Study Notes
Pollution
- Pollution is the introduction of harmful materials into the environment, these materials are called pollutants.
- Pollution can be categorized into different types: air pollution, water pollution, soil pollution, and plastic pollution.
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 two types: primary pollutants and secondary pollutants.
Primary Pollutants
- Primary pollutants have a direct effect on the environment and organisms, they also have an indirect effect on the environment by being involved in the formation of secondary pollutants.
- Primary pollutants can be controlled by controlling the man-made activities that cause pollution.
- Examples of primary pollutants include particulate matter (aerosols, soot, dust), hydrocarbons, sulfur dioxide, nitrogen oxide, and carbon monoxide.
Secondary Pollutants
- Secondary pollutants are highly reactive, particularly when photochemical agents are involved in their formation.
- They are difficult to control due to the complexity of the reactions involved in their formation.
- Examples of secondary pollutants include acid rain, photochemical smog, and peroxyacetyl nitrate (PAN).
Water Pollution
- Water pollution occurs when harmful, toxic materials are mixed up with water.
- Causes of water pollution include factory effluent, sewage, garbage dumping, oil spills, and volcanic eruptions.
Effects of Water Pollution
- Water pollution can damage crops, lead to the death of aquatic animals, and contribute to acid rain.
Controlling Water Pollution
- Ways to control water pollution include saving water, disposing of garbage properly, avoiding the dumping of chemicals, oil, and medicines into water, and planting trees.
Plastic Pollution
- Plastic pollution is the addition of plastic waste to landscapes and waterways.
- It is caused by the improper disposal of manufactured plastics.
- Plastic pollution is choking our oceans by creating plastic gyres, entangling marine animals, and poisoning our food and water supply.
Soil Pollution
- Soil pollution occurs when substances are added to the soil that change its physical, chemical, or biological properties, ultimately reducing soil productivity.
