The correct answer is i, ii, iii, iv, and v only.

Key Points

  • Ambient air quality refers to the condition or quality of air surrounding us in the outdoors.
  • National Ambient Air Quality Standards are the standards for ambient air quality set by the Central Pollution Control Board (CPCB).
  • The CPCB has been conferred this power by the Air (Prevention and Control of Pollution) Act, 1981.
  • National Ambient Air Quality Standards have been established for air pollutants: lead, carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide, ammonia, and PM (PM10, and PM2.5).
  • The worst reading in these pollutants represents the AQI for that city.
  • The Central Pollution Control Board (CPCB), a statutory organization, was constituted in September 1974 under the Water (Prevention and Control of Pollution) Act, 1974.
  • It serves as a field formation and also provides technical services to the Ministry of Environment and Forests of the provisions of the Environment (Protection) Act, 1986.
  • The National Air Monitoring Programme (NAMP) has been established with objectives to determine the present air quality status and trends and to control and regulate pollution from industries and other source to meet the air quality standards.

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. Select the most suitable from the following options A-statement is absolutely true B-statement is probably true C-statement can not be reviewed D-statement is completely false
