Mar 3, 2019 · The Formation of Smog. Photochemical smog (or just smog for short) is a term used to describe air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere. One of the primary components of photochemical smog is ozone.
Jul 13, 2024 · Smog, community-wide polluted air. Although the term is derived from the words smoke and fog, it is often used to describe the pall of automotive or industrial origin that lies over many cities, and its composition is variable.
This article lucidly explains all the important information about smog; ranging from how it is created, harmful effects, different types, and measures that can be adapted to control Smog.
Feb 2, 2023 · Photochemical smog, also known as ‘summer smog,’ is formed when ultraviolet (UV) light from the sun reacts with nitrogen oxides (NOx) and volatile organic compounds (VOCs).
Smog formation in general relies on both primary and secondary pollutants. Primary pollutants are emitted directly from a source, such as emissions of sulfur dioxide from coal combustion.
Smog is mainly made of ground-level ozone and particulate matter. Here, Caltech scientists explain the smog formation process.
Oct 19, 2023 · Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents.

Feb 13, 2023 · Smog encompasses a broad category of air pollutants created through a multitude of processes that relate specifically to the atmospheric conditions of the formation region.
Aug 24, 2021 · Smog is produced by a set of complex photochemical reactions involving volatile organic compounds (VOCs), nitrogen oxides and sunlight, which form ground-level ozone.
