    Study Notes

    What is Pollution?

    • Pollution is the act of releasing harmful or damaging substances into the environment, known as pollutants.
    • There are five recognized categories of pollution: air, land, water, noise, and light.

    Types of Pollution

    • Air pollution is caused by the release of harmful gases into the atmosphere, such as soot or ash from burning substances and toxic gases like carbon dioxide from fossil fuels.
    • Land pollution is defined by the presence of toxic substances in soil or litter, including litter, fertilizer runoff, oil spills, and raw sewage disposal.
    • Water pollution is caused by factors such as litter, fertilizer runoff, oil spills, and raw sewage disposal.
    • Noise pollution is caused by the noise of a busy environment, such as a city.
    • Light pollution is caused by the cumulative effect of many lights on the night sky, disrupting nocturnal animals' environments.

    Environmental Pollution

    • Environmental pollution is the damaging effect of human activity on Earth, specifically land, air, and water.
    • Examples of environmental pollution include air, water, and soil pollution.
    • Human activities, such as burning fossil fuels and releasing toxic gases, contribute to environmental pollution.

    Reducing Environmental Pollution

    • Using cleaner forms of energy can reduce air pollution.
    • Recycling products and goods can reduce waste and keep materials out of landfills.
    • Using green products, or natural products, can replace harmful chemicals and reduce pollution.

    Physical Pollution

    • Physical pollution occurs when materials or objects are introduced into the environment, causing toxicity or harm.
    • Examples of physical pollution include litter, such as incorrectly disposed of water bottles, and landfills.

    Landfills

    • Landfills are designated areas for trash disposal, lined with a waterproof barrier to prevent soil contamination.
    • Landfills contribute to pollution by releasing greenhouse gases and contaminating surrounding soil and land.

    Chemical Pollution

    • Chemical pollution is the release of harmful chemicals into the soil, air, or water by humans.
    • Examples of chemical pollutants include mercury, volatile organic compounds (VOCs), carbon monoxide, and sulfur dioxide.
    • Chemical pollutants can come from industrial waste, fertilizers, pesticides, and chemical factories.
    • Dioxin is a particularly harmful chemical pollutant that weakens the immune system and affects seed development in plants.

    Biological Pollution

    • Biological pollution consists of substances derived from nature that cause human harm.
    • Examples of biological pollutants include pollen, bacteria, and human fecal matter.
    • Biological pollutants can adapt to the environment and indicate contamination from humans.
