Viktor Fiker Dreamstime Pollution is the process of making land, water, air or other parts of the environment dirty and not safe or suitable to use.

Environmental science air pollution

Air pollution is when unwanted chemicals, gasses, and particles enter the air and the atmosphere causing harm to animals and damaging the natural cycles of the Earth. Natural Causes of Air Pollution Some sources of air pollution come from nature.

These include eruptions of volcanoes, dust storms, and forest fires. Human Causes of Air Pollution Human activity is a major cause of air pollution, especially in large cities. Human air pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane Environmental science air pollution from landfills.

Burning Fossil Fuels One of the ways that humans cause the most air pollution is by burning fossil fuels. Fossil fuels include coal, oil, and natural gas. When we burn fossil fuels this releases all sorts of gasses into the air causing air pollution such as smog.

Effects on the Environment Air pollution and the release of gasses into the atmosphere can have many negative effects on the environment. Global warming - One type of air pollution is the addition of carbon dioxide gas into the air. Some scientists believe that releasing too much carbon dioxide into the atmosphere is one of the causes of global warming.

This upsets the balance of the carbon cycle. The ozone layer - The ozone layer helps protect us from harmful rays from the sun. It is getting damaged from air pollution such as methane gas from livestock and CFCs from spray cans.

Acid Rain - Acid rain is created when gasses such as sulfur dioxide get high into the atmosphere. The wind can blow these gasses for miles and then they get washed out of the air when it rains. This rain is called acid rain and can damage forests and kill fish.

Smog in the city makes it hard to breathe and see Effects on Health Air pollution can also make people sick. It can make it difficult to breathe and cause diseases such as lung cancer, respiratory infectionsand heart disease.

According to the World Health Organization, 2. Air pollution can be especially dangerous to children living in big cities with bad smog.

Air Quality Index The Air Quality Index is a way for the government to alert people to the quality of the air and how bad the air pollution is in an area or city.

They use colors to help you determine if you should go outside. Green - the air is good. Yellow - the air is moderate Orange - the air is unhealthy for sensitive people like the elderly, children, and those with lung diseases. Red - Unhealthy Maroon - Hazardous Pollutants The actual gas or substance that causes air pollution is called a pollutant.

Here are some of the major pollutants: Sulfur dioxide - One of the more dangerous pollutants, sulfur dioxide SO2 can be generated by burning coal or oil.

It can cause acid rain as well as respiratory illnesses like asthma. Carbon dioxide - Humans and animals breathe out carbon dioxide CO2. It is also released when fossil fuels are burned. Carbon dioxide is a greenhouse gas. Carbon monoxide - This gas is very dangerous.

Environmental science air pollution

It is odorless and is produced by cars. You can die if you breathe too much of this gas. This is one reason why you should never leave your car running in the garage.

Chlorofluorocarbons - These chemicals are also called CFCs. They were used in many devices from refrigerators to spray cans. They are not used as much today, but caused significant damage to ozone layer during the time they were heavily used.Welcome. The Environmental Science and Engineering (ESE) program reaches across traditional disciplinary boundaries in its aim to provide a comprehensive understanding of our complex environment and offer efficient and effective engineering solutions to environmental problems.

Great progress has been made in achieving national air quality standards, which EPA originally established in and updates periodically based on the latest science. One sign of this progress is that visible air pollution is less frequent and widespread than it was in the s.

However, air. Pollution is the process of making land, water, air or other parts of the environment dirty and not safe or suitable to use.

This can be done through the introduction of a contaminant into a. When methods of measuring air quality are inadequate, people and the economy suffer.

We know that air pollution is bad for our health, especially in congested areas like cities. Environmental Science Scout's Name: _____ Environmental Science - Merit Badge Workbook Page. 5 of 18 b. Air Pollution 1. Perform an experiment to test for particulates that contribute to air pollution.
