What is produced during photochemical smog?

What is produced during photochemical smog?

Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.

What are the 3 major ingredients of photochemical smog?

The main components of photochemical smog are nitrogen oxides, Volatile Organic Compounds (VOCs), tropospheric ozone, and PAN (peroxyacytyl nitrate). All of these substances are very chemically reactive and are irritating to humans and other living things.

What are some effects of photochemical smog?

Ozone and nitric oxide (NO) can irritate the nose and throat and their high concentration causes a headache, chest pain, dryness of the throat, cough and difficulty in breathing. Photochemical smog leads to cracking of rubber and extensive damage to plant life.

What is photochemical smog give Example Class 11?

Photochemical smog refers to a type of smog which is formed when the ultraviolet light from the sun reacts with nitrogen oxides present in the atmosphere. This smog can cause a lot of adverse effects on humans and other living organisms.

Is CFC a component of photochemical smog?

Some of the common nitrogenous compounds are NOX, PAN of which PAN is peroxyacetyl nitrate which is a component of the photochemical smog. But the CFC or chlorofluorocarbon is not a component of the smog as it takes part in the depletion of the ozone layer.

Which product of incomplete combustion gives photochemical smog its yellow Colour?

Ground-level ozone is one of the major components of photochemical smog and a key health risk linked to breathing problems, asthma, reduced lung function and respiratory diseases.

What is photochemical smog Class 10?

What is photochemical smog in environmental chemistry?

Photochemical smog is a type of air pollution due to the reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NOx) and volatile organic compounds (hydrocarbons). Smog is a byproduct of modern industrialization. Oxidation: Photochemical smog is also referred to as oxidizing smog.

Is ethanol a component of photochemical smog?

It is not a component of photochemical smog. while other given compounds are the main components of photochemical smog. Among the given chlorofluorocarbons are the compounds that are responsible for ozone depletion which degrades ozone into molecular oxygen.

Is unsaturated hydrocarbon a component of photochemical smog?

\[N{O_2}\] and unsaturated hydrocarbons are the primary constituents of photochemical smog. These primary constituents are introduced into the atmosphere via vehicular emissions and industrial processes.

Is SO2 a component of photochemical smog?

Since SO2 is a reducing agent and photochemical smog is normally con- sidered to be an oxidizing system, an interaction would be expected. Atten- tion naturally is directed toward the reaction of SO2 with ozone, the major oxidant in photochemical smog.

What is a major component of photochemical smog?

The main components of photochemical smog are nitrogen oxides, Volatile Organic Compounds (VOCs), tropospheric ozone , and PAN (peroxyacytyl nitrate). All of these substances are very chemically reactive and are irritating to humans and other living things.

What kinds of harm does photochemical smog cause?

Photochemical smog is a unique type of air pollution which is caused by reactions between sunlight and pollutants like hydrocarbons and nitrogen dioxide. Although photochemical smog is often invisible, it can be extremely harmful, leading to irritations of the respiratory tract and eyes.

What is the major source of photochemical smog?

Precursors of Photochemical Smog. Ozone, the most common chemical in urban smog, is the result of a complex photochemical reaction between nitrogen oxides and hydrocarbons . The main source of nitrogen oxide pollution is motor vehicle exhaust, according to the Environmental Protection Agency.

What are problems caused by photochemical smog?

Why is Photochemical Smog Bad: Its Harmful Effects On Human Health: It causes irreversible damage to the lungs and heart, causing emphysema, bronchitis, and asthma in persons with allergies. On Environment: It has devastating effects on the environment that affects growth in both plants and animals. Other Effects: It corrodes metals, stones, and painted surfaces.
