Beauty of Taj may be destroyed by

  1. Flood in Yamuna

  2. Temperature mediated spoilage of marble

  3. Air pollutants from Mathura refinery

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Mathura Refinery situated close to the Taj Mahal is a threat to the marble of the Taj Mahal because the Refinery releases the air pollutants in the form of oxides of sulphur, oxides of nitrogen and oxides of carbon. These oxides then react with water and precipiate in the form of nitric acid and sulphuric acid called acid rains. Acid rains have resulted in the corrosion of the marble, making it to appear yellow. Hence, the correct answer is 'Air Pollutants from Mathura Refinery'.

Disease aggravated by pollution is ________.

  1. Scurvy

  2. Rheumatism

  3. Haemophilia

  4. Bronchitis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Air pollution is responsible for various pulmonary or respiratory diseases like asthma, emphysema, bronchitis etc. 

A. Scurvy is the bleeding disease of gums caused by the deficiency of vitamin C.
B. Rheumatism is the inflammatory disease of the membrane of the synovial joints caused due to uric acid accumulation.
C. Haemophilia is the disease related to the absence of blood clotting caused due to the genetic mutation.
D. Bronchitis is the inflammatory disease of the bronchioles caused due to air pollution.
Hence, the correct answer is 'Bronchitis'.

After thermal inversion, pollutants pile up in.

  1. Hanging cool air

  2. Hanging warm air

  3. At the boundary of cool and warm airs

  4. Soil
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In a thermal inversion, the cold air holds up the pollutants and prevents it from rising and scattering.

So, the correct option is 'Hanging cool air'.

Heat islands are formed by

  1. Water pollution

  2. Air pollution

  3. Land pollution

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The heat island is a phenomenon where heat can no longer escape. The high temperature in urban areas as compared to rural areas can be called heat island effect. With the loss of vegetation and land surface in urban areas, heat gets trapped between buildings and dense areas which cause a warming effect. The air pollution due to greenhouse gases is responsible for this. Bigger cities have large heat island effects, the waste heat from energy use, seasonal changes, local weather also contribute to heat islands.

Hence, the correct answer is 'Air pollution'.

Sulphurous smog is

  1. Photochemical smog

  2. Oxidising smog

  3. Classical smog

  4. Los Angeles smog
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Smog is the fog containing smoke. Smog is of two types depending upon the type of pollutants; classical smog and photochemical smog.
  • Classical smog, also known as London smog or Sulphurous smog, is formed when there is high concentration of sulphur dioxide and particulate matter produced due to combustion of fuels. It occurs in cold and humid climate and has reducing nature.
  • Photochemical smog, also known as Los Angeles smog, is formed when sunlight acts on the oxides of nitrogen and hydrocarbons produced from factories or by automobiles. It occurs in warm and dry climate and has oxidising nature.
So, the correct answer is 'Classical smog'.

Smog that occurs due to low temperature and has reducing environment is

  1. Photochemical smog

  2. Los Angeles smog

  3. Nonsulphurous smog

  4. London smog

D Correct answer
Explanation
Smog is the fog containing smoke. Smog is of two types depending upon the type of pollutants; classical smog and photochemical smog.
  • Classical smog, also known as London smog or Sulphurous smog, is formed when there is high concentration of sulphur dioxide and particulate matter produced due to combustion of fuels. It occurs in cold and humid climate and has reducing nature.
  • Photochemical smog, also known as Los Angeles smog, is formed when sunlight acts on the oxides of nitrogen and hydrocarbons produced from factories or by automobiles. It occurs in warm and dry climate and has oxidising nature.
Hence, the smog that occurs due to low temperature i.e. in cold climate, and has reducing environment is classical smog or London smog.
So, the correct answer is 'London smog'.

Annual number of deaths in Delhi believed to be due to air pollution is

  1. 1000

  2. 5000

  3. 7500

  4. 15000
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Motor vehicle emissions are one of the causes of poor air quality. Other causes include wood-burning fires, fires on agricultural land, exhaust from diesel generators, dust from construction sites, burning garbage and illegal industrial activities in Delhi.
  • Air pollution exposure can trigger new cases of asthma, exacerbate (worsen) a previously-existing respiratory illness, and provoke development or progression of chronic illnesses including lung cancer, chronic obstructive pulmonary disease, and emphysema. If untreated result in death.
  • An annual number of deaths in Delhi believed to be due to air pollution is 7500.
  • So, the correct answer is '7500'.

Which of the following causes degradation of RBS?

  1. Hydrocarbons

  2. Sulphur compounds

  3. Ammonia

  4. Arsenic compounds
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Arsine is the simplest compound of arsenic. It is colourless and 2.5-times denser than air, with an odour resembling garlic. Arsine binds to haemoglobin of the red blood cells, destroying them. Arsenic disrupts ATP production. Arsenic inhibits pyruvate dehydrogenase, uncoupling oxidation phosphorylation. Arsenic poisoning also occurs through arsenic–oxygen compounds, especially arsenic trioxide, As2O3 (ATO), which is 500-times more toxic than pure arsenic. 
Hence, the correct answer is ' Arsenic compounds'.

  3. Lung cancer

  4. Tuberculosis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

There are a number of chemicals, which causes lung cancer and one of them is 3, 4- benzopyrene. Benzopyrene mutates three key positions in the p53 gene, which leads to lung cancer. Hence, the correct answer is option C.
