularly
If you have any concerns about black lung disease, talk to your doctor.
