• Particulate matter (PM10 and PM2.
• Ozone (O3)
• Nitrogen dioxide (NO2)
• Carbon monoxide (CO)
• Sulphur dioxide (SO2)

What are major air pollutants their causes and effects on human body?

Air pollution is also considered as the major environmental risk factor for some respiratory diseases such as asthma and lung cancer. [70,71] Air pollutants, especially PMs and other respirable chemicals such as dust, O3, and benzene cause serious damage to the respiratory tract.

What is air pollution give its causes and effects?

“Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says.

What is the main cause of pollution?

The Short Answer: Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires.

What are the causes and effects of pollution?

Indoor areas can become polluted by emissions from smoking and cooking. Some of these chemicals, when released into the air, contribute to smog and acid rain. Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions.

Where is water pollution most common?

The Most Common Types of Water Contamination Around the world, agriculture is the leading cause of water degradation. In the United States, agricultural pollution is the top source of contamination in rivers and streams, the second-biggest source in wetlands, and the third main source in lakes.

What is water pollution and its effects?

Water pollution drastically affects aquatic life. Humans are affected by pollution and can contract diseases such as hepatitis through faecal matter in water sources. Poor drinking water treatment and unfit water can always cause an outbreak of infectious diseases such as cholera, etc.

What are effects of pollution?

High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications.

What are the advantages and disadvantages of air pollution?

However, there may be some small advantages to air pollution:

• Air pollution helps plants grow. Guess what our factories and cars put in the air?
• Air pollution slows climate change. Some pollutants we put out heat up the Earth, like carbon dioxide.
• Air pollution keeps polluted cities cooler in the summer.

What is the important of water pollution?

Water covers over 70% of the Earth’s surface and is a very important resource for people and the environment. Water pollution affects drinking water, rivers, lakes and oceans all over the world. This consequently harms human health and the natural environment.

Who is affected by water pollution?

The main problem caused by water pollution is the effect it has on aquatic life. Dead fish, birds, dolphins, and many other animals often wind up on beaches, killed by pollutants in their habitat. Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals.

How is water pollution caused state its effects?

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil and therefore …

How do humans affect water pollution?

Agriculture is also the main source of pollution in rivers and streams in the U.S. One way that agriculture causes water pollution is through rainwater. When it rains, pollutants, such as fertilizers, animal waste, and pesticides get washed from farms into waterways, contaminating the water.

What are the long term effects of water pollution?

If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.

What are the negative effects of water pollution?

EFFECTS OF WATER POLLUTION

• Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —.
• Contamination of the food chain.
• Lack of potable water.
• Disease.
• Infant mortality.

What will happen if we don’t fix water pollution?

If a fish or mammal eats a piece of trash, then it could die. Altered water temperatures caused by people can kill all aquatic life in a pond or a lake. Some health problems water pollution can cause include problems with people’s hearts, liver and kidneys. Also, it can cause diarrhea, cancer, and even cholera.

What will happen if we don’t fix pollution?

If air pollution is not controlled, by 2030 the air will become so poisonous that it will be necessary to use an oxygen kit to breathe easily. Rising air pollution will also lead to premature aging. Human exposure to air toxins will increase to a great extent if air pollution is not controlled.
