  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect bu statements 2 is correct.

  4. Both statements 1 and 2 are incorrect.

Show answer
Correct Option: A
Explanation:

50% of Carbon monoxide emissions are from automobiles. Normally CO has a brief residence in atmosphere and gets oxidized to co2. However, in congested and closed areas if proves quite harmful. Carbon monoxide combines with haemoglobin, produces carboxyhaemoglobin or COHb. At 50 ppm, CO converts 7.5% of haemoglobin into carboxyhemoglobin within 8 hours. It impairs oxygen transport resulting in giddiness, headache, decreased vision, cardiovascular malfunction, and asphyxia.

So, the correct answer is 'Both statements 1 and 2 are correct'

Among the following which one causes more indoor chemical pollution?

evs - i life is precious road safety and pollution pollution of natural resources air pollution and its effects

  1. Burning coal

  2. Burning cooking gas

  3. Burning mosquito coil

  4. Room spray

Show answer
Correct Option: A
Explanation:
Among the given four options, both burning of coal and burning of mosquito coil will cause chemical pollution, but burning of coal will cause more pollution. The main ingredient in mosquito coils is pyrethrum C (a natural extract from the Chrysanthemum flower). At high doses, it is responsible for various respiratory disorders. The coal leads to release of a wide array of air pollutants $ \left( { CO } _{ x }{ SO } _{ x }{ NO } _{ x }\quad etc. \right) . $ Among these, CO is very dangerous, it interfer with breathing process. People are generally advised not to sleep with coal burning in the closed room.
So, the correct answer is 'Burning coal'.

All of the following is the method to control air pollution except

  1. Use of CNG gas

  2. Use of LPG gas

  3. Aforestation

  4. Use of cycle

Show answer
Correct Option: B
Explanation:

The domestic cooking gas cylinder contains Liquid petroleum gas.
  • Its composition is propane or butane or a mixture of both, are flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles.
  • Use of LPG is not a method to control air pollution because Inhaling of LPG vapour can cause irritation in nose and throat, headache and nausea, vomiting, dizziness and loss of consciousness.
  • Hence Use of LPG gas is not a method to control air pollution.
  • So, the correct answer is 'Use of LPG gas'.

Asthma can be caused by

  1. Water pollution

  2. Soil erosion

  3. Air pollution

  4. Thermal pollution

Show answer
Correct Option: C
Explanation:
  • Asthma is a condition in which a person's airways become inflamed, narrow and swell and produce extra mucus, which makes it difficult to breathe.
  • The symptoms of asthma often present in periodic attacks or episodes of tightness in the chest, wheezing, breathlessness, and coughing.
  • Asthma is caused by many reasons such as air pollution, smoking, dust, pets, chemicals, and genetic reasons. Allergins present in the polluted air causes an inflammatory reaction is airways which leads to asthma.
  • Hence Asthma can be caused by air pollution.
  • So, the correct answer is 'Air pollution'.

In metropolitan cities, the automobiles cause air pollution.

  1. $80\%$

  2. $60\%$

  3. $50\%$

  4. $100\%$

Show answer
Correct Option: A
Explanation:

Most of the automobiles have an environmental impact up to 80 to 90 percent., It is due to fuel consumption and emissions of air pollution and greenhouse gases that are said to drive global warming.

So, the correct option is '80%'.

For corrosion of metals, there should be

business organisation and correspondence life is precious road safety and pollution pollution of natural resources air pollution and its effects

  1. Exposed surface of metal

  2. Moisture

  3. Air

  4. All the above

Show answer
Correct Option: D
Explanation:
Corrosion is a natural process of formation of oxides of metal on reaction with oxygen and moisture present in the air. Generally, all metals can corrode. A layer of rust forms on the surface of metals such as in case of iron which corrodes very fast on exposure to air. Hence, for corrosion of metals, the surface of metal should be exposed to air and there should be moisture in the air.
Hence, all the given options are correct.
So, the correct answer is 'All the above'.

Which of the following measures can be taken by people to reduce air pollution?

  1. Encourage your family to use the bus, train or bike when commuting

  2. Rapidly accelerate the transition away from coal towards clean energy sources, like solar and wind

  3. If you are buying a car, look for a fuel-efficient model

  4. All of the above

Show answer
Correct Option: D
Explanation:

People also should take initiative to reduce air pollution like 

  1. People should use public transport like bus or train for a long rout and use a bicycle for short distance.
  2. Use a renewable source of energy like solar and wind for electricity, cooking and water heating.
  3. Use fuel efficient car model for less consumption of fuel.
So the correct answer is 'All of the above'. 

Which of the following pollutants are released by burning fossil fuels and reduces visibility, especially in cold weather, when water also condenses out of the air?

business organisation and correspondence life is precious road safety and pollution pollution of natural resources air pollution and its effects

  1. Oxides of Sulphur

  2. Oxides of Nitrogen

  3. Unburnt carbon particles

  4. All of the above

Show answer
Correct Option: C
Explanation:

On burning, fossil fuel with minimum oxygen supply is given unburn carbon particle which doesn't settle down and get mix with water vapour. In winter it gets worse, visibility of air get dropdown and very hard to breath because of a minute particle present in the air. Sulphur and Nitrogen are also harmful but they are not involved in visibility problem.

so the correct option is 'Unburnt carbon particles'.

.......... is a main man-made factor to create environmental problems.
business organisation and correspondence life is precious road safety and pollution pollution of natural resources air pollution and its effects

  1. Pollution and degradation of air

  2. Climate change

  3. Over population

  4. All of the above

Show answer
Correct Option: D
Explanation:

There are various man-made factors that create the environmental problems. These factors include air pollution, degradation of air, water contamination, over population, industrial mining, climate change, deforestation, fossil fuels, fertilizer use, etc. The natural factors responsible for environmental problems include forest fire, water vapour, frost soil, etc.

Thus, the correct answer is 'All of the above.'
