Often asked: Is Cigarette Smoke A Primary Or Secondary Pollutant?

These primary pollutants sometimes react with other chemicals in the air to produce secondary pollutants. Examples include household products and chemicals, out-gassing of building materials, allergens (cockroach and mouse dropping, mold, pollen), and tobacco smoke.

Is smoke from fires a primary or secondary pollutant?

Primary sources cause particle pollution on their own. For example, wood stoves and forest fires are primary sources. Secondary sources let off gases that can form particles. Smoke from fires and emissions (releases) from power plants, industrial facilities, and cars and trucks contain PM2.5.

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.

Which pollutant is present in cigarette smoke?

The correct answer is Carbon monoxide.

Is smog primary or secondary?

Secondary pollutants are concerning as they can be formed from many different compounds. 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.

What are examples of secondary pollutants?

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 examples of primary pollutants?

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.

Which one is not an example of primary pollutants?

Ozone 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. Similarly, sulphuric acid is also not a primary pollutant.

Are CFCS primary or secondary pollutants?

The major primary pollutants are Oxides of Sulphur, Oxides of Nitrogen, Oxides of Carbon, Particulate Matter, Methane, Ammonia, Chlorofluorocarbons, Toxic metals etc. The secondary pollutants are not emitted directly.

What are 5 primary air pollutants?

5 Major Outdoor Air Pollutants

  • Ozone (O3)
  • Nitrogen Oxides (NOx)
  • Carbon Monoxide (CO)
  • Sulfur Dioxide (SO2)
  • Particulate Matter (PM10 and PM2.5)

What gases are in cigarette smoke?

The gas phase of cigarette smoke includes nitrogen (N2), oxygen (O2), carbon dioxide (CO2), CO, acetaldehyde, methane, hydrogen cyanide (HCN), nitric acid, acetone, acrolein, ammonia, methanol, hydrogen sulfide (H2S), hydrocarbons, gas phase nitrosamines, and carbonyl compounds (Borgerding and Klus 2005; Rodgman and

Is nicotine a pollutant?

Cigarette butts cause pollution by being carried, as runoff, to drains and from there to rivers, beaches and oceans. Preliminary studies show that organic compounds (such as nicotine, pesticide residues and metal) seep from cigarette butts into aquatic ecosystems, becoming acutely toxic to fish and microorganisms.

Is nicotine an air pollutant?

In addition, personal sampling was conducted by carrying backpacks, reflecting breathing zone exposure of convention attendees. Our study confirms that e-cigarette aerosol is a major source of indoor air pollution of PM10, TVOCs, and air nicotine, which impairs indoor air quality.

Which is not a 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.

Is industrial smog a secondary pollutant?

While industrial smog’s primary pollutants of coal and fossil fuels mixing with dense water vapor are widely understood, the creation of secondary pollutants — the ones created when primary pollutants react with substances normally found in the atmosphere — is the root of most of the human health problems.

Is smog a secondary pollutant?

Smog is an example of a secondary pollutant.
