Is nitrogen oxide a primary or secondary pollutant?

Nitrogen dioxide and other nitrogen oxides react with other chemicals in the air to form other pollutants, known as secondary pollutants. These secondary pollutants include ozone, particulate matter, acid rain, and other toxic chemicals.

What is an example of a secondary air 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 type of reaction is initiated in the presence of nitrogen oxide?

Fundamental Studies of Biodiesel NOx Impact. NOx formation in diesel combustion occurs primarily via the thermal mechanism, where nitrogen from the combustion air is oxidized at a high temperature.

Which is a secondary air pollutant quizlet?

Secondary air pollutant is. carbon monoxide, nitrogen oxides, sulfur dioxide, volatile organic compounds, particulate matter. Examples of primary pollutant are. ground-level ozone.

Is ozone a secondary pollutant?

Ground-level ozone is a secondary pollutant – it is formed through chemical reactions of other molecules already in the air, specifically nitrogen oxides (NOx) and volatile organic compounds (VOCs).

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.

What can be reduced if air pollution?

Reduce the number of trips you take in your car. Reduce or eliminate fireplace and wood stove use. Avoid burning leaves, trash, and other materials. Avoid using gas-powered lawn and garden equipment.

How many people have died from air pollution this year?

4.6 million people
