Study Notes
Air Pollution Overview
- Air pollution is a mixture of natural and man-made substances in the breathable air, causing negative health and environmental effects.
Air Pollution Episodes
- Meuse Valley, Belgium (1930): First recorded air pollution episode. The area was an industrial center with factories producing sulfuric acid, steel, and zinc. A thermal inversion trapped pollutants, resulting in 60 deaths.
- Donora, Pennsylvania (1948): A small industrial town, primarily reliant on a zinc manufacturing plant and iron/steel mills. A temperature inversion worsened air quality. 6,063 out of 14,000 residents fell ill. 17 died and 4 more died by Christmas Eve.
- Los Angeles "Smog" (1943-1944): Occurred in a dry and sunny climate. Hydrocarbons, nitrogen oxides, and photochemical smog contributed to pollution. Common symptoms included sore throats, runny noses, and watery eyes.
- London Smog (1952): A severe episode due to a temperature inversion. Coal fires increased sulfur dioxide and smoke levels. Residents experienced significant respiratory problems, darkness, and 4,000-8,000 deaths over a few days.
- New York City (1966): A smoggiest day in the city’s recorded history. Heat inversion was the cause of this incident. Pulmonary emphysema was a major cause of death.
- Kawasaki, Japan (1970): High levels of sulfur dioxide from sintering plants increased respiratory illnesses like asthma. City residents had to wear masks to cope.
- Chernobyl Accident (1986): A nuclear power plant accident released large amounts of radioactive substances, causing immediate and long-term health issues, including cancer and radiation sickness. An area of at least 8 tons of radioactive material contaminated the atmosphere beyond what previous atomic bomb detonations produced.
- Europe's Acid Rains: Industrialized areas like the Ruhr Valley released pollutants, such as sulfur dioxide, into the atmosphere resulting in acid rain damaging historical buildings and forests.
Temperature Inversion
- A reversal of the normal temperature gradient in the troposphere, where a cool layer of air sits below a warmer layer. This traps pollutants close to the ground, worsening air quality.
Types of Air Pollutants
- Hydrocarbons: Used in fuels (gasoline, natural gas, etc.) and manufacturing. Also present in plastics, paints, and other products.
- Sulfur Compounds: Sulfur dioxide and sulfuric acid, often from burning fossil fuels . Causes respiratory issues, acid rain, and damage to structures.
- Nitrogen Compounds: Commonly caused by fossil fuel combustion and agricultural practices (fertilizers, manure).
- Ozone and Oxidants: Formed when sunlight interacts with nitrogen oxides and volatile organic compounds, leading to photochemical smog.
- Organic Particles: A mixture of solids and gases like pollen, mold spores, microorganisms, dust, and insects.
- Inorganic Particles: Composed of various materials from natural sources (dust, sand) or industrial processes (metal production).
- Other Pollutants: Other gases, dust, smoke, and vapor are also major air pollutants.
Effects of Air Pollution
- Short-term Effects: Coughing, wheezing, eye/nose/throat irritation, headaches, dizziness, and fatigue are common.
- Long-term Exposure: Can lead to respiratory illnesses (asthma, emphysema), cardiovascular damage, harm to liver/spleen/blood, neurological problems, cancer, birth defects , or even death.
Sources of Air Pollutants
- Residential energy use for cooking or heating.
- Vehicle emissions.
- Power generation.
- Agricultural activities (fertilizers, manure).
- Waste incineration (burning waste).
- Industrial processes.
