Quick Answer: Is Radon A Primary Pollutant?

Radon is a colorless, odorless gas, the primary source of indoor air pollution. Radon gas, along with decay products that can attach to dust and airborne particles, enters the lungs and decays, producing alpha and beta radiation that damages DNA and causes lung cancer.

What type of pollutant is radon?

Radon is a radioactive gas that has no smell, colour or taste. Radon is produced from the natural radioactive decay of uranium, which is found in all rocks and soils. Radon can also be found in water. Radon escapes from the ground into the air, where it decays and produces further radioactive particles.

What are the 6 primary pollutants?

These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.

What are the 4 primary pollutants?

Primary pollutants include carbon monoxide, oxides of nitrogen, sulfur oxides, volatile organic compounds (VOCs) and particulate pollution such as dust, ash or salt particles.

What is the main primary pollutant?

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.

Why Is radon a primary pollutant?

Radon is a colorless, odorless gas, the primary source of indoor air pollution. Radon results from the radioactive decay of radium in the soil, and it further decays to produce radioactive daughters including polonium and lead.

Is radon a secondary pollutant?

Radon, perfumes, noxious odors can also be considered pollutants. Secondary – Formed when primary pollutants react or combine with one another, or the basic elements.

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.

Is carbon dioxide a pollutant?

In its decision, the EPA stressed that it considers CO2 and other so-called greenhouse gases to be pollutants because of their role in propagating climate change, not because of any direct health effects.

What are secondary and primary pollutants?

Definition: A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.

Is sulfur dioxide a secondary pollutant?

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 sulfur dioxide a primary pollutant?

Primary pollutants, the beginning of the chain It is a precursor of CO2 and ozone. Sulfur dioxide (SO2), which reaches the atmosphere mainly as a consequence of human activities such as the burning of coal or oil. Natural sources such as volcanoes also contribute a remarkable percentage.

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.

What are the 3 primary pollutants?

Primary Pollutants

  • carbon monoxide (CO) odorless, colorless, poisonous gas.
  • oxides of nitrogen (NOx, NO) NO – nitric oxide.
  • sulfur oxides (SOx) SO2 – sulfur dioxide.
  • volatile organic compounds (VOCs) highly reactive organic compounds.
  • particulate matter (dust, ash, salt particles) bad for your lungs.

Which is not a primary pollutant?

1. Which of these is NOT a primary pollutant? Explanation: 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.

Which of the following pollutants are considered primary pollutants?

Types of primary pollutants include: Nitrogen oxides (NOx) Carbon monoxide (CO) Volatile organic compounds (VOCs)
