Questions Related to pollution and industrial pollution

Smoke or dust dispersed in air is called

business organisation and correspondence industrial pollution and degradation of environment pollution and industrial pollution pollution and its type pollutions

  1. Fog

  2. Smog

  3. Haze

  4. Mist

Show answer
Correct Option: C
Explanation:

Haze refers to the accumulation of smoke, dust, particulate matter and other dry particulates in the atmosphere. The formation of haze reduced visibility and it generally occurs in an area which is farther from the source of smoke and dust. 

A. Fog is the condensation of water droplets and mixed dust particles near the earth's surface, forming the ground clouds. This generally occurs in low atmospheric temperature.
B. Smog occurs when the smoke and dust particles condense around the water and their cumulative condensation.
C. Haze is the dispersal or smoke or dust in the air.
D. Mist is the dispersion of the water droplets in the air. It can be caused by the haze.
Hence, the correct answer is 'Haze'.

What of the following statements is correct?

  1. Benzene hexachloride is non-biodegradable pollutant.

  2. Anthropogenic air pollutants are natural in origin.

  3. Carbon monoxide is a primary air pollutant.

  4. SO$ _2$ causes brown air effect during traffic congestion in cities.

Show answer
Correct Option: B
Explanation:
Anthropogenic air pollutants are the pollutants caused or influenced by humans. Anthropogenic air pollutant (carbon dioxide) is that portion of carbon dioxide in the atmosphere that is produced directly by human activities, such as burning fossil fuels, rather than by such processes as respiration and decay.
So, the correct answer is 'Option B-Anthropogenic air pollutants are natural in origin'.

  1. Least use of fossil fuel

  2. The effluent of factories should be treated before discharge into surrounding environment

  3. By using more biodegradable products

  4. All of the above

Show answer
Correct Option: D
Explanation:
  • Environmental pollution is the release of chemical waste that causes detrimental (causing harm) effects on the environment. Environmental pollution is often divided into water pollution, air pollution, and soil pollution.
  • Environmental pollution can be controlled by Least use of fossil fuel, The effluent of factories should be treated before discharge into the surrounding environment and By using more biodegradable products.
  • So, the correct answer is 'All the above'.

Which statement is wrong about pollution?

  1. Leaded petrol is used in vehicle that has catalytic converter

  2. Hot water releases from thermal power plants

  3. Presence of DDT in food chain

  4. Biological control does not create pollution

Show answer
Correct Option: A

Spraying of DDT on crops produces pollution of 

business organisation and correspondence industrial pollution and degradation of environment pollution and industrial pollution pollution and its type pollutions

  1. Soil and water only

  2. Air and soil only

  3. Air, soil and water

  4. Air and water only

Show answer
Correct Option: C
Explanation:

Large amounts of DDT are released into the air and on soil or water, when sprayed on crops and forests to control mosquitoes and other insects. Also, DDT may enter the atmosphere when it is evaporated from contaminated water and soil. DDT in the air may then be deposited on land or surface waters. This cycle of evaporation and deposition may be repeated many times. As a result, DDT causes an undesirable change in the atmosphere.

  1. Sewage

  2. Distortion

  3. Spoilage

  4. Pollution

Show answer
Correct Option: D
Explanation:

There are many contaminants that contaminate the natural ecosystem. This leads to destruction of natural environment. This is called as pollution which disturbs the natural ecosystem.

Major pollution causing agent is

business organisation and correspondence environmental pollution and industries pollution and industrial pollution pollution and its type pollutions

  1. Man

  2. Animals

  3. Hydrocarbon gases

  4. None of the above

Show answer
Correct Option: A
Explanation:

Pollution can be natural or anthropogenic. Natural pollution is pollution caused by natural sources e.g. volcanic eruptions, the release of methane gas by paddy fields and cattle, soil erosion, volcanic eruptions etc. However, the major pollution source in modern time is anthropogenic. Anthropogenic pollution is due to human activities like the burning of fossil fuels, deforestation, mining, sewage, industrial effluents, pesticides, agricultural fertilizers etc.

So, the correct answer is option A.

In big cities, air pollution is mostly due to

business organisation and correspondence environmental pollution and industries pollution and industrial pollution pollution and its type pollutions

  1. Burning of fossil fuels

  2. Thermal power plant

  3. Sewage

  4. $H _2S$

Show answer
Correct Option: A
Explanation:

Major sources of atmospheric pollution are combustion of fossil fuels, mining and processing, chemical and cosmetic industries, welding, stone crushing, construction activity, textile industry etc. Most polluting gases are carbon monoxide, sulphur dioxides, unburnt hydrocarbons, nitrogen oxides and particulates. In big cities, the most important source of these pollutants is the combustion of fossil fuels in vehicles.
