Study Notes
Environment and Health
- Environmental health refers to the theory and practice of assessing, correcting, controlling, and preventing factors in the environment that can potentially affect the health of present and future generations.
Atmospheric Composition
- Nitrogen makes up 78.08% of the atmosphere.
- Oxygen makes up 20.95% of the atmosphere.
- Argon makes up 0.93% of the atmosphere.
- Carbon dioxide makes up 0.04% of the atmosphere.
Types of Air Pollutants
- Primary air pollutants are harmful substances emitted directly into the atmosphere, such as sulfur dioxide from factories.
- Secondary air pollutants are harmful substances formed in the atmosphere when primary air pollutants react with substances normally found in the atmosphere or other air pollutants, such as sulfuric acid.
Sources of Air Pollution
- Air pollution can be divided into anthropogenic (man-made) and natural sources.
- Examples of natural sources include dust storms and volcanic action.
Factors Contributing to Air Pollution
- Industrialization is a significant contributor to air pollution.
- The greenhouse effect is also a contributor, with primary greenhouse gases including water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
Catalytic Cycle
- Chlorine atoms can react with 100,000 ozone molecules before being removed from the catalytic cycle.
