What pollutant is colorless odorless gas that is a naturally occurring decay product of uranium?
|Radon in the periodic table|
What is a gaseous decay product of uranium that is found in rocks?
Radon (chemical symbol Rn) is an odorless, colorless, radioactive gas. It comes from the natural decay of uranium and radium found in nearly all rocks and soils. Radon can move up from the ground into buildings through openings in floors or walls that are in contact with the ground.
What is emitted from most manufactured building materials and furniture?
VOCs are emitted by many commonplace products, including paints, sprays, varnishes, cleaning products, air fresheners, building materials and furnishings.
What are the three main anthropogenic sources of gaseous air pollutants in the United States?
What are the three main anthropogenic sources of gaseous air pollutants in the US? gaseous air pollutants in the US are industry, transportation, and energy production.
Which of the following environmental problems is most often linked to the combustion of fossil fuels?
When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.
What is the major source of radon in houses in the United States?
It comes from the natural breakdown of uranium in soil, rock, and water and gets into the air you breathe. Radon typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Radon can also enter your home through well water.
What is radon made of?
Radon comes from the breakdown of naturally-occurring radioactive elements (such as uranium and thorium) in soils and rocks. As part of the radioactive decay process, radon gas is produced.
What kind of decay is radon?
Radon undergoes radioactive decay, when it releases ionizing radiation and forms “daughter” elements, known as decay products. It is the release of radiation from this decay process that leads to exposure and health risks from radon.
What radiation does radon gas emit?
The radioactive elements formed by the decay of radon can be inhaled and enter our lungs. Inside the lungs, these elements continue to decay and emit radiation, most importantly alpha particles. These are absorbed by the nearby lung tissues and cause localised damage. This damage can lead to lung cancer.
Which of the following pollutants is an example of a secondary pollutant quizlet?
Smog is an example of a secondary pollutant.
Which of the following is most closely associated with the depletion of stratospheric ozone?
Chlorofluorocarbons (CFCs) cause significantly stratospheric ozone depletion and global warming relating to the greenhouse effect.
Why did the Do After one week decrease as the amount of waste increased?
To observe the effect of organic waste on DO. Why did the DO after one week decrease as the amount of waste increased? The algae multiplied and then died and decomposed.
Which of the following material is anthropogenic?
Anthropogenic sources such as domestic and industrial waste water effluents, urban and agricultural runoff, fossil fuel combustion, atmospheric deposition, and antifouling paints from ships (mainly tin and copper) can increase metal concentrations in marine environments to higher than background levels.
What is anthropogenic pollutant?
Introduction. Anthropogenic contaminants (ACs) are substances found in the environment due to human activities (Rhind, 2009), and can effects the living organisms, directly or indirectly.
What are pollutants called?
Under the Clean Air Act, the National Ambient Air Quality Standards (NAAQS) are developed by the Environmental Protection Agency (EPA) for six common air pollutants, also called “criteria pollutants”: particulates
smog and ground-level ozone
Which of the following pollutants are emitted by burning of fossil fuel?
Which of the following pollutants are emitted by the burning of fossil fuel? Explanation: Fossil fuels generate Oxides of Carbon like CO and CO2, Oxides of Nitrogen like NO and NO2, and Oxides of Sulphur like SO2 and SO3. Apart from that particulate matter and heat is also generated by fossil fuels.
What types of pollution are caused by fossil fuels?
Air pollution: Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, all of which are harmful to the environment and human health (as discussed in the health section below).
Which of the following environmental problems is most often linked to the combustion of fossil fuels quizlet apes?
Which of the following describes a step in the generation of electricity using fossil fuels that can most directly lead to an environmental problem? One of the products of burning fossil fuel is carbon dioxide, a greenhouse gas that can cause increased global warming when released into the atmosphere.
What are some common compounds of radon?
Radon fluoride (RnF) is the only confirmed compound of radon.
Where is radon most likely found?
Radon gas is a ubiquitous element found in rock and soil. The burning of coal and other fossil fuels also releases radon. When radon escapes from soil or is discharged from emission stacks to the outdoor air, it is diluted to levels that are normally, but not always, lower than indoor air.
What causes radon in basement?
Know what causes radon in basements
Radon comes from decaying Uranium that is contained in the rock and soil beneath the basement (under the foundation) of every home. Being in constant contact with the ground, a home’s basement is the main entry point for Radon gas.
What does radon cause?
Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked.
Is radon toxic?
It can be in the air around you, but it’s usually in very small amounts that aren’t harmful. Large amounts of radon cause health problems. Even though it’s a natural gas that comes from the earth, it can be toxic if you breathe in a lot of it over a long time.
What type of radiation is radium?
Radium emits alpha particles (two protons and two neutrons bonded together), beta particles (high energy electrons or positrons), and gamma rays (the most energetic wavelength of light), according to New World Encyclopedia.
What does radon release?
Radon is a colorless, odorless gas, a radioactive byproduct of radium. It is part of the natural radioactive decay series starting with uranium-238. It is radioactive with a half-life of 3.8 days, decaying by the emission of alpha particles to polonium, bismuth, and lead in successive steps.
