Which One Of The Following Is Not A Secondary Pollutant?

What is a secondary air pollutant?

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..

What are examples of primary and secondary pollutants?

Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

What is the difference between primary and secondary pollutants quizlet?

What is the difference between primary and secondary pollutants? Primary pollutants are harmful substances emitted directly into the air. Secondary pollutants are formed when primary pollutants react with one another or with the basic components of air to form new harmful pollutants.

Which is more harmful primary or secondary pollutants?

2) Which are more harmful primary or secondary pollutants? Ans- They emit carbon monoxide which is one of the biggest contributors (by weight) to air pollution. Though these statistics are horrifying, secondary pollutants can be more harmful and severe to human health than primary pollutants.

Which of the following is a primary pollutant?

A primary pollutant is an air pollutant emitted directly from a source e.g., carbon monoxide (CO), oxides of nitrogen (NOx, NO), sulfur oxides (SOx), SO2, volatile organic compounds (VOCs) and particulate matter (dust, ash, salt particles).

What are three secondary pollutants?

Secondary pollutantOzone (O3)Sulfuric acid and nitric acid (component of acid rain)Particulate matter.Nitrogen dioxide (NO2)Peroxyacyl nitrates (PANs)and more.

Is co2 a secondary pollutant?

Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

What are primary and secondary pollutants give examples?

The difference between them is how they are formed.Primary Pollutants. Primary pollutants come right from the source. … Secondary Pollutants. … Ground Level Ozone (Photochemical Smog) … Acid Rain. … Nitrogen Dioxide.

Which of the following is not primary pollutant?

OzoneOzone is not a primary pollutant since it is formed by the photo-chemical reaction of oxygen with the UV rays and not directly discharged into the atmosphere by a source.

Which is not a secondary pollutant?

Primary pollutants are directly emitted from the sources. Examples of primary pollutants are carbon monoxide, carbon dioxide, sulphur dioxide and benzene etc. Secondary pollutants are not emitted directly. … Examples of secondary pollutants are Ozone, Formaldehyde, PAN (peroxy acetyl nitrate) and Smog etc.

Which one of the following is 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.

Is Mercury a primary or secondary pollutant?

Primary pollutants come directly from sources such as industrial facilities, automobiles and forest fires. These include sulfur and nitrogen compounds, particulate matter, volatile organic compounds such as paint fumes and solvents, and toxic metals such as mercury.

What is an example of a secondary pollutant quizlet?

Smog is formed by chemical reactions that involve sunlight, air, automobile exhaust, and ozone. Smog is an example of a secondary pollutant.

Is h2so4 a secondary pollutant?

Secondary pollutants include Sulfuric acid (H2SO4) which can cause respiratory problems. Nitrogen dioxide (NO2) which gives air a brownish coloration. Ozone (O3) which is a colorless gas, has a sweet smell, is an oxidizing agent, and causes irritation to the eyes.

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). … Once formed, HNO3 is lost primarily by wet and dry deposition.

What contributes most to acid precipitation quizlet?

What contributes most to acid precipitation? As a lake becomes more acidic, fish are harmed not only by the acidity but also by substances that leach out of the soil into the water.
