Question

Difference between photochemical smog and reducing smog.

Answer 1

Hint: Smog, also known as smoke fog, is a type of severe air pollution. Smog is a contraction (portmanteau) of the words smoke and fog that refers to smoky fog due to its opacity and odor. It was coined in the early twentieth century. The term was originally intended to refer to pea soup fog, a common and serious problem in London from the nineteenth century to the mid-twentieth century.

Complete answer:
Summer smog and winter smog are two common classifications for smog. The photochemical formation of ozone is the primary cause of summer smog. Photochemical smog is the most common type of smog formed during the summer months when temperatures are higher and there is more sunlight.
The difference between photochemical smog and reducing smog is as follows:

Photochemical smog	Reducing smog
When nitrogen oxides and volatile organic compounds (VOCs) react with sunlight, photochemical smog is formed.	Smog reduction refers to episodes of air pollution marked by high levels of sulfur dioxide and smoke (or particulate aerosols).
It appears as a brown haze and is most noticeable in the morning and afternoon, particularly in densely populated, hot cities.	Because of famous incidents that occurred in that city during the 1950s, reducing smog is sometimes referred to as London-type smog.
It happens more frequently in the summer because that is when we get the most sunlight.	A temperature inversion occurs when a thin layer of the atmosphere near the earth becomes cooler than that above it, resulting in this smog.
Photochemical smog has a variety of negative consequences for both the environment and people. When the chemicals in it combine with hydrocarbons, they form molecules that irritate the eyes.	When this occurs, pollutants become trapped at ground level until the weather changes.

Note: Photochemical smog, which can be found in cities such as Los Angeles, is a type of air pollution caused by vehicle emissions and industrial fumes. These pollutants react with sunlight in the atmosphere to produce secondary pollutants, which combine with primary emissions to create photochemical smog
