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.
