What is sulfuryl fluoride used for?
Sulfuryl fluoride is a structural and commodity fumigant used to control a wide variety of pests, including termites, powder post beetles, old house borers, bedbugs, carpet beetles, moths, cockroaches, rats and mice.
Which gas is the main pollutant responsible for global warming?
Carbon dioxide (CO2)
Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2020, CO2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities.
Which of the following gas is called greenhouse gas?
Carbon dioxide
Carbon dioxide is called a greenhouse gas because it is one of the gases in the atmosphere that warms the Earth through a phenomenon called the greenhouse effect. Carbon dioxide molecules in the atmosphere absorb long-wavelength infrared energy (heat) from the Earth and then re-radiate it, some of it back downward.
Which of the following gases has the highest radiative efficiency?
Perfluorotributylamine
Which of the following gases has the highest radiative efficiency? Explanation: Perfluorotributylamine used as in heat transfer and electrical industry has the highest radiative efficiency, i.e. it can effectively trap the long wave radiation better than other greenhouse gases.
Is sulfuryl fluoride a greenhouse gas?
Sulfuryl fluoride (SO2F2) is a potent greenhouse gas that has been used increasingly in fumigation since the global phase-down in the nonquarantine/preshipment use of methyl bromide under the Montreal Protocol.
Where does sulfuryl fluoride come from?
It can be prepared by direct reaction of fluorine with sulfur dioxide: SO2 + F2 → SO2F. On a laboratory scale, sulfuryl fluoride has been conveniently prepared from 1,1′-sulfonyldiimidazole, in the presence of potassium fluoride and acid.
What are the two common pollutants responsible for global warming?
Q: What causes global warming? A: Global warming occurs when carbon dioxide (CO2) and other air pollutants collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface.
Which greenhouse gas has the lowest global warming potential?
Despite carbon dioxide’s comparatively low GWP among major greenhouse gases, the large human-caused increase in its atmospheric concentration has caused the majority of global warming….Source.

What gases have the lowest global warming potential?
According to the California Air Resources Board, that would be R-717, which has a 100-year GWP of 0. R-717 goes by the trade name Ammonia, which has been around since the 1930s. Experts today recognize it as the most efficient refrigerant in the world.
What is Vikane gas used for?
To solve this problem, sulfuryl fluoride, the active ingredient of Vikane® fumigant, was developed to be used exclusively by professional fumigators for structural fumigation. Vikane is also used to control bed bugs, cockroaches, clothes moths, rodents, spiders, carpet beetles and other structure-infesting pests.
What gas is used to fumigate termites?
sulfuryl fluoride
Structural fumigations for termite extermination are conducted by the thousands annually in the United States. The active chemical commonly used is sulfuryl fluoride, an odorless gas that targets the nervous system.
How toxic is sulfuryl fluoride?
* Sulfuryl Fluoride can cause nausea, vomiting, diarrhea, abdominal pain and loss of appetite. * Repeated high exposure can cause weakness, muscle twitching, seizures and convulsions. * Sulfuryl Fluoride may damage the liver and kidneys.
Is O2 a greenhouse gas?
O2 and N2 are not greenhouse gases. All molecules of three or more atoms are infrared active. A greenhouse gas has a stronger impact on the radiative balance of the earth if it interacts with light in the middle of the earth-light spectrum.

Which of the following has lowest global warming potential?
The period usually used for GWPs is 100 years. So, among all the gases since GWP is compared to CO2; CO2 has the least GWP i.e. 1.
