Questions Related to industrial pollution and degradation of environment

For which of the following PM10 and PM2.5 Samplers are used?

  1. Food adulteration

  2. Adulterated Petrol

  3. Environment Pollution

  4. Noise Pollution


Correct Option: C

Which is not a pollutant from exhaust of motor vehicle?

  1. SO$ _2$

  2. CO

  3. Fly ash

  4. Hydrocarbon gas


Correct Option: C
Explanation:

Fly ash is produced due to the incomplete burning or combustion of the fossil fuels. The ash contains the carbon particles or flecks which are suspended in the air. The pollutants which are released from the exhaust of the motor vehicle are particulate matter, SO$ _2$, NO$ _x$, CO, etc. 

Thus, the correct answer is option C. 

Effect of pollution is first marked on

  1. Natural balance of the ecosystem

  2. Geological cycle

  3. Rainfall and climate

  4. Fauna of a place


Correct Option: A

Which of the following statements is true?

  1. Lichens are affected by SO$ _2$.

  2. All pollutants are not waste.

  3. Carbon monoxide is a serious pollutant.

  4. All of the above.


Correct Option: D

A very harmful fibrous component causing pollution and an inflicting disease of lungs in human beings is

  1. Asbestos

  2. Eichhornia roots

  3. ABS micelle

  4. Grease


Correct Option: A
Explanation:

Asbestos is widely used in shipbuilding, commercial product manufacturing, power plants, and construction. It causes air pollution. Asbestos fibers are easily inhaled because they are microscopic. Once inhaled, the fibers cling to the respiratory system, including the lining of the lungs and inner cavity tissue. Asbestos fibers are rigid hence they become lodged in the soft internal tissue of the respiratory system. They cannot be easily expelled or broken down by the body thus damaging the lungs. Thus the correct answer is option A.

Which human disease becomes aggravated by atmospheric pollution?

  1. Bronchitis

  2. Leucoderma

  3. Haemophilia

  4. Rheumatism


Correct Option: A
Explanation:

Bronchitis is caused due to infection and swollening of the bronchial tubes which carries air to the lungs. It is of two types i.e., acute and chronic. The acute is of mild type and caused by virus, even by bacteria and also exposure to substances that irritate the lungs, such as tobacco smoke, dust, fumes, vapors, and air pollution.

So, the correct answer is option A.

Floride pollution produces necrosis or chlorosis of

  1. Midrib

  2. Leaf margin and tip

  3. Stem

  4. Petiole but not lamina


Correct Option: B

Which of the following are bio pollutants? 

  1. Spores and pollen grains

  2. Algae

  3. Protonzoans

  4. Dairy and poultry waste


Correct Option: B
Explanation:
Excessive amounts of nitrates and phosphates from agricultural run-off cause a type of biopollution called eutrophication that stimulates an explosive growth of algae that depletes the water of oxygen. When the algae die are eaten by bacteria. Hence pond waters become hypoxic (oxygen poor) or anoxic (completely depleted of oxygen) due to algal blooms. Thus the correct answer is option B.

Pollution indicator plants

  1. Are resistant to pollution

  2. Can purify the atmosphere

  3. Are very sensitive to pollution

  4. Are very sensitive to pollutants


Correct Option: C
Explanation:

The pollution indicators are the agents which determine the presence of the pollutant. There is a change in the structure of the pollution indicators when there is pollutant present in the environment. The indicators are sensitive to pollution. The plants which are used as the pollution indicators show bleaching, stunting or death due to the presence of the pollutant.

Thus, the correct answer is option C. 

Labours working in a cement factory suffer from

  1. Cytosilicosis

  2. Bone marrow cancer

  3. Cardiac disease

  4. Asbestosis


Correct Option: A
Explanation:

The labours who are working in the cement factories suffer from respiratory disorders. Cement contains silica and the cement is present in the powdered form which readily gets into the atmosphere. The cement particles when inhaled results in cytosilicosis. This is a disease in which there is an accumulation of silica in the cells of the body. 

Thus, the correct answer is option A.
