What is Photochemical Smog? These 10 animal facts will amaze you. 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 Smog? Smog, of course! Smog is a type of air pollution caused by tiny particles in the air. The word comes from a mixture of the words smoke and fog and was first used to describe the hazy mixture of smoke and sulfur dioxide produced by the burning of large amounts of coal in London in the early 1900s.

Releasing Nitrogen Pollutants to the Air Nitrogen dioxide and nitric oxide molecules form during combustion in car engines, power plants, and factories. They can contribute to smog when combined with oxygen molecules and the fumes from paint and gasoline (called Volatile Organic Compounds).

Air Pollution Another pollutant associated with climate change is sulfur dioxide, a component of smog. Sulfur dioxide and closely related chemicals are known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere, which keeps sunlight out and causes Earth to cool.mog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible—that contribute to global warming.

- Figure 40.1 Chemical Transformations of Nitrogen Oxides in the Troposphere. The substances that react with nitrogen oxides to form oxidants (the final product of photochemical smog) are trace hydrocarbons (from incomplete combustion) and the hydroxyl radical.

Acid Rain Nitrogen oxides (NOx, NO2) Def: A group of gases made up of nitrogen and oxygen that cause acid rain and other environmental problems, such as smog and eutrophication of coastal waters. Burning fossil fuels, such as coal and gasoline, releases NOx into the atmosphere.

Smog Smog is a type of air pollutant. The word smog was coined in the early 20th century as a portmanteau of the words smoke and fog to refer to smoky fog.The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid 20th century.his kind of smog is caused by the burning of large amounts of coal within a city; this smog contains soot particulates from smoke, sulphur dioxide and other components.

- A step further to your question: The Difference Between Mist, Fog, Smog, Haze And Vog: There are a lot of different names for that stuff that causes reduced visibility—and an agonizingly long commute—in the morning. Mist and fog are caused by water droplets in the air, and the only difference is how far you can see. Haze is the reflection of sunlight off air pollution, while smog is what happens when pollution causes low-lying ozone.

- Smog is a type of air pollution. Smog is a mixture of smoke and fog. Smog usually forms when smoke from pollution mixes with fog. For example, London, England, is often very foggy.Most people in London used to heat their homes by burning coal.ondon used to have a lot of smog. There is a special kind of smog called photochemical smog. It forms when photons of sunlight hit molecules of different kinds of pollutants in the atmosphere. The photons make chemical reactions happen. The pollution molecules turn into other kinds of nasty chemicals.

- ----   Smog is not all ozone.   Originally smog was a combination word for smoke and fog frequently seen in cities where coal was burned (e.g. London England.)   The name was then applied in the 1950's to what is more technically called photochemical smog.

Difference Between Industrial Smog & Photochemical Smog Both industrial smog and photochemical smog are forms of air pollution. Although both appear to the eye as yellow-brown haze, they differ in two key ways: chemistry and composition.

Smog Photochemical smog was first described in the 1950s. It is the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles and ground-level ozone. This noxious mixture of air pollutants may include the following:oinage of the term smog is generally attributed to Dr. Henry Antoine Des Voeux in his 1905 paper, Fog and Smoke for a meeting of the Public Health Congress.

Santa Monica Auto Service If your car was made prior to 2000, a smog check will consist of a test using the Emissions Inspection System (EIS). The system measures your vehicle's emissions under various conditions. The most common auto pollutants are carbon monoxide (CO), nitrous oxide (NO), and hydrocarbons (HCs). If the test shows any of these chemicals to be outside federal or state guidelines or the car’s sensors are not functioning, the vehicle fails the smog check.

- The necessary ingredients for photochemical smog formation are (1) nitrogen oxides, (2) sunlight, and (3) hydrocarbons. Photochemical smog formation proceeds through a sequence of reactions, all involving a free radical mechanism.

- Unfortunately, pollution is creating two ozone-related problems: 1  Certain pollutants deplete ozone in the stratosphere, exposing us to unhealthy levels of ultraviolet radiation. 2  Human-related emissions are spurring the formation of harmful ground-level ozone, which is a major contributor to smog.

Particulates The composition of particulate matter that generally causes visual effects such as smog consists of sulfur dioxide, nitrogen oxides, carbon monoxide, mineral dust, organic matter, and elemental carbon also known as black carbon or soot.

Acid Rain Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
