Consider the following pollutants A) Carbon Monoxide (CO) B) Oxides of nitrogen (NOX) C) Suspended Particulate Matter (SPM) D) Unburnt hydrocarbons Which of the pollutants given above are released from vehicular emissions? Correct Answer All of the above

The Correct answer is All of the above.
 
Important Points
  • Vehicles are mainly responsible for more than 80 per cent of total air pollution.
  • The major pollutants released from automobiles, locomotives, aircraft, etc., include Carbon Monoxide (CO), Unburnt hydrocarbons and nitrogen monoxide, nitrogen dioxide, suspended particulate matter emissions. Hence option 4 is Correct.
  • In metropolitan cities, vehicular exhausts account for most of the CO, hydrocarbons, oxides, and suspended particulate matter emissions.
Additional Information
Carbon Monoxide-
  • It is a colourless, odourless gas that is produced by the incomplete burning of carbon-based fuels including petrol, diesel, and wood.
  • It is also produced from the combustion of natural and synthetic products such as cigarettes.
  • It lowers the amount of oxygen that enters our blood.
  • It can slow our reflexes and make us confused and sleepy.
Suspended Particulate Matter-
  • It consists of solids in the air in the form of smoke, dust, and vapour that can remain suspended for extended periods and is also the main source of haze which reduces visibility.
  • The finer of these particles, when breathed in can lodge in our lungs and cause lung damage and respiratory problems.

In this question, a passage and a statement related to it have been given. Read carefully the verse and review the statement based on it. Delhi, which is one of India's capital an d one of the largest cities in the world, is undergoing severe crisis, due to its high level of urbanization, increasing population and high levels of pollution. Studies have proven that Are the biggest factors of pollution used for industrial and domestic use? And due to their use, people here emit large quantities of nitrogen oxides (NOx), ozone (O3), black carbon (BC) and microorganisms (PM). According to the 2015 Global Burden of Disease report, there were 1.09 million deaths due to PM 2.5 in India. Air pollution was included as one of the 10 biggest threats to health. According to the World Health Organization, 37 cities of India are among 100 worst polluted cities in the world, where PM10 was found to be the highest ever. For the production of ozone, together with sunlight and heat, nitrogen oxides (NOx) and organic compounds (VOCs) are needed simultaneously. Therefore, in the summer months, ozone is produced in large quantities in the cities. Statement: Air pollution is one of the top 10 factors affecting health in India.

A passage with three blanks,followed by five options, each containingone word, is given. Choose the word thatcan fill all the three blanks.
Emission ____________ are the legalrequirements governing air pollutantsreleased into the atmosphere. Emission___________ set quantitative limits onthe permissible amount of specific airpollutants that may be released fromspecific sources over specifictimeframes. They are generallydesigned to achieve air qualitystandards and to protect human life.Many emissions ____________ focus onregulating pollutants released byautomobiles (motor cars) and otherpowered vehicles. Others regulateemissions from industry, power plants,small equipment such as lawn mowersand diesel generators, and other sourcesof air pollution. While this have beenused to dictate limits for conventionalpollutants such as oxides of nitrogen andoxides of sulphur (NOx and SOx), thisregulatory technique may be used toregulate greenhouse gasses, particularlycarbon dioxide (CO2). In the US, this isgiven in pounds of carbon dioxide permegawatt-hour (lbs. CO2/MWhr), andkilograms CO2/MWhr elsewhere.
The Volkswagen emissions scandal (also called "emissionsgate" or "dieselgate") began in September 2015, when the United States Environmental Protection Agency (EPA) issued a notice of violation of the Clean Air Act to German automaker Volkswagen Group. The agency had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate their emissions controls only during laboratory emissions testing which caused the vehicles' NOx output to meet US standards during regulatory testing, but emit up to 40 times more NOx in real-world driving. Volkswagen deployed this programming software in about eleven million cars worldwide, and 500,000 in the United States, in model years 2009 through 2015. According to the EPA, Volkswagen had insisted for a year before the outbreak of the scandal that discrepancies were mere technical glitches. What can be inferred from the above paragraph?
