Detailed Solution
Download Solution PDFCombustion of fossil fuels:
- This refers to the burning of coal, oil, gas, and other fossil fuels.
- These activities are typically related to human processes such as powering industrial plants, generating electricity, heating homes, and fueling vehicles.
- When these fuels are burned, they release pollutants into the atmosphere, including carbon dioxide (a greenhouse gas), sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants can have detrimental effects on air quality, health, and the global climate
Volcanic gases:
- When a volcano erupts, it releases a variety of gases and particles into the atmosphere.
- These can include sulfur dioxide, carbon dioxide, and other pollutants. These substances can degrade air quality and are considered a natural source of air pollution.
Pollens:
- Pollens are tiny, microscopic particles released into the air by trees, flowers, grasses, and weeds for the purpose of plant fertilization.
- For some people, certain types of pollen can cause allergies and respiratory issues, thus representing a form of natural air pollution.
Wildfire by atmospheric temperature change:
- Wildfires, particularly those caused by natural events like lightning strikes or extreme heat, can produce large amounts of smoke and particulates that contaminate the air.
- This makes wildfires another significant source of natural air pollution..
