Air Pollution Questions: Importance, Causes, Effects, Impact

Q1. How do you define air pollution?

Ans: Air pollution is the contamination of the atmosphere by substances that are harmful to human health or the health of other living things, or that harm the environment's resources or climate.

Q2. Why is it important to solve air pollution?

Ans:There is air pollution everywhere. The majority of people in the globe reside in regions with high air pollution levels. It compromises the health and wellness of people, lowers standard of living, and may have detrimental effects on the economy and ecosystems. The most vulnerable individuals and communities are also disproportionately affected by these effects.The greatest environmental threat to human health on the planet is air pollution.

Q3. What are the causes of air pollution?

Ans:There are many different sources of air pollution, both natural and generated by human activity.Volcanic eruptions, sea spray, soil dust, naturally occurring forest fires, and lightning are examples of natural sources.Power production, transportation, industry, home heating and cooking, agriculture, solvent usage, oil and gas production, rubbish burning, and building are a few of the most frequent sources associated with human activity.

Q4. How long has air pollution been an issue?

Ans:Since Hippocrates, in 400 BC, air pollution has been understood as a hazard to human health. From the eighteenth century onward, measurements show the expanding scope of poor air quality in urban centers and close to industry, as well as the chemical characteristics of the gases and particulate matter. The following two millennia witnessed numerous written accounts of air pollution in various countries.

Q5. In what ways can air pollution harm people's health?

Ans:The strongest evidence points to fine particulate matter as the air pollutant that poses the greatest threat to human health. PM 2.5, as it is also known, has a diameter of 2.5 micrometers or smaller. The size of these tiny particles is 40 times smaller than the diameter of a human hair, making them undetectable to the human eye. They are capable of seriously harming our bodies. These particles are tiny enough to enter our lungs deeply, where they can inflame delicate lung tissue.

Q6. What health effects does air pollution have on kids?

Ans: Due to their specific vulnerability and exposure, children are more susceptible to the harmful health impacts of air pollution. The lungs and brains of children are still developing, and their blood arteries are smaller. Children are more affected by polluted air than adults because they have lower immune systems.

Q7. What degree of air pollution is considered safe for your health?

Ans: There is no evidence that there is a level of air pollution that is completely safe, especially when it comes to particulate matter and NO2. While everyone experiences different levels of health impacts from air pollution, across large city or rural populations, there is no proof that there is a level of air pollution that is completely safe. Adherence to such values would prevent negative effects on public health. Updated air quality recommendations for typical air pollutants, as well as interim goal values for PM (PM 2.5 and PM 10), O3, NO2,and SO 2 were issued by the WHO in 2021.

Q8. What impact does air pollution have on biodiversity, food, agriculture, and forests?

Ans:By far the most significant air contaminant impacting plant development is ozone (O 3). Crop productivity, forest health, and biodiversity all suffer as a result. Different plant species have varying levels of sensitivity to O3. Those with lower levels will have less of an ecological benefit over more resistant ones. Some crops, particularly beans, are extremely susceptible to ozone.

Q9. What makes acid rain a part of air pollution?

Ans:Some air pollutants cause ‘acid rain’, a problem that received particular focus in Europe and North America in the 1980s and 90s. Sulfur dioxide (SO 2 ) and nitrogen oxides (NOx) react with water in the atmosphere, producing sulphuric acid and nitric acid that return to earth as ‘acid rain’.

Q10. What part does air quality monitoring play in managing air quality?

Ans:When addressing air quality, nations confront a number of difficulties. Many local governments and national governments may find it difficult to afford the expense of certified monitoring equipment, as well as routine calibration and maintenance. It is crucial to remember that the expense of air quality monitoring is far cheaper than the expense of reducing air pollution, the former being a public expenditure and the latter a private one. Therefore, in order to provide accurate data on air quality

Q11. What actions can the government take to improve air quality?

Ans: Governments must provide residents with access to clean air. There are several options available to all levels of government for improving air quality. The problem of air pollution has remedies. Air pollution has an impact on everyone, and there are several reasons and remedies for it. There isn't a universally applicable set of policy recommendations for improving air quality that would apply to all cities, countries, and regions; such a strategy would be neither practical nor desirable for a problem that has an impact.

Q12. What can we do to improve air quality in my community?

Ans: Using clean forms of transportation when they are available is one of the things people may do to lessen their own impact on air pollution. By acquiring a hybrid, electric, or automobile with a smaller engine, you may lower your emissions. Along with the cutting-edge car emissions management technology mentioned above, we may employ clean fuels. If you drive a car, make sure it receives routine maintenance to reduce its impact on air pollution. For heating, lighting, and cooking, we may employ eco-friendly materials and methods.

Q13. What are the main environmental effects of air pollution?

Ans:Eutrophication,smog,ozone loss,acid deposition,ozone loss,etc are some of the main environmental effects of air pollution.

Q14. What are the main air contaminants?

Ans:Sulphur dioxide,nitrogen oxides,VOC (Volatile Organic Compounds),Ammonia (NH3), Carbon monoxide (CO),ozone,etc are some of the main air contaminants.

Q15. Which is the most air polluted country?

Ans:According to reports Bangladesh is the most polluted country in the whole world followed by Pakistan.

Q16. What is eutrophication?

Ans:Increased levels of plant nutrients in water result in eutrophication. Ecology is disturbed by eutrophication as the water organisms get less oxygen.

Q17.What are the categories of air pollution?

Ans:The types of air pollution include biological air pollution, which includes pollen, tiny insects, and microorganisms (bacteria, fungi, yeasts and algae). physical air pollution, including radioactive radiation, thermal pollution, sound, and odor. Chemical pollutants in the air, include ozone, aerosols, and ammonia.

Q18. What are the natural sources of air pollution?

Ans:Natural sources of air pollution are dust storms, volcanic eruptions and emissions from plants.

Q19. How does air pollution spread?

Ans:The dispersion of air pollution happens mainly due to wind and weather. The particle size of the compounds and the height at which the pollution was released into the atmosphere are the key factors that determine how far air pollutants are carried. High smoke intensity emissions of fumes into the air will mix with the air, resulting in relatively low local concentrations.

Q20. What are the various processes that air pollution undergoes?

Ans: A variety of processes that are involved in air pollution are emission,travel,transact,dispersion,impairment and deposit.

Q21. What is greenhouse gas emission?

Ans:Greenhouse gas emissions make the greenhouse effect stronger, which causes climate change.Over years, emissions generated by humans have increased atmospheric carbon dioxide by around 50%.

Q22. What are the long term effects of air pollution?

Ans:Long term exposure to air pollution has lead to lungs that are ageing more quickly.

impaired lung function and a loss of lung capacity,the emergence of conditions including asthma, bronchitis, emphysema, and maybe cancer and reduced lifespan.

Q24. What is the major cause of air pollution in india?

Ans: According to the Government of India, the major contributor of Air Pollution in India is dust and construction.
