Questions Related to industrial pollution and degradation of environment

Introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e, physical systems or living organisms, is called as

  1. Adulteration

  2. Fortification

  3. Pollution

  4. Enrichment


Correct Option: C
Explanation:
  • Pollution is the introduction of contaminants into the natural environment that causes adverse change. 
  • Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. 
  • Hence, Introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e, physical systems or living organisms, is called Pollution.
  • So, the correct answer is 'Pollution'.

Which ecosystem generate wealth as well as causes pollution?

  1. Man subsidized solar power ecosystem

  2. Unsubsidized natural solar powered ecosystem

  3. Naturally subsidized solar powered ecosystem

  4. Fuel power ecosystem


Correct Option: D

The pollutant which effects more to the organism of higher trophic level is  

  1. biodegradable sewage

  2. heavy metal salts and non biodegradable phenolic compounds

  3. $C{O _2}$

  4. $S{O _2}$


Correct Option: B
Explanation:

Non- biodegradable compounds such as DDT and mercury accumulate in the tissues of organisms that consume them since they do not break down easily. As a result, when they, in turn, are consumed by secondary organisms their amount magnifies. This is known as biomagnification. Hence, such non-biodegradable compounds affect the organisms of higher trophic level more. So, the correct option is 'heavy metal salts and non-biodegradable phenolic compounds'.

Which is not a positive pollution -

  1. More use of bio fertilizer

  2. Land filling by wastes

  3. Deforestation

  4. Deforestation of nuclear waste in soil


Correct Option: C
Explanation:
Deforestation is a permanent destruction of forests in order to make the land available for other uses and resulting in damage to the quality of land. It leads to loss of many animal and plant species by disturbing their habitat that may result in their extinction.
So the correct answer is 'Deforestation'.

Soap and detergents are the source of organic pollutants like:

  1. Glycerol

  2. Polyphosphates

  3. Sulphonated hydrocarbons

  4. All of these


Correct Option: D

Effect of pollution is first marked on 

  1. Micro-organisms

  2. Green vegetation of an area

  3. Food crop

  4. None of the above


Correct Option: B
Explanation:

Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminium. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These influence strongly the process of photosynthesis whose rate declines sharply. Also, the leaves of the trees have an important role in the retention of the particulate matters; they are mostly affected when the wet and dry atmospheric deposition increase.

So, the correct answer is option B.

Any unfavorable alteration of the environment may be called as

  1. eutrophication

  2. environmental pollution

  3. biomagnigication

  4. bioaccumulation


Correct Option: B

During inversion, visibility is reduced and pollutant concentration is

  1. Minimized

  2. Maximized

  3. Reduced

  4. Decreased


Correct Option: B
