    Study Notes

    Pollution

    • Pollution is the introduction of harmful materials into the environment, damaging the quality of air, water, and land.
    • Sources of pollution include natural pollution (e.g., volcanoes, thunderbolts, storms) and industrial pollution (human activity).

    Chemical Pollution

    • Chemical pollution refers to the presence or increase of chemical pollutants in the environment, not naturally present or exceeding natural background values.
    • Most chemical pollutants are man-made, resulting from various activities using toxic chemicals.
    • Chemical pollutants can exist in gaseous, liquid, and solid states, characterized by their efficacy, toxicity, or explosive potential.
    • Effects of chemical pollution include:
      • Exposure to high amounts and accumulation of chemicals in the body, leading to serious diseases.
      • Consuming poisonous food, drinking contaminated water, or breathing contaminated air.
      • Chemicals can react with tissues, change organ structure and function, cause abnormal growth, or bind with genetic material, leading to cancer.

    Types of Chemical Pollution

    • Inorganic pollutants: released from mining, industry, transportation, and urban activities.
    • Organic pollutants: used in industry, medicine, and daily life, causing pollution through exposure to drugs, cleaning products, solvents, fuels, paints, inks, preservatives, and pesticides.
    • Nuclear (Radiation) pollutants: leakage of radioactive materials into the environment, causing hidden and visible damage to the body.

    Biological Pollutants

    • Biological pollutants: living organisms (bacteria, fungi, viruses) in the environment, causing disease through contaminated food, water, and air.

    Industrial Pollutants

    • Industrial pollutants are divided into three types:
      • Solid pollutants (e.g., dust from cement industry)
      • Liquid pollutants (e.g., chemical solutions in waterways)
      • Gas pollutants (e.g., harmful smoke and gases)

    Environmental Pollution

    • Environmental pollution: any undesirable change in physical, chemical, or biological characteristics of the environment, causing harm to life or property.
    • Types of environmental pollution include:
      • Water pollution
      • Air pollution
      • Land pollution
      • Noise pollution

    Water Pollution

    • Water pollution: alteration of water's physical, chemical, or biological characteristics, making it unsuitable for designated use.
    • Most water pollution is man-made, but can also occur naturally through soil erosion, animal waste, and mineral leaching from rocks.

    Air Pollution

    • Air pollution: introduction of pollutant materials into the air, harming human health and the environment.
    • Causes of air pollution include:
      • Burning of fossil fuels
      • Automobiles
      • Agricultural activities
      • Factories and industries
      • Mining activities
      • Domestic sources
      • Smoking

    Land Pollution

    • Land pollution: degradation of the earth's land surfaces, both above and below ground level.
    • Causes of land pollution include:
      • Accumulation of solid and liquid waste products, contaminating groundwater and soil.
    • Effects of land pollution include:
      • Harm to human body through ingestion of toxic waste and contaminants.
      • Disposal of hazardous radioactive wastes contributing to land contamination.
      • Chronic respiratory disease, lung cancer, heart disease, and brain damage.
