Study Notes
Air Pollution
- Definition: The presence of substances in the atmosphere that can cause harm to humans, animals, and the environment.
- Sources:
- Natural: volcanic eruptions, wildfires
- Human-made: industrial processes, vehicle emissions, fossil fuel combustion
- Pollutants:
- Particulate matter (PM): tiny particles that can cause respiratory problems
- Nitrogen oxides (NOx): contribute to smog and acid rain
- Sulfur dioxide (SO2): causes acid rain and respiratory issues
- Ozone (O3): a secondary pollutant formed from NOx and volatile organic compounds (VOCs)
- Health effects:
- Respiratory problems (asthma, COPD)
- Cardiovascular disease
- Neurological damage
- Environmental effects:
- Acid rain
- Climate change
- Ecosystem disruption
Water Pollution
- Definition: The contamination of water bodies, including rivers, lakes, and oceans.
- Sources:
- Agricultural runoff (fertilizers, pesticides)
- Industrial waste
- Sewage and wastewater
- Oil spills
- Pollutants:
- Chemicals (pesticides, heavy metals)
- Bacteria and viruses
- Nutrients (excess nitrogen and phosphorus)
- Health effects:
- Waterborne diseases (cholera, typhoid fever)
- Cancer and other health problems from chemical exposure
- Environmental effects:
- Habitat destruction
- Disruption of aquatic ecosystems
- Impact on aquatic life
Soil Pollution
- Definition: The contamination of soil, affecting its fertility and quality.
- Sources:
- Industrial waste
- Agricultural chemicals (pesticides, fertilizers)
- Mining and drilling activities
- Improper waste disposal
- Pollutants:
- Heavy metals (lead, mercury)
- Organic pollutants (PCBs, dioxins)
- Radioactive substances
- Health effects:
- Ingestion of contaminated soil particles
- Exposure to toxic substances through skin contact
- Environmental effects:
- Soil degradation
- Reduced fertility and crop yields
- Disruption of ecosystem processes
Noise Pollution
- Definition: Unwanted or excessive sounds that can cause harm to humans and wildlife.
- Sources:
- Transportation (aircraft, vehicles, trains)
- Industrial activities
- Construction and demolition
- Recreational activities (music, fireworks)
- Effects:
- Hearing loss and tinnitus
- Cardiovascular disease
- Stress and anxiety
- Disruption of wildlife behavior and habitats
Air Pollution
- Air pollution is the presence of substances in the atmosphere that can cause harm to humans, animals, and the environment.
- Natural sources of air pollution include volcanic eruptions and wildfires.
- Human-made sources include industrial processes, vehicle emissions, and fossil fuel combustion.
- Particulate matter (PM) is a pollutant that can cause respiratory problems.
- Nitrogen oxides (NOx) contribute to smog and acid rain.
- Sulfur dioxide (SO2) causes acid rain and respiratory issues.
- Ozone (O3) is a secondary pollutant formed from NOx and volatile organic compounds (VOCs).
- Air pollution can cause respiratory problems, cardiovascular disease, and neurological damage.
- Air pollution also contributes to acid rain, climate change, and ecosystem disruption.
Water Pollution
- Water pollution is the contamination of water bodies, including rivers, lakes, and oceans.
- Agricultural runoff (fertilizers, pesticides) is a source of water pollution.
- Industrial waste, sewage, and oil spills also contribute to water pollution.
- Chemicals (pesticides, heavy metals), bacteria, and viruses are common pollutants in water.
- Nutrients (excess nitrogen and phosphorus) can also pollute water bodies.
- Water pollution can cause waterborne diseases, cancer, and other health problems.
- Water pollution also leads to habitat destruction, disruption of aquatic ecosystems, and impact on aquatic life.
Soil Pollution
- Soil pollution is the contamination of soil, affecting its fertility and quality.
- Industrial waste, agricultural chemicals, mining, and drilling activities can pollute soil.
- Heavy metals (lead, mercury), organic pollutants (PCBs, dioxins), and radioactive substances are common soil pollutants.
- Soil pollution can cause ingestion of contaminated soil particles and exposure to toxic substances through skin contact.
- Soil pollution leads to soil degradation, reduced fertility, and crop yields, and disrupts ecosystem processes.
Noise Pollution
- Noise pollution is unwanted or excessive sounds that can cause harm to humans and wildlife.
- Transportation (aircraft, vehicles, trains), industrial activities, construction, and recreational activities generate noise pollution.
- Noise pollution can cause hearing loss, tinnitus, cardiovascular disease, and stress and anxiety.
- Noise pollution also disrupts wildlife behavior and habitats.
