The three major types of pollution are air pollution, water pollution, and land pollution. Sometimes, air pollution is visible. A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible.

The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. Microscopic pollutants in the air can slip past our body’s defences, penetrating deep into our respiratory and circulatory system, damaging our lungs, heart and brain.

Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather).

The two types of air pollutants are primary pollutants, which enter the atmosphere directly, and secondary pollutants, which form from a chemical reaction.

On Days when High Particle Levels are Expected, Take these Extra Steps to Reduce Pollution:

1. Reduce the number of trips you take in your car.
2. Reduce or eliminate fireplace and wood stove use.
3. Avoid burning leaves, trash, and other materials.
4. Avoid using gas-powered lawn and garden equipment.

Recycling and reusing items is one of the easiest methods to help teach kids how they can help with pollution. When it comes to teaching children about water pollution, Ocean Pollution Activities and Ocean Pollution Sensory Bins are perfect.

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

Ways to Reduce Air Pollution

• Riding a bike or walking instead of driving.
• Taking a bus or carpooling.
• Buying a car that has greater fuel efficiency.
• Turning off lights and appliances when they are not in use.
• Using energy efficient light bulbs and appliances.
• Buying fewer things that are manufactured using fossil fuels.

The different types of pollution include:

• Air pollution.
• Water pollution.
• Soil pollution.
• Radioactive pollution.
• Noise pollution.

Most ocean pollution begins on land. Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.

What Are the Different Types of Water Pollution?

• Chemical pollution. The most common type of water pollution, chemicals can infiltrate both underground water sources and those sitting on the Earth’s surface.
• Groundwater pollution.
• Microbiological pollution.
• Nutrient pollution.
• Oxygen-depletion pollution.
• Surface water pollution.

Air Pollutants

• Carbon Monoxide.
• Lead.
• Nitrogen Oxides.
• Ozone.
• Particulate Matter.
• Sulfur Dioxide.
• Other Air Pollutants.

Air pollution is a mix of hazardous substances from both human-made and natural sources. It contains most of the elements of human-made air pollution: ground-level ozone, various forms of carbon, nitrogen oxides, sulfur oxides, volatile organic compounds, polycyclic aromatic hydrocarbons, and fine particulate matter.

Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog.

Important Uses of Air

• Sustain life and growth.
• Combustion.
• Maintaining Temperature.
• Supplier of Energy.
• Photosynthesis.

Air is important for living things. Breathing is part of a process called respiration. During respiration, a living thing takes in oxygen from the air and gives out carbon dioxide. This process gives animals and plants the energy to eat, grow, and live life!

The air gives energy for the function of living things. Plants get their food from the event of Photosynthesis. Photosynthesis happens with the help of oxygen. Nitrogen is very useful for the growth of plants as well as trees.

Components of Air – Nitrogen, Oxygen, Carbon Dioxide, Water Vapor and Other Gases.

Solution: The main components of air are: Nitrogen. Oxygen….Composition of air is:

• Nitrogen – 78%
• Oxygen – 21%
• Carbon dioxide – 0.03 %
• Inert gases – 0.9%

oxygen

Pure air consists of a mixture of gases in proper proportion which is good for living beings. That is, by volume about 78% of nitrogen, about 21% of oxygen and in very small quantities of carbon dioxide, argon, methane, ozone and water vapour.

Pure air contains nitrogen, oxygen and small amounts of other gases.

Explain the differences between pure air and polluted air. Pure air is free from germs and harmful gases. It contains 78% nitrogen, 21% oxygen and small amount of other gases and dust particles. Polluted air contains harmful gases and unwanted substances.
