- Smog usually is produced through a complex set of photochemical reactions involving volatile organic compounds (VOC's) and nitrogen oxides in the presence of sunlight that result in the production of ozone.

Coal and the Environment Several principal emissions result from coal combustion: 1  Sulfur dioxide (SO2), which contributes to acid rain and respiratory illnesses. 2  Nitrogen oxides (NOx), which contribute to smog and respiratory illnesses. 3  Particulates, which contribute to smog, haze, and respiratory illnesses and lung disease.

Smog Modern smog, as found for example in Los Angeles, is a type of air pollution derived from vehicular emission from internal combustion engines and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog.mog is a serious problem in many cities and continues to harm human health. Ground-level ozone, sulfur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma.

The Dangers of Smog: What You Need to Know About Air Pollution Because of the effects of ozone on your lungs, smog exposure may lead to several different types of short-term health problems: 1  Coughing and throat/chest irritation: High levels of ozone can irritate your respiratory system.mog contains a health-harming pollutant called ozone. Elevated levels of ozone have been shown to cause a variety of negative health effects in the lungs. Smog is most common in big cities; however, even those who live in suburban areas need to be conscious of its dangers.

What is Smog? Smog is basically derived from the merging of two words; smoke and fog. Smog is also used to describe the type of fog which has smoke or soot in it.Smog is a yellowish or blackish fog formed mainly by a mixture of pollutants in the atmosphere which consists of fine particles and ground level ozone.Smog which occurs mainly because of air pollution, can also be defined as a mixture of various gases with dust and water vapor.t is purely caused by air pollution. Ground level ozone and fine particles are released in the air due to complex photochemical reactions between volatile organic compounds (VOC), sulphur dioxide (SO 2) and nitrogen oxides (NO x). These VOC, SO 2 and NO x are called precursors.

What are some pollutants produced by the burning of fuels? In addition, total suspended particulates contribute to air pollution, and nitrogen oxides and hydrocarbons can combine in the atmosphere to form tropospheric ozone, the major constituent of smog. Carbon monoxide is a gas formed as a by-product during the incomplete combustion of all fossil fuels.Exposure to carbon monoxide can cause headaches and place additional stress on people with heart disease.ulfur oxides are produced by the oxidization of the available sulfur in a fuel. Utilities that use coal to generate electricity produce two-thirds of the nation's sulfur dioxide emissions. Nitrogen oxides and sulfur oxides are important constituents of acid rain.

The Sources of Smog The Sources of Smog. by Matt Osborne 231 Comments. Hydrocarbons and nitrogen oxides come from a great variety of industrial and combustion processes. In typical urban areas, at least half of those pollutants come from cars, buses, trucks, and off-highway mobile sources such as construction vehicles and boats.

- Noxious sulfur dioxide gas and other pollutants emitted from Kilauea Volcano on the Island of Hawai`i react with oxygen and atmospheric moisture to produce volcanic smog (vog) and acid rain.hen the magma rises toward the surface, where pressure is lower, the gas bubbles out and escapes. Air pollution caused by SO 2 and other gases emitted from Kilauea became a frequent problem on the Island of Hawai`i in 1986.

What Is Smog? Post. Share. 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.While ozone in the stratosphere protects earth from harmful UV radiation, ozone on the ground is hazardous to human health.ne of the primary components of photochemical smog is ozone.

Sulfur Dioxide Chemical reference number (CAS). Sulfur dioxide, SO 2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead and iron) that contain sulfur.Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfuric acid is a major component of acid rain.eople who live near industrial sources of sulfur dioxide may be exposed to it in the air. You are most likely to be exposed if you work in industries where SO2 is produced, such as copper smelting or power plants, or where SO2 is used like the production of sulfuric acid, paper, food preservatives or fertilizers.

- / 0 comments. Photochemical smog is produced when sunlight is mixed with various pollutants like nitrogen dioxide or hydrocarbons. It is unique type of smog that was first spotted in 1950. The photochemical smog is often colorless and invisible.However, it can cause various problems like eye irritation, respiratory problems and so on. photochemical smog is essentially a chemical reaction between sunlight, volatile organic compounds, nitrogen oxides, which forms into a new kind of 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.ccording to the U.S. Environmental Protection Agency, photochemical smog is a mixture of pollutants that form when nitrogen oxides and volatile organic compounds react to sunlight, creating a haze that is common over cities.

Until that time, the volcano's ongoing eruption, which began in 1983, consisted of short, spectacular episodes of lava fountaining about once every 3 weeks.

Photochemical smog Formation. Photochemical smog forms from a complex process, however the source of it is quite apparent. The largest contributor is automobiles, while coal-fired power plants and some other power plants also produce the necessary pollutants to facilitate its production.

The Causes and Effects of Smog As traffic and other sources add more pollutants to the air, the smog gets worse. Ironically, smog is often more severe farther away from the sources of pollution, because the chemical reactions that cause smog take place in the atmosphere while pollutants are drifting on the wind.

- When VOCs are present, a complex series of reactions occurs that causes ozone to accumulate. These reactions increase the NO 2 sink in the atmosphere by consuming NO [through the reaction f described below], which then ceases to function as an ozone sink [reaction c]. NO 2 thus forms with no ozone destruction.

Air Pollution: Everything You Need to Know Smog, or “ground-level ozone,” as it is more wonkily called, occurs when emissions from combusting fossil fuels react with sunlight. Soot, or “particulate matter,” is made up of tiny particles of chemicals, soil, smoke, dust, or allergens, in the form of gas or solids, that are carried in the air.

- 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.

How does photochemical smog differ from industrial smog? Industrial smog occurs when the smoke and sulfur dioxide produced from burning coal merges with fog and creates a yellowish-brown-colored haze close to ground level. Photoch … emical smog forms as the result of increased usage of all fossil fuels, including gasoline and the burning of trees and organic waste.

The Causes and Effects of Smog The term smog was first used in London during the early 1900's to describe the combination of smoke and fog. What we typically call smog today is a mixture of pollutants but is primarily made up of ground-level ozone. Ozone can be beneficial or harmful depending on its location.
