Which component of a living cell are affected by the pollutant SO$ _2$ ?

  1. Membrane system of a cell

  2. Wall

  3. Plasmodesmata

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

Sulfur dioxide (SO2) is known to damage plant cells by affecting the membrane system, leading to increased permeability and loss of cellular integrity.

Which of the following gas causes haemorrhage if inhaled ?

  1. Carbon dioxide

  2. Hydrogen sulphide

  3. Ozone

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

Ozone is a toxic gas which causes severe effects on the body on inhalation. The gas causes irritation in the nose, throat and other parts of the respiratory system. Inhalation of about 0.1 ppm of the gas may result in effects like swelling and bleeding of the lungs. Haemorrhage of the lungs, stomach and intestine is a common effect of the ozone breathing. 

Thus, the correct answer is option C.

When combustion of coal takes place in insufficient air (oxygen) which gas is formed . Instead of carbon dioxide

  1. Sulphur dioxide

  2. Nitrous oxide

  3. Carbon monoxide

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

Fuels burn when they react with oxygen in the air. If there is plenty of air, complete combustion happens.  Coal is mostly carbon. During complete combustion, carbon is oxidized to carbon dioxide:
carbon + oxygen -- carbon dioxide
If there is insufficient air for complete combustion, incomplete combustion (also called partial combustion)  happens. Hydrogen is still oxidized to water, but carbon monoxide forms instead of carbon dioxide.

So, the correct answer is 'Carbon monoxide'.

'Heat islands' are produced due to

  1. Air pollution

  2. Water pollution

  3. Land pollution

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

A heat island is an area that is constantly warmer than surrounding areas. One of the reasons for the formation of heat island is air pollution. Other important reasons are changes in landscape due to the construction of buildings, roads, and other infrastructure which had replaced open land and vegetation. An island formation is the result of local changes in the environment brought about by urbanisation and release of polluting gases.

So, the correct answer is option A.

It is said that the Taj Mahal may be destroyed due to

  1. Flood in Yamuna river

  2. Decomposition of marble as a result of high temperature

  3. Air pollutants released from oil refinery of Mathura

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

A major threat to Taj Mahal is from Mathura oil refinery due to polluting gases like sulphur dioxide, hydrogen sulphide and nitrogen oxides.  When moisture gets accumulated in polluted environment, the oxides of sulfur, carbon and nitrogen from weak sulfuric, carbonic and nitric acids which are corrosive of stone, metals, paints and textiles.  Many priceless works of art have suffered more damage in the last 20 years due to increased sulfur-dioxide in the atmosphere.

Agricultural chemicals pollute the soil by

  1. Changing the pH of the soil

  2. Causing infertility of soil

  3. Increasing the mineral content in the soil

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Agricultural chemicals like fertilizers and pesticides can alter soil pH and accumulate toxic residues, which negatively impact soil fertility and microbial health.

Air pollution effects are usually found on

  1. Leaves

  2. Flowers

  3. Stems

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

Leaves are directly exposed to air pollutants and effects of air pollution are first seen on leaves. Deposition of particulate matter hampers gaseous exchange and deposition of soot interfere with the capture of sunlight. Sulphur dioxide causes the destruction of chlorophyll and necrosis. Nitrogen oxides cause defoliation, necrosis, dieback and death of plants. Other than this, acid rain damages plant by a direct effect on foliage and growing points by chlorosis, necrosis, defoliation and dieback.

In thermal inversion.

  1. Warm ground air gets overlapped by cool air

  2. Cool ground air gets overlapped by warm air

  3. Ground temperature becomes high in winter

  4. Ground temperature becomes low in summer
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A thermal inversion takes place when a layer of warm air settles over a layer of cooler air that lies just above the ground. The warm air holds down the cool air and prevents pollutants from rising and scattering.

So, the correct option is 'Cool ground air gets overlapped by warm air'.

A pollutant that causes irritation in eyes, throat and nose.

  1. CO
  2. $SO _2$
  3. $CH _4$

  4. Chlorofluorocarbons
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Inhalation of SO$ _2$ irritates the nose, throat, and airways to cause coughing, wheezing, shortness of breath, or a tight feeling around the chest. The effects of sulphur dioxide are felt just after 10-15 min of inhalation.

So, the correct option is 'SO$ _2$'.

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'.
