Is troposphere ozone a secondary pollutant?
Tropospheric ozone (O3) is a secondary pollutant that results from photochemical reactions of NOx and VOCs involving generally well-understood reactions (Jenkins and Clemitshaw, 2000).
Is 03 a secondary pollutant?
Ground-level ozone (O3) is not emitted directly from anthropogenic sources. It is a “secondary” pollutant formed by a complicated series of chemical reactions in the presence of sunlight.
Is CFC a secondary pollutant?
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).
Which of the following is called the secondary air pollutant?
3. Which of the following is called the secondary air pollutant? Sol: (b) Ozone.
Is so2 a secondary pollutant?
Sulfur dioxide is also a natural byproduct of volcanic activity. 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 n2o a primary or secondary pollutant?
The amount of nitrogen oxides emitted into the atmosphere as air pollution, from both man-made sources, can be quite significant. It’s mainly produced by road traffic and energy production. While NO2 is a primary pollutant, it is also a contributing component for secondary pollutants formed from a chemical reaction.
Is NO2 a secondary pollutant?
Though nitrogen dioxide can be a primary pollutant, it’s mostly a concern as a secondary pollutant. As a primary pollutant, NO2 is emitted in limited amounts through vehicles into the air. Nitrogen dioxide is also a secondary pollutant because it can be formed through oxidisation.
Is carbon dioxide a secondary pollutant?
Carbon Monoxide (CO) Carbon monoxide is released from volcanoes and forest fires as well. Secondary pollutants like ozone and carbon dioxide (CO2), a greenhouse gas, come from carbon monoxide.
Is ozone a pollutant in the stratosphere?
In the stratosphere, ozone protects life on Earth from the sun’s ultraviolet radiation. In contrast, at lower levels, it is an important greenhouse gas and air pollutant, which is harmful to human and ecosystem health. It is also a major component of urban smog.
Is DDT a secondary pollutant?
DDT is a secondary pollutant. Primary pollutants persist in the form they are released in the environment. Secondary pollutants are formed by reaction amongst the primary pollutants. Secondary pollutant are more toxic than primary pollutants.
