What is smog very short answer?

Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. Smog is a problem in a number of cities and continues to harm human health.

How do you explain smog to a child?

Smog is a combination of the words smoke and fog. It’s formed when gases and fine particulate matter react in the presence of sunlight. Smog is made up of a lot of pollutants. Most harmful to our health and to the natural environment are those that come from cars, trucks and machines that run on fuels like gasoline.

What is meant by smog?

Smog is a form of air pollution. The word “smog” is a combination of the words “smoke” and “fog.” Smog is a mixture of many pollutants, mainly ground level ozone and fine particulate matter.

What type of word is smog?

A noxious mixture of particulates and gases that is the result of urban air pollution.

How is smog harmful?

Why is it harmful? When inhaled, smog irritates our airways, increasing our risk of serious heart and lung diseases. These health risks are why many cities monitor smog levels. On a high ozone-alert day, for example, your eyes and throat may burn, and you may cough and wheeze.

Can smog kill you?

Smog doesn’t necessarily kill you right away but can lead to early death—especially in people with lung or heart problems and those with weak immune systems. It’s nearly impossible to avoid smog entirely.

What are two disadvantages of smog?

Smog is a serious problem in many cities and continues to harm human health. Ground-level ozone, sulphur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma.

How can smog be prevented?

Everyone can do their part to reduce smog by changing a few behaviors, such as:

  1. Drive less.
  2. Take care of cars.
  3. Fuel up during the cooler hours of the day—night or early morning.
  4. Avoid products that release high levels of VOCs.
  5. Avoid gas-powered yard equipment, like lawn mowers.

What type of smog is harmful?

Surface-level ozone concentrations are considered unhealthy if they exceed 70 parts per billion for eight hours or longer; such conditions are fairly common in urban areas prone to photochemical smog.

How can smog affect humans?

Smog can irritate your eyes, nose and throat. Or it can worsen existing heart and lung problems or perhaps cause lung cancer with regular long-term exposure. It also results in early death. Studies on ozone show that once it gets into your lungs, it can continue to cause damage even when you feel fine.

What can government do to reduce air pollution?

These steps include: reducing toxic emissions from industrial sources; reducing emissions from vehicles and engines through new stringent emission standards and cleaner burning gasoline; and addressing indoor air pollution though voluntary programs.

What are the solution of the air pollution?

The most basic solution for air pollution is to move away from fossil fuels, replacing them with alternative energies like solar, wind and geothermal. Producing clean energy is crucial. But equally important is to reduce our consumption of energy by adopting responsible habits and using more efficient devices.

What are the main causes of water pollution?

The Causes of Water Pollution

  • Industrial Waste. Industries and industrial sites across the world are a major contributor to water pollution.
  • Marine Dumping.
  • Sewage and Wastewater.
  • Oil Leaks and Spills.
  • Agriculture.
  • Global Warming.
  • Radioactive Waste.

What are the causes and effects of water pollution?

Waterborne pathogens, in the form of disease-causing bacteria and viruses from human and animal waste, are a major cause of illness from contaminated drinking water. Diseases spread by unsafe water include cholera, giardia, and typhoid.

Do you know any disease caused by air pollution?

The most common diseases caused by air pollution include ischemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lung cancer and acute lower respiratory infections in children. Particulate air pollution has been linked with strokes, which occur when the blood supply to the brain is cut-off.
