Study Notes
Sources of Particulate Matter (PM)
- Combustion engines, solid-fuel combustion for energy production in households and industry, and other industrial activities (building, mining, manufacture of cement, ceramic and bricks, smelting)
- Industrial activities: building, mining, manufacture of cement, ceramic and bricks, smelting
Diseases of the Respiratory System Caused by Inorganic Dusts
- Pneumoconiosis: a chronic respiratory disease caused by long-term inhalation of dust
- Characterized by chronic bronchitis and progressive pulmonary emphysema, accompanied by pulmonary heart (hypertrophy and failure of the right ventricle) and circulatory insufficiency
- Types of dust diseases:
- Collagen dust disease: permanent damage of the structure of pulmonary alveoli and collagenic fibrosis (silicosis, asbestosis, talc and aluminium pneumoconiosis)
- Non-collagen dust disease: marginal growth of collagen fibres or cellular infiltration without any alteration in the alveoli structure in the lungs (barytosis, siderosis, tin-oxide pneumoconiosis)
Silicosis
- Respiratory disease caused by breathing in (inhaling) silica dust
- Found in most rock beds, forms during mining, quarrying, tunnelling, and working with certain metal ores
- Types of silicosis:
- Simple chronic silicosis: results from long-term exposure (lasting longer than 20 years) to low amounts of silica dust
- Accelerated silicosis: occurs after exposure to larger amounts of silica over a shorter period of time (lasting from 5 to 15 years)
- Acute silicosis: results from short-term exposure to very large amounts of silica
Coal Worker's Pneumoconiosis (Anthracosis/Black Lung/Caplan Syndrome)
- Chronic lung disease characterized by deposits of coal dust in the lungs and formation of black nodules in the bronchioles
- Results in focal emphysema
- Affects coal miners, aggravated by cigarette smoking
Asbestosis
- Inflammation and fibrosis of the lung caused by inhaling asbestos dust
- Increases the risk of cancer diseases (lung cancer, bronchial cancer) by four times, and pleural mesothelioma by almost a thousandfold

- Natural: living organisms, natural environments
- Industrial: food processing, industries, laboratories
- Building technologies: air conditioning systems, water supplies
Health Effects of Bioaerosol Exposure
- Related to the size of particles and site of their deposition
- Can range in infectivity, toxicity, and allergenicity depending on various process-specific factors

Air Quality Index (AQI)
- Values: 0-50 (good), 51-100 (moderate), 101-150 (unhealthy for sensitive groups), 151-200 (unhealthy), 201-300 (very unhealthy)
- Recommendations for limiting outdoor exertion and activity based on AQI values

- Worldwide ambient air pollution accounts for:
- 29% of all deaths and disease from lung cancer
- 17% of all deaths and disease from acute lower respiratory infection

- 25% of all deaths and disease from ischaemic heart disease
- 43% of all deaths and disease from chronic obstructive pulmonary disease
