Long exposure to dust can give rise to:

Answer

### Step-by-Step Solution:

1. **Understanding the Impact of Dust Exposure**: Long exposure to dust can have significant health implications, particularly for the respiratory system. Dust particles can irritate the lungs and lead to various respiratory issues.

2. **Inflammation of the Lungs**: One of the primary effects of prolonged exposure to dust is inflammation of the lung tissues. This inflammation occurs as the body’s immune response to the irritants present in the dust.

3. **Development of Fibrosis**: Chronic inflammation can lead to fibrosis, which is the proliferation of fibrous tissues in the lungs. This means that the normal lung tissue is replaced with scar tissue, which can impair lung function.

4. **Examples of High-Risk Environments**: Certain occupations, such as those in grinding and stone-breaking industries, expose workers to high levels of dust. These workers are at a greater risk of developing lung fibrosis due to their prolonged exposure.

5. **Consequences of Lung Damage**: The damage caused by fibrosis can lead to serious respiratory issues, reducing the lungs' ability to function properly and potentially leading to chronic respiratory diseases.

### Final Answer:
Long exposure to dust can give rise to inflammation of the lungs, leading to fibrosis and serious lung damage.
