In this article, you will learn about the different types of pollution, the affect they have on human and environmental health, as well as the ways people can reduce these types of pollution.
Main Types of Pollution
Air Pollution
Air pollution involves the release of harmful gases and particles, causing respiratory issues and damaging natural habitats.
Water Pollution
Water pollution contaminates lakes and oceans, threatening aquatic life and disrupting clean water supplies for people.
Soil Pollution
Soil pollution degrades land quality, affecting agriculture and leading to long-term environmental damage.

Sources of Air Pollution
Anthropogenic (man-made): vehicle emissions, heating homes, industrial manufacturing, power generation, chemical production, agricultural activities, waste management
Natural: wildfires, volcanic eruptions, dust storms, dust and wind in general
Common Air Pollutants
Particulate matter: Abbreviated PM, these are small specks of dust that can originate from agricultural and industrial activities. PM2.5, particulate matter with a diameter of 2.5 micrometers or less, is especially harmful as it is extremely small and can infiltrate deep into the lungs and even bloodstream.
Other air pollutants: ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, lead
Effects of Air Pollution
On Humans: Short term exposure to air pollution can lead to respiratory irritation, while long term exposure can lead to heart disease, respiratory infections like bronchitis, as well as lung cancer
On Environment: Air pollution can lead to acid rain, which can damage buildings, increase water and soil acidity, and also lead to the release of toxic heavy metals from the soil in a process known as heavy metal leaching.
Water Pollution
Explore major types of pollution and discover practical strategies to protect our environment and health.
Sources of Water Pollution
Sewage, industry, agriculture, urban runoff
Saltwater Intrusion: movement of seawater into freshwater aquifers, happens near the coast when pumping water from the ground results in the water table lowering at that point, allowing seawater from the ocean to flow in
Common Water Pollutants
Microorganisms, (e.g., E. coli, Giardia, and noroviruses), inorganic chemicals (e.g., lead, arsenic, nitrates, and nitrites), organic chemicals (e.g., atrazine, glyphosate, trichloroethylene, and tetrachloroethylene), disinfection byproducts (e.g., chloroform)
Effects of Water Pollution
Eutrophication(excess levels of nitrogen and phosphorus cause unsustainable algae blooms in water), disease, infant mortality
Soil Pollution
Explore major types of pollution and discover practical strategies to protect our environment and health.
Sources of Soil Pollution
Agriculture(pesticides and fertilizers), mining, landfills, wastewater, acid rain, industrial waste, construction
Common Soil Pollutants
Petroleum hydrocarbons, pesticides, lead, heavy metals(arsenic, beryllium, cadmium, chromium, copper, nickel, lead and mercury)
Effects of Soil Pollution
Soil Salinization(increase in soil salinity): caused by mineral weathering, gradual withdrawal of the ocean, or by human process such as road salt or irrigation, salts may accumulate in dry regions(no rain to flush soil)
Consequences of soil salinity- Damage to infrastructure, detrimental effects to plant yield, Reduction in water quality for users, increased metal leaching, sedimentation problems

“Impaired” means that the water is too polluted for swimming, fishing, recreation or drinking
