Study Notes

Air Pollution and Health Impacts

Low levels of air pollutants like ozone, sulfur oxides, nitrogen oxides, and particulate matter can irritate eyes and inflame the respiratory tract.
Air pollutants suppress the immune system, increasing susceptibility to infections.
Prolonged exposure during respiratory illnesses raises the risk of developing chronic diseases such as emphysema and chronic bronchitis.

Health Effects of Specific Pollutants

Sulfur dioxide and particulate matter constrict airways, impairing lung gas exchange and exacerbating conditions like emphysema and asthma.
Nitrogen dioxide also causes airway constriction and increases sensitivity to allergens like pollen and dust mites.

Children's Vulnerability to Air Pollution

Air pollution poses a greater health risk to children due to their developing lungs and higher metabolic rate, leading to increased oxygen and air intake.
A 1990 study indicated that over 80% of autopsied children in Los Angeles had early-stage lung disease.
Children exposed to higher concentrations of pollutants showed reduced lung growth; relocation to cleaner areas improved lung development.

Waste Management and Air Quality

Waste management processes aim to handle waste effectively to minimize environmental and health impacts.
Industrial smog is less problematic in developed countries due to regulations, but remains a significant issue in some developing regions.

Types of Air Pollutants

Hazardous Air Pollutants: Potentially harmful pollutants posing long-term health risks.
Photochemical Smog: Brownish-orange haze formed by sunlight-driven chemical reactions involving nitrogen oxides and hydrocarbons, most prevalent in summer.

Effects of Air Pollution

Air pollution can injure organisms, reduce visibility, and damage materials like metals and plastics.
Negatively affects the respiratory systems of animals, worsening conditions like chronic lung disease and cardiovascular issues.
Contributes to reduced agricultural productivity and can exacerbate environmental challenges like acid deposition and climate change.

Major Classes of Air Pollutants

Lead: A soft metal associated with health impacts such as cognitive decline and developmental issues, particularly in children.
Nitrogen Oxides (NOx): Gases from fuel combustion that harm plant growth and aggravate respiratory diseases. Nitrous oxide contributes to global warming and ozone depletion.
Sulfur Oxides: Gases formed from sulfur and oxygen, leading to acid deposition, material corrosion, and respiratory irritation. Key pollutants include sulfur dioxide and sulfur trioxide, which can form sulfuric acid in the atmosphere.
