The Causes and Effects of Smog Smog-forming pollutants come from many sources, such as automobile exhausts, power plants, factories, and many consumer products, including paints, hair spray, charcoal starter fluid, solvents, and even plastic popcorn packaging.

What causes photochemical smog? It can also harm plants and other living things. Photochemical smog is formed by the action of sunlight on pollutants such as hydroc … arbons and nitrogen oxides. these chemicals react to form a brownish mixture of ozone and other pollutants.

smog smog (smŏg) 1. A form of air pollution produced when sunlight reacts with hydrocarbons and nitrogen compounds released into the atmosphere, especially from automobile exhaust. Smog is common in many large cities, especially during hot, sunny weather. It appears as a brownish haze and can irritate the eyes and lungs.

- 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.

Air pollution Secondary pollutants include: 1  Particulates created from gaseous primary pollutants and compounds in photochemical smog. Smog is a kind of air pollution. Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide.

Air Pollution: Everything You Need to Know The EPA’s “Plain English Guide to the Clean Air Act” states, “In many parts of the United States, pollution has reduced the distance and clarity of what we see by 70 percent.” The sources of smog and soot are similar.

The Sources and Solutions: Fossil Fuels The Sources and Solutions: Fossil Fuels Cars and trucks release nitrogen into the atmosphere, which contributes to nutrient pollution in our air and water. Airborne nitrogen pollution affects not only the quality of the air we breathe, but also the land and the water.

What causes smog? What causes photochemical smog? 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 s…moke and sulfur dioxide.

- Industrial smog forms when smoke and sulfur emissions, from coal burning, combine with fog, under the right conditions. While the release of large quantities of air pollutants can form industrial smog, other factors have an important role in the severity of a smog outbreak.

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.

Nonpoint Source Pollution The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack” (Hill, 1997). Factories and sewage treatment plants are two common types of point sources. Factories, including oil refineries, pulp and paper mills, and chemical, electronics and automobile manufacturers, typically discharge one or more pollutants in their discharged waters (called effluents).

Chemistry Some processes in modern technology, such as iron smelting, still produce carbon monoxide as a byproduct. Worldwide, the largest source of carbon monoxide is natural in origin, due to photochemical reactions in the troposphere that generate about 5 × 10 kilograms per year. Other natural sources of CO include volcanoes, forest fires, and other forms of combustion.

- Source of the Primary Pollutants-Photochemical Smog. 1  Mobile sources (such as automobiles) are the largest sources of CO to the atmosphere. 2  Stationary industrial sources are the largest source of particulate matter (PM).

Car Exhaust - Air Pollutants The most common form of air pollution in the San Antonio region is. ground-level ozone, a major component of smog. Ground-level. ozone forms readily in the atmosphere during warm, sunny days. Sunlight causes chemicals from the fuels we burn (e.g., gasoline. and diesel) and vapors from such products as gasoline and paint.

- 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 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 major sources for carbon dioxide emissions The major sources for carbon dioxide emissions. | Sourced From Helium |. Carbon dioxide is a common gas that comes from primarily natural sources, when a carbon atom combines with an oxygen molecule. It makes up a small, but important part of our atmosphere, which is primarily nitrogen and oxygen.

Nonpoint source pollution Urban and suburban areas are a main sources of nonpoint source pollution due to the amount of runoff that is produced due to the large amount of paved surfaces.

- Quick Answer. Air pollution comes from a wide range of sources, which are categorized into mobile, stationary, area and natural sources. Mobile sources include vehicles, trains and planes. Stationary sources include industries and oil refineries. Examples of area sources are cities and agricultural areas, while natural sources include volcanoes and wildfires.

Air Pollution - Its Nature, Sources, and Effects Area sources can also be thought of as non-point sources, such as construction of housing developments, dry lake beds, and landfills. Mobile Sources. A mobile source of air pollution refers to a source that is capable of moving under its own power.

The Causes and Effects of Industrial and Photochemical Smog Effects of Photochemical Smog. Photochemical smog's effects cause damage to the respiratory system and environmental systems with the release of nitrogen oxide (NO), ozone and volatile organic compounds (VOCs). These effects are worse when the sun is highest because the pollutants react with it.

What causes smog? Making the world better, one answer at a time. Smog is caused by many factors. The smog that enters the atmosphere consists of over 100 chemicals, many coming from different sources. Particulates present in smog include carbon monoxide, dirt, soot, dust, and ozone. To really create the smog effect, sunlight, hydrocarbons, and nitrogen oxides have to mix together.
