Photochemical smog results from the interaction of the ultraviolet portion of sunlight and ozonee, nitrogen oxides and reactive hydrocarbons. The NOX can result from emissions from combustion sources such as car engines, the reactive hydrocarbons are also attributable to car exhaust. The ozone can come from the sunlights action on atmospheric oxygen, stratospheric ozone downwasing or chemical reactions in the atmosphere wirth NOx. The outcome is an excess of ozone, and polyaromatic hydrocarbons of several types.

Photochemical smog is caused by the action on chemicals of what?

Photochemical smog is caused by the action of sunlight on pollutants like nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the atmosphere. These pollutants react with sunlight to form ground-level ozone and other harmful compounds, creating the thick haze characteristic of photochemical smog.


How is photochemical smog formed and what harm can it cause?

Photochemical smog is formed when sunlight reacts with pollutants like nitrogen oxides and volatile organic compounds from vehicle emissions. This reaction forms ground-level ozone and other harmful pollutants. Photochemical smog can cause respiratory issues, eye irritation, and damage to vegetation.


Is photochemical smog most likely to occur when it's raining?

No, photochemical smog forms on clear, sunny days when sunlight reacts with pollutants like nitrogen oxides and volatile organic compounds in the air. Rain can help reduce smog levels by washing away pollutants.


What is the thick brown haze formed when certain gases react in sunlight?

The thick brown haze formed when certain gases react in sunlight is called smog. It is typically a mixture of pollutants such as nitrogen oxides, volatile organic compounds, and particulate matter that undergo chemical reactions in the presence of sunlight to form photochemical smog.


Photochemical smog tends to form over?

urban areas with high levels of air pollution, where sunlight interacts with pollutants like nitrogen oxides and volatile organic compounds. This interaction leads to the formation of ground-level ozone and other harmful compounds, creating the characteristic haze of photochemical smog.

Photochemical smog is a brown type of smog made when?

Photochemical smog is a type of smog made when hydrocarbons and nitrogen oxides mix with sunlight.


How is photochemical smog created?

There are two major types of smog: photochemical and industrial smog. Photochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form particulate matter and tropospheric ozone. The air pollutants that are most responsible for this type of smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs). Photochemical is especially a problem in areas with many cars, coal-burning power plants, and the right weather conditions. Los Angeles, CA is a city that often has to deal with photochemical smog.

What 3 ingredients must be present for photochemical smog to form?

Photochemical smog requires sunlight, primary pollutants (such as nitrogen oxides and volatile organic compounds), and stagnant atmospheric conditions. Sunlight initiates photochemical reactions between the pollutants, leading to the formation of secondary pollutants like ozone. The stagnant air allows these pollutants to accumulate, exacerbating smog formation. Together, these ingredients create the conditions conducive to photochemical smog.
