Ground-level ozone (a key component of smog) is associated with many health problems, such as diminished lung function, increased hospital admissions and emergency room visits for asthma, and increases in premature deaths.
What are the harmful effects of smog?
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 four effects of smog?
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 is smog and its effects?
Smog is composed of a mixture of air pollutants that can endanger human health. Various human health problems such as emphysema, asthma, chronic bronchitis, lung infections, and cancers are caused or exacerbated by the effects of smog.
What are 4 negative effects of pollution?
In addition, long-term exposure to air pollution can cause cancer and damage to the immune, neurological, reproductive, and respiratory systems. In extreme cases, it can even cause death.
What are the effects of smog on human and ecosystem 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 5 effects of poor air quality?
Both short- and long-term exposure to air pollution can lead to a wide range of diseases, including stroke, chronic obstructive pulmonary disease, trachea, bronchus and lung cancers, aggravated asthma and lower respiratory infections.
What are 3 effects of poor air quality?
Poor air quality can irritate the eyes, nose, and throat, cause shortness of breath, aggravate asthma and other respiratory conditions, and affect the heart and cardiovascular system.
What are the 5 effects of pollution?
Effects of Air Pollution
- Harming Human Health.
- Harming Animals and Plants.
- Causing Acid Rain.
- Reducing Sunlight.
- Making a Hole in the Ozone Layer.
- Adding Too Much Nitrogen to the Land.
- Effects of Greenhouse Gas Pollution.
What is the main cause of smog?
It forms when volatile organic compounds, or VOCs, and nitrogen oxides participate in chemical reactions in the presence of sunlight. VOCs: Carbon-containing compounds that easily evaporate at room temperature and enter the surrounding air. Many VOCs are emitted naturally by plants.
What is negative and positive pollution?
Negative soil pollution is reduction in soil productivity due to erosion and over use. Positive soil pollution is reduction in soil productivity due to addition of undesirable substances e.g., agrochemicals, industrial wastes, air pollutants washed down by rain, faulty sanitation etc.
What are the top 10 things that cause pollution?

What are the top 5 causes of pollution?
Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide.
What are the effects of smog on plants?
The effects of pollution on plants include mottled foliage, “burning” at leaf tips or margins, twig dieback, stunted growth, premature leaf drop, delayed ma- turity, abortion or early drop of blossoms, and reduced yield or quality (Figure 1).
How does smog affect global warming?
Some Air Pollutants Cause the Climate to Warm
The recent increase in greenhouse gas pollution is trapping excess heat and causing the climate to warm. Air pollution includes greenhouse gases such as carbon dioxide. Greenhouse gases cause the climate to warm by trapping heat from the Sun in the Earth’s atmosphere.
What are the harmful effects of smog Class 9?
Smog effects are harmful to the senior citizens, children with heart and lung problems. Due to photochemical smog, pneumonia, inflammation of tissues, fatigue and premature of lungs and death. There are so many harmful effects of photochemical smog on human beings which causes diseases of lungs and heart.
What type of pollution is smog?
Smog is air pollution that reduces visibility. The term “smog” was first used in the early 1900s to describe a mix of smoke and fog. The smoke usually came from burning coal. Smog was common in industrial areas, and remains a familiar sight in cities today.
What are the 4 causes of poor air quality?
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 4 forms of long term effects of poor air quality?
The long-term effects associated with air pollution are chronic asthma, pulmonary insufficiency, cardiovascular diseases, and cardiovascular mortality.
Which of the following diseases are caused by smog?
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.
How does air pollution affect plants and animals?
Air pollutants can poison wildlife through the disruption of endocrine function, organ injury, increased vulnerability to stresses and diseases, lower reproductive success, and possible death.
