What is the main source of industrial smog?
Industrial Smog Sources Coal-burning power plants and factors are by far the leading source of the chemicals that cause industrial smog, according to the Union of Concerned Scientists. A single coal power plant produces more than 7,000 tons of sulfur dioxide per year, even with state-of-the-art pollution control.
Which is the main component of smog?
tropospheric ozone Smog, formed mainly above urban centres, is composed mainly of tropospheric ozone (O3); primary particulate matter such as pollen and dust; and secondary particulate matter such as sulphur oxides, volatile organic compounds, nitrogen oxides (NOx) and ammonia gas.
What are the main components of industrial smog and photochemical smog?
It is produced when nitrogen oxides and volatile organic compounds in automobile and fossil-fueled power-plant emissions combine with oxygen in the air in direct sunlight. Whereas industrial smog casts a gray pallor over the areas it affects, the nitrogen dioxide in photochemical smog creates a dingy, brownish haze.
What is the major harmful component of industrial smog?
Airborne nitrogen compounds, especially nitrogen oxides, contribute to the formation of air pollutants like smog, which can restrict visibility and affect human health. Ground-level ozone is the main component of smog.
What is industrial smog quizlet?
industrial smog. Type of air pollution consisting mostly of a mixture of sulfur dioxide, suspended droplets of sulfuric acid formed from some of the sulfur dioxide, and a variety of suspended solid particles. Compare photochemical smog.
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 industrial smog?
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.
What are the effects of industrial smog?
When inhaled, smog irritates our airways, increasing our risk of serious heart and lung diseases. These health risks are why many cities monitor smog levels. On a high ozone-alert day, for example, your eyes and throat may burn, and you may cough and wheeze.
What is the main component of industrial smog quizlet?
Complex mixture of air pollutants produced in the lower atmosphere by the reaction of hydrocarbons and nitrogen oxides under the influence of sunlight. Especially harmful components include ozone, peroxyacyl nitrates (PANs), and various aldehydes. Compare industrial smog.
Is co2 a component of photochemical smog?
Photochemical smog only occurs in presence of sunlight. Carbon dioxide is a greenhouse gas and hence it's concentration in atmosphere does not increase the smog.
Does industrial smog have primary pollutants?
Apparently, this is a logically depiction given that the main source of industrial smog was from the burning of coal for heat and energy (Nebel and Wright 527). As a result, the main pollutant of industrial smog is sulfur dioxide-a compound largely responsible for acid precipitation.
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.
Is smog a primary or secondary pollutant?
Smog is an example of a secondary pollutant.
Is SO2 components 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.
Which is the major pollutants present in photochemical smog?
The two major primary pollutants, nitrogen oxides and VOCs, combine to change in sunlight in a series of chemical reactions, outlined below, to create what are known as secondary pollutants. The secondary pollutant that causes the most concern is the ozone that forms at ground level.
What are the components of photochemical smog?
The major undesirable components of photochemical smog are nitrogen dioxide (NO2), ozone (O3), PAN (peroxyacetylnitrate), and chemical compounds that contain the –CHO group (aldehydes). PAN and aldehydes can cause eye irritation and plant damage if their concentrations are sufficiently high.
What is the main component of photochemical smog quizlet?
nitrogen oxide (NO) and nitrogen dioxide (NO2) collectively. These gases play a role in photochemical smog. colorless and highly reactive gas; a major component of photochemical smog and also found in the stratosphere where it protects life by filtering out most harmful UV radiation from the sun.
What are the major components of smog and how does it form quizlet?
Terms in this set (5) Smog forms when sunlight, nitrogen oxides, and volatile organic compounds are present. The secondary pollutant ozone is a major component of photochemical smog. Sulfur is the dominate ingredient in sulfurous smog. Smog impairs respiratory function in human beings.
Which gas is commonly found in smog quizlet?
Nitrogen oxide (NO) and nitrogen dioxide (NO2) collectively. These gases play a role in photochemical smog and can irritate the eyes, nose, throat, and lungs; aggravate asthma and bronchitis; and increase susceptibility to respiratory infections by impairing the immune system.
What is the main component of smog quizlet?
The key component of smog is —-ground-level ozone.
Which of the following is the main component of smog quizlet?
What are the major components of smog? When and how does smog form in Los Angeles? nitrogen oxides (largely from automobile exhaust), volatile hydrocarbons, and oxygen in the atmosphere to produce ground-level ozone; this reaction requires solar energy.
