Detailed Solution for Test: Air Pollution (NCERT) - Question 2

Electrostatic precipitators (ESPs) are very efficient devices which remove 99 % of particulates present in the industrial and thermal plant exhausts. There are electrode wires and a stage of collecting plates. The collecting plates. The collecting plates wires and a stage of collecting plates. The collecting plates are connected with ground. The electrode wires are provided with several thousand volts electric current. It creates a corona which releases electrons. The electrons attach to the suspended particles and make them negatively charged within a fraction of a second. Air with charged particles passes slowly over collecting plates. The particulate matter settles over them and are removed.

Detailed Solution for Test: Air Pollution (NCERT) - Question 6

The Air (Prevention and Control of Pollution ) Act 1981 deals with the preservation of air quality and the control of air pollution with a concern for the detrimental effects of air. By an amendment in 1987m noise was also recognised as an air pollutant.

Test: Air Pollution (NCERT) - Question 7

Which one of the following statements is incorrect regarding Bhopal gas tragedy?

Detailed Solution for Test: Air Pollution (NCERT) - Question 7

Bhopal gas tragedy, the world's worst industrial catastrophe was not due to radioactive fallout, but it was because of leakage of phosgene and methyl isocyanate gas.

Test: Air Pollution (NCERT) - Question 8

Which of the following is the way to control vehicular air-pollution in Indian cities?

Detailed Solution for Test: Air Pollution (NCERT) - Question 8

CNG produces 45% fewer hydrocarbons than gasoline.
Unleaded petrol doesn't produce lead in the atmosphere.
Catalytic converter reduces emissions of three harmful compounds found in car exhaust which are Carbon monoxide (a poisonous gas) Nitrogen oxides (a cause of smog and acid rain) Hydrocarbons (a cause of smog)

Test: Air Pollution (NCERT) - Question 9

Read the given statements and select the correct option.
Statement 1: Traffic jams are likely to cause giddiness, exhaustion, reduced vision, etc.
Statement 2: Carbon monoxide from vehicles causes these problems by reducing Ocarrying capacity of haemoglobin.

Detailed Solution for Test: Air Pollution (NCERT) - Question 9

50% carbon monoxide emissions are from automobiles. Normally CO has a brief residence in atmosphere and gets oxidised to CO2. However, in congested and closed areas it proves quite harmful. Carbon monoxide combines with haemoglobin produces carboxyhaemoglobin of COHb. At 50 ppm, CO converts 7.5 % of haemoglobin into carboxyhaemoglobin with 8 hours. It impairs oxygen transport resulting in giddiness, headache, decreased vision, cardiovascular malfunction and asphxia.

Test: Air Pollution (NCERT) - Question 10

Study the following statements regarding acid rain and select the incorrect ones.
(i) Acid rain refers to the rainfall and other forms of precipitation with a pH of less than 5.
(ii) Oxides of sulphur and nitrogen are released from automobile exhausts, industries, power plants, etc.
(iii) These oxides of sulphur and nitrogen, may react with water in the air and form sulphuric acid (H2SO4) and nitric acid (HNO3)
(iv) Acid rain has harmful effects on animals and human beings but no characteristic impact on plants.

Detailed Solution for Test: Air Pollution (NCERT) - Question 10

Acid rain damages plants by direct effect on foliage and growing point- chlorosis, necrosis, defoliation, dieback. It causes leaching of essential minerals of soil.

Test: Air Pollution (NCERT) - Question 11

Chemicals responsible for the Bhopal gas tragedy were

Detailed Solution for Test: Air Pollution (NCERT) - Question 11

The Bhopal disaster or Bhopal gas tragedy was an industrial accident. It happened at a Union Carbide subsidiary pesticide plant in the city of Bhopal, India. On the night of 2-3 December 1984, the plant released approximately 40 tonnes of toxic methyl isocyanate (MIC) gas, exposing more than 500,000 people to toxic gases. The plant in Bhopal where the disaster happened started to produce 'Carbaryl' in 1977. Carbaryl is mainly used as an insecticide. The disaster happened because water entered a tank containing Methyl isocyanate. This caused a chemical reaction which resulted in the buildup of much Carbon dioxide, among other things. The resulting reaction increased the temperature inside the tank to reach over 200 °C (392 °F). The pressure was more than the tank was built to withstand. The tank had valves to control the pressure. These were triggered in an emergency, which reduced the pressure. As a result, large amounts of toxic gases were released into the environment. 

Test: Air Pollution (NCERT) - Question 12

Which of the following is the most dangerous metal pollutant of automobile exhaust?

Detailed Solution for Test: Air Pollution (NCERT) - Question 12

Automobiles burn petroleum inefficiently causing 80% of air pollution and 75% of noise pollution in urban areas. They release hydrocarbons (13.7%), carbon monoxide (77.2%), nitrogen oxides (7.7%), sulphur oxides, ammonia, aldehydes and lead (90% of total lead poisoning). Lead is present in petroleum in the form of Pb(CH3)4 and Pb(C2H5)4 as antiknock agent.

Test: Air Pollution (NCERT) - Question 13

Acid rains are produced by

Detailed Solution for Test: Air Pollution (NCERT) - Question 13

Acid rain is caused by large-scale emission of acidic gases into the atmosphere from thermal power plants, industries, and automobiles. The common ones are sulfur dioxide, nitrogen oxides NOx, volatile organic carbons VOCs and hydrogen chloride. NOx is also produced in the atmosphere through lightning. Sulfur dioxide and nitrogen oxides are changed in the atmosphere into sulphuric acid and nitric acid by combining with oxygen and water.

Test: Air Pollution (NCERT) - Question 14

Lichens are the indicators of

Detailed Solution for Test: Air Pollution (NCERT) - Question 14

Lichens are indicators of air pollution, espedav of the concentration of sulphur dioxide in the atmosphere. Air pollutants dissolved in rain water, mainly sulphur dioxide can damage lichens and prevent them born growing. So, lichens are natural indicators of air pollution.
