Secondary pollutants include Sulfuric acid (H2SO4) which
can cause respiratory problems
. Nitrogen dioxide (NO2) which gives air a brownish coloration. … Acid rain which is caused by sulfuric and nitric acids. They are created by burning fossil fuels and some industrial processes.
Is sulfate a primary or secondary pollutant?
Most sulfate is a
secondary pollutant
, formed by the oxidation in the atmosphere of sulfur dioxide gas.
Why is acid rain a secondary pollutant?
Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed
when sulfur dioxide or nitrogen oxides react with water
.
Which of the following pollutant is secondary pollutant?
Secondary pollutants are not emitted directly. They are formed from the combination of primary pollutants with some other compound. Examples of secondary pollutants are
Ozone, Formaldehyde, PAN (peroxy acetyl nitrate)
and Smog etc.
What is secondary pollution?
Secondary air pollution is
pollution caused by reactions in air already polluted by primary emissions
(from factories, automobiles and so forth). An example of secondary air pollution is photochemical smog.
Is Pan a secondary pollutant?
Peroxyacetyl nitrate (PAN) and ozone are the two important
secondary photochemical air
pollutants found in the urban at- mosphere (1-3). Of the two, PAN is the more useful indicator of photochemical reactions in polluted air as, unlike ozone, it appears to have no large natural source (2-7).
Is co2 a secondary pollutant?
Carbon Monoxide (CO)
Carbon monoxide is released from volcanoes and forest fires as well.
Secondary
pollutants like ozone and carbon dioxide (CO
2
), a greenhouse gas, come from carbon monoxide.
Is sulfuric acid a secondary pollutant?
Secondary pollutants
include Sulfuric acid (H2SO4) which can cause respiratory problems. Nitrogen dioxide (NO2) which gives air a brownish coloration. … Acid rain which is caused by sulfuric and nitric acids. They are created by burning fossil fuels and some industrial processes.
Is nitric acid a secondary pollutant?
Different types of secondary pollutants include: Ozone (O
3
) Sulfuric acid and nitric acid (component of
acid rain
)
Is acid rain still a problem in 2020?
The quick version: Yes, acid rain is still around, and
yes it’s still a problem
. … Rain is naturally slightly acidic, since picks up carbon dioxide in the air, producing carbonic acid. But when it starts absorbing industrial pollutants like sulfur dioxide and nitrogen oxide, the acidity becomes troublesome.
What is primary and secondary pollutants with example?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are
particulates, carbon monoxide, nitrogen oxide, and sulfur oxide
. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
Is formaldehyde a secondary pollutant?
Finally, it should be noted that
secondary formation
of formaldehyde occurs in air through the oxidation of volatile organic compounds (VOCs) and reactions between ozone (mainly from outdoors) and alkenes (especially terpenes) have been widely described.
Which one of the following is not secondary pollutant?
Smog
is not a secondary pollutant. Smog is air pollution that reduces visibility. The term “smog” was first used in the early 1900s to describe a mix of smoke and fog. The smoke usually came from the burning of coal.
Why is pan a secondary pollutant?
Figure 1 shows the structure of an example of PAN. PANs are a secondary pollutant
since they form in the atmosphere after the emission of primary pollutants
. Sources of the pollutants required to create PANs include motor vehicles, tobacco smoke, and the burning of fossil fuels.
Which of the following is secondary pollutant co2 no3?
Answers (3)
O
3
(ozone)
is a secondary pollutant. These are formed by the reaction of primary pollutant.
What is the relationship between carbon dioxide and secondary pollutant?
Secondary pollutants are
formed when primary pollutants interact with each other in the atmosphere
. Carbon monoxide (CO) is a colourless, odourless, and very poisonous gas. It is formed as a by-product of incomplete combustion processes involving carbon based energy sources, such as the burning of petrol, coal or wood.
