How does photochemical smog form?

Answer 1

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.

Answer 2

Photochemical smog forms when pollutants from car emissions and industrial processes react with sunlight in the atmosphere. These reactions produce harmful substances like ozone and nitrogen dioxide, which can create a hazy layer of smog over populated areas.

Answer 3

Smog is a kind of air pollution; the word "smog" is a portmanteau of smoke and fog. Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide. Modern smog does not usually come from coal but from vehicular and industrial emissions that are acted on in the atmosphere by sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog.

Answer 4

photo as a prefix means light. Photochemical smog is when sun light reacts with Nitrogen oxides and other organic compounds, forming dangerous levels of 03 at ground level.
