Study Notes
Understanding Pollution
- Pollution is the introduction of harmful substances or products into the environment, causing damage to the ecosystem and human health.
Primary Air Pollutants
- Primary air pollutants are hazardous substances that are directly emitted into the atmosphere from a source, such as vehicle exhausts, industrial processes, or natural sources.
- Examples of primary air pollutants include:
- Carbon monoxide (CO)
- Nitrogen oxides (NOx)
- Sulfur dioxide (SO2)
- Particulate matter (PM)
- Volatile organic compounds (VOCs)
- Primary air pollutants are characterized by their direct release into the atmosphere, often in large quantities.
Secondary Air Pollutants
- Secondary air pollutants are formed in the atmosphere through chemical reactions involving primary air pollutants and other atmospheric components.
- An example of a secondary air pollutant is ground-level ozone (O3), which is formed through the interaction of NOx and VOCs in the presence of sunlight.
Air Pollution
- Air pollution is considered to be the presence of high levels of pollutants in the air that can cause harm to human health, the environment, or the climate.
- Air pollution can be classified into two main categories: indoor air pollution and outdoor air pollution.
Indoor and Outdoor Air Pollution
- Indoor air pollution refers to the presence of pollutants inside buildings, homes, or other enclosed spaces, often resulting from human activities, heating, or cooking.
- Outdoor air pollution, on the other hand, occurs in the ambient atmosphere, affecting larger areas and populations.
- Key distinguishing factors between indoor and outdoor air pollution include the source, concentration, and dispersion of pollutants.
