Photochemical fog has a variety of detrimental consequences for both the environment and people. 

Key Points

  • Photochemical smog is a brownish-grey cloud formed by the action of UV light on a polluted atmosphere including hydrocarbons and nitrogen oxides.
  • Temperature inversion traps anthropogenic air pollutants, primarily ozone, nitric acid, and organic chemicals near the ground.
  • These contaminants, as well as others, have the potential to harm humans and plants.
  • Due to some of its gaseous components, photochemical smog frequently has a disagreeable odor.

Therefore, Oxides of Nitrogen, Volatile Organic Compounds, and End are essential for the formation of photochemical smog.

Additional Information

  • NO2 molecule is known to undergo a complex series of hydrocarbon processes when exposed to ultraviolet radiation, resulting in the photochemical smog components.
  • contaminants are also emitted naturally as a result of occurrences such as volcano eruptions and forest fires.

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
