What is smog in simple words?
: a fog made heavier and darker by smoke and chemical fumes also : a photochemical haze caused by the action of solar ultraviolet radiation on atmosphere polluted with hydrocarbons and oxides of nitrogen especially from automobile exhaust.

When was the term smog first used?
1900s
What type of word is smog?
Smoke fog, or smog for short, is a type of intense air pollution. The word “smog” was coined in the early 20th century, and is a contraction (portmanteau) of the words smoke and fog to refer to smoky fog due to its opacity, and odor.
What does smog smell like?
Smog from burning coal—common in Pittsburgh and London—didn’t normally damage crops. Furthermore, as chemical instruments tycoon Arnold Beckman pointed out, smog in those places had a sulfurous smell (like a match) and appeared yellow or black.
What is smog and its types?
At least two distinct types of smog are recognized: sulfurous smog and photochemical smog. Sulfurous smog, which is also called “London smog,” results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal.
What is fog and smog?
In simple terms, what makes fog different from deadly smog is the smoke. Fog is formed when the water vapour in the air condenses and the resulting water droplets just stay in the air, engulfing the air with a whitish layer what we know as fog. This also reduces visibility. Smog is a combination of fog and smoke.
What is smog and its effects?
Smog can cause or aggravate health problems such as asthma, emphysema, chronic bronchitis and other respiratory problems as well as eye irritation and reduced resistance to colds and lung infections. 11 The ozone in smog also inhibits plant growth and can cause widespread damage to crops and forests.
Is rickets caused by smog?
Heavy smog is greatly decreases ultraviolet radiation. In fact, in the early part of the 20th century, heavy smog in some parts of Europe resulted in a decrease in the production of natural vitamin D leading to a rise in the cases of rickets. Smog causes a misty haze similar to fog, but very different in composition.
What is smog and how it is harmful for us?
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.
What are the harmful effects of smog Class 8?
The carbon particles, nitrogen oxides and sulphur dioxide of smoke combine with the condensed water vapour called fog to form smog. Smog causes cough and aggravates (makes worse) asthma and other lung diseases, especially in children.
What is smog Class 9?
Presence of suspended particles like carbon particles or hydrocarbons causes visibility to be lowered, especially in cold weather, when water also condenses out of air. This is called smog.
What is sulfurous smog?
Sulfurous smog, also known as London smog, develops due to high concentration of sulfur oxides in the air. This gas is a serious air pollutant, causing irritation to human eyes, nose and lungs. It is released into the air by sulfur-bearing fossil fuels like coal. Volcanoes also emit sulfur dioxide in the atmosphere.
Why is air polluted?
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 can you do to keep the air clean?
10 Easy Steps for Cleaner Air
- Walk, bike, carpool, or take public transit.
- Reduce heating needs by making your house more energy efficient.
- Say no to wood fire burning.
- Use hand-powered or battery-operated garden tools.
- Know before you go.
- Check your tire pressure.
- Reduce, reuse, and recycle!
- Be idle-free.
What are the 5 effects of air pollution?

- Global Warming.
- Climate Change.
- Acid Rain.
- Smog effect.
- Deterioration of fields.
- Extinction of animal species.
- Respiratory health problems.
- Deterioration in building materials.
What are the negative effects of air pollution?
Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people’s nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects.
What are the five effects of air pollution on human?
Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer’s and Parkinson’s diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight.
Can you die from air pollution?
The World Health Organization estimates that 4.6 million people die each year from causes directly attributable to air pollution. Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and respiratory allergies.
What are effects of air pollution on human health?
Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.
What are 3 ways people can cut down on air pollution?
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.
What is effect of pollution on human life?
Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease.
Why air quality is critical for human beings?
When we breathe polluted air pollutants get into our lungs; they can enter the bloodstream and be carried to our internal organs such as the brain. This can cause severe health problems such as asthma, cardiovascular diseases and even cancer and reduces the quality and number of years of life.
