Simply put: Dust isn’t just “dirty” – it’s an invisible health killer. Short-term exposure might just cause coughing, but long-term exposure can lead to irreversible lung diseases, and even death.
Many business owners think: “Workers inevitably cough after years on the job, they’ll get used to it.” But in fact, the damage dust causes to the human body is cumulative and irreversible, and many occupational diseases only emerge slowly after retirement.
1. How Dust Enters the Body
| Pathway | Description |
| Inhalation | The main route. Dust enters through the nose, throat, and trachea into the lungs. |
| Skin Contact | Dust adheres to the skin, potentially causing allergies, inflammation, or absorption through pores. |
| Eye Contact | Dust flies into the eyes, causing irritation, redness, and blurred vision. |
| Ingestion | Dust contaminates food or cigarettes, or is swallowed when hands aren’t washed before eating. |
2. Short-Term Health Effects (Acute Symptoms)
| Symptom | Description |
| Eye Irritation | Redness, tearing, itching; long-term may cause conjunctivitis. |
| Skin Allergies | Itching, rashes, dryness – especially from metal dust, fiberglass dust. |
| Respiratory Irritation | Itchy throat, coughing, sneezing, runny nose – like a cold that won’t go away. |
| Dizziness, Nausea | Certain chemical dusts (like solvent vapors) can cause toxic reactions. |
| Allergic Rhinitis | Long-term exposure triggers allergies; continuous sneezing in the morning. |
3. Long-Term Health Effects (Chronic Diseases)
| Disease Name | Description | Common Causing Dusts |
| Pneumoconiosis | Dust deposits in the lungs, causing fibrosis; breathing becomes increasingly difficult. Irreversible, incurable. | Silica (quartz), coal, asbestos, welding fumes |
| Chronic Bronchitis | Persistent airway inflammation; continuous cough, phlegm; severe cases cause breathing difficulty. | Wood dust, cotton dust, grain dust |
| Asthma | Dust triggers asthma attacks; chest tightness, wheezing, difficulty breathing. | Wood dust (especially hardwoods), chemical dust, flour |
| Lung Cancer | Certain dusts are confirmed or suspected carcinogens. | Asbestos, nickel, chromium, arsenic, welding fumes |
| Nasopharyngeal Cancer | Long-term inhalation of wood dust (especially in furniture) increases risk. | Wood dust |
| Skin Lesions | Long-term contact causes skin thickening, allergies, even cancer. | Arsenic, tar,某些 chemical dusts |
4. Particularly Hazardous Dust Types
| Dust Type | Hazard Description |
| Crystalline Silica (Quartz) | Most common and dangerous; causes silicosis. Common in stone cutting, glass grinding, foundries. |
| Asbestos | Confirmed carcinogen; causes asbestosis, lung cancer, mesothelioma. Banned in Taiwan but present in older buildings. |
| Welding Fumes | Contain heavy metals like manganese, chromium, nickel; may cause Parkinson’s-like symptoms, lung cancer. |
| Wood Dust | Hardwood dusts (oak, mahogany) are confirmed carcinogens for sinus cancer. |
| Lead Dust | Damages nervous and hematopoietic systems; especially harmful to children (carried home on work clothes). |
| Nickel, Chromium, Cadmium | Heavy metal dusts; may cause lung cancer, nasal cancer. |
5. Often Overlooked: Indirectly Exposed Groups
It’s not just operators; these people may also be affected:
| Group | Exposure Route |
| Office Staff | Dust drifts into offices or is brought back from the factory floor |
| Contractors/Maintenance | Short-term but high-concentration exposure |
| Business Owners | Daily tours of the factory, long-term accumulation |
| Employees’ Families | Dust carried home on work clothes |
