Exposure to environmental hazards such as coal dust, silica dust, and asbestos may lead to pulmonary fibrosis or scarring of the lung tissue. With this condition the lungs become stiff and have less elasticity. What would happen to the total lung capacity and vital capacity under these conditions

The toal lung capacity and vital lung capacity would drastically reduced leading to ineffective function as a result of the lung cancer that developed from this desease.

Explanation:

Plumonary fibrosis is a lung disease that occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it more difficult for your lungs to work properly.

As more environmetal hazards like coal dust, silica dust accumulates in the lungs leading to this deseases, it would grow to a stage where the lungs would be totally damaged.

Most lung damage caused by pulmonary fibrosis can't be repaired, but medications and therapies can sometimes help ease symptoms and improve quality of life. For some people, a lung transplant might be appropriate.
