Study Notes
Pollution
- Pollution is the introduction of harmful materials into the environment.
- Harmful materials are called pollutants.
Air Pollution
- Air pollution involves the presence of harmful substances in the air, often emitted from human activities like industrial processes and vehicle exhaust.
- Common pollutants include particulate matter, nitrogen oxides, sulfur dioxide, and ozone.
- Air pollutants are further divided into primary pollutants and secondary pollutants.
Primary pollutants
- Have a direct effect on the environment and organisms.
- Have an indirect effect by being involved in the formation of secondary pollutants.
- Can be controlled by controlling man-made activities causing pollution.
- Examples:
- Particulate matter like aerosols, soot, dust
- Hydrocarbons
- Sulfur dioxide
- Nitrogen oxide
- Carbon monoxide
Secondary pollutants
- Highly reactive when photochemical agents are involved in their formation.
- Difficult to control because understanding the reactions involved in secondary pollutants formation is difficult.
- Examples:
- Acid rain
- Photochemical smog
- Peroxyacetyl nitrate (PAN)
Water pollution
- When harmful toxic material are mixed up with water.
- Causes:
- Effluent from factories
- Water from sewerage
- Throwing garbage into water
- Oil spillage
- Volcanoes
- Effects:
- Damage crops
- Death of aquatic Animals
- Fertilizers
- Acid rain
- Control:
- Save water
- Throw garbage in garbage boxes
- Do not throw chemicals, oil, & medicine into water
- Plant trees
Plastic pollution
- The addition of plastic waste to the landscape and waterways.
- Caused by manufactured plastics that are not properly disposed of.
- Choking our oceans by making plastic gyres, entangling marine animals, and poisoning our food and water supply.
Soil pollution
- When substances are added to soil that change the physical, chemical, or biological properties of soil and reduce productivity.
