Is acid rain a primary pollutant?
Is acid rain a primary 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.
What are the primary and secondary air pollutants?
The major primary pollutants are Oxides of Sulphur, Oxides of Nitrogen, Oxides of Carbon, Particulate Matter, Methane, Ammonia, Chlorofluorocarbons, Toxic metals etc. Most important secondary level Air Pollutants are Ground Level Ozone, Smog and POPs (Persistent Organic Pollutants).
What is a secondary pollutant?
Secondary pollutants are defined as pollutants in our environment that are formed when other primary pollutants interact with the atmosphere.
Which among the following is a secondary pollutant?
Here Ozone is secondary pollutant.
Is oxygen a secondary pollutant?
The phenomena of photochemical smog (seen in high density cities, see Figure 1) is a result of the interactions of primary pollutants with other molecules in the air such as molecular oxygen, water and hydrocarbons. Different types of secondary pollutants include: Ozone (O3)
Which one of the following is not a secondary pollutant?
Smog is not a secondary pollutant.
Is DDT a secondary pollutant?
Q. Assertion : Secondary air pollutants are formed by interaction among the primary pollutants and are more toxic. Reason : DDT is a secondary air pollutant.
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.
Is radon primary or secondary pollutant?
Radon is a colorless, odorless gas, the primary source of indoor air pollution.
Is carbon monoxide a primary or secondary pollutant?
Secondary pollutant form when primary pollutants emitted directly from a combustion process react in the atmosphere. Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide.
Is HNO3 a secondary pollutant?
Nitric acid (HNO3) is a secondary pollutant formed in the troposphere primarily from the oxidation of NOx (NOx = NO + NO2) emitted from vehicle tailpipes and other combustion sources (for example, power generation).
What is primary and secondary pollution attributed to?
Primary pollutants and secondary pollutants can be more dangerous. The first are those that are emitted directly from a source, which can be natural (volcanic eruptions or fires, for example) or of anthropogenic origin (carbon monoxide from vehicles). Secondary pollutants, on the other hand, are not emitted directly.
Is so2 primary or secondary?
Like nitrogen dioxide, sulfur dioxide can create secondary pollutants once released into the air. Secondary pollutants formed with sulfur dioxide include sulfate aerosols, particulate matter, and acid rain.
Is sea salt a primary or secondary pollutant?

Is pollen a primary or secondary pollutant?
sources are the primary sources for these pollutants. particles and liquid droplets that are small enough to remain suspended in the air. pollen, etc. It also includes tiny liquid droplets of sulfuric acid, oil, and various pesticides.
Is radon gas a primary or secondary pollutant?
How can we prevent secondary pollutants?
Personal exposure to ambient air pollution can be reduced on high air pollution days by staying indoors, reducing outdoor air infiltration to indoors, cleaning indoor air with air filters, and limiting physical exertion, especially outdoors and near air pollution sources.
Is water vapor a secondary pollutant?
Secondary pollutants are created in the atmosphere when primary pollutants have chemical reactions with each other or other atmospheric compounds, such as water vapour. Secondary pollutants include particulate matter and ozone.
