    Study Notes

    Environmental Pollution

    • Environment encompasses all physical and biological elements impacting organism survival, growth, development, and reproduction.
    • Biosphere includes the atmosphere, hydrosphere, and lithosphere. It encompasses the entire Earth, including all living and non-living components.

    Types of Pollution: Air Pollution

    • Air pollution is the disruption of atmosphere's normal composition by pollutants (natural or man-made).

    • Causes:

      • Greenhouse gases (e.g., CO₂, CH₄, CFCs, N₂O) absorb infrared radiation, trapping heat.
      • Sulphur oxides (SOx) and nitrogen oxides (NOx). These react with water in the atmosphere to form acid rain.
      • Particulate matter (SPM): solid or liquid particles (less than 10µ size) dispersed in air from combustion, industry, or natural sources (e.g., dust, smoke, soot).
      • Release of gases from various sources: burning fuel, industry emissions, deforestation, fertilizers, etc.
      • Various other chemicals like CFCs, N₂O, etc.

    • Effects:

      • Acid rain: damages plants, forests, and crops; harms aquatic life.
      • Global warming: causes temperature increase, desertification, changes in rainfall patterns.
      • Respiratory problems: lung diseases in humans.
      • Animal harm: killed and destroyed wildlife, respiratory and skin issues.
      • General damage: Corrosion of metals and structures, negative impacts on cultural heritage sites.

    Water Pollution

    • Adverse changes in water composition making it unsuitable for use.
    • Causes:
      • Agricultural runoff carrying fertilizers and pesticides.
      • Animal husbandry waste.
      • Pathogenic organisms (bacteria, viruses) from sewage.
    • Effects:
      • Waterborne diseases (cholera, typhoid).
      • Harm to aquatic life.
      • Eutrophication (excess nutrients lead to algal blooms).
      • Harm to humans and other organisms.

    Soil Pollution

    • Deterioration of land surface, affecting its quality and productivity.
    • Causes:
      • Excess fertilizers that harm quality.
      • Pesticides and herbicides that harm soil organisms and contaminate soil.
    • Effects:
      • Harm to living organisms and decrease in soil fertility.
      • Various diseases through contact or consuming.

    Noise Pollution

    • Unwanted, irregular, or unpleasant sounds generated by vibrations, causing noise pollution.
    • Causes:
      • Vehicles (lorries, cars, buses).
      • Industrial activities.
      • Domestic appliances.
      • Various festivals or celebrations.
    • Effects:
      • Hearing loss in humans.
      • Physiological problems (heart conditions, stress, sleep).
      • Negative impacts on animals (disrupted biological cycles).

    Biological Magnification

    • A process where levels of toxic substances increase as they move up the food chain.
    • Example: DDT in ecosystems. This is a concern for top predators in food chains.
