What is the most common source of carbon monoxide group of answer choices?
The greatest sources of CO to outdoor air are cars, trucks and other vehicles or machinery that burn fossil fuels. A variety of items in your home such as unvented kerosene and gas space heaters, leaking chimneys and furnaces, and gas stoves also release CO and can affect air quality indoors.
What is source of carbon monoxide?
Carbon Monoxide Sources in the Home CO is produced whenever a material burns. Homes with fuel-burning appliances or attached garages are more likely to have CO problems Common sources of CO in our homes include fuel-burning appliances and devices such as: Clothes dryers. Water heaters. Furnaces or boilers.
Which of the following pollutants is found in vehicle exhaust?
Pollutants produced by vehicle exhausts include carbon monoxide, hydrocarbons, nitrogen oxides, particles, volatile organic compounds and sulfur dioxide. Hydrocarbons and nitrogen oxides react with sunlight and warm temperatures to form ground-level ozone.
What is the source of carbon monoxide Mcq?
Carbon monoxide (CO)—a colorless, odorless, tasteless, and toxic air pollutant—is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood.
How is carbon monoxide produced by the vehicles?
Carbon monoxide results from incomplete combustion of fuel and is emitted di rectly from vehicle tailpipes. Incomplete combustion is most likely to occur at low air-to-fuel ratios in the engine.
What is the most common source of carbon monoxide quizlet?
The most common source of carbon monoxide pollution is vehicle exhaust. Since the implementation of the Clean Air Act, the concentrations of all major air pollutants have decreased.
What are vehicle pollutants?
The major pollutants released as vehicle/fuel emissions are, carbon monoxide (CO), nitrogen oxides (NOx), photochemical oxidants, air toxics, namely benzene (C6H6), aldehydes, 1,3 butadiene (C4H6), lead (Pb), particulate matter (PM), hydrocarbon (HC), oxides of sulphur (SO2) and polycyclic aromatic hydrocarbons (PAHs).
What does vehicle exhaust contain?
Motor vehicle exhaust emissions are known to contain carbon monoxide , nitrogen oxides , hydrocarbons , suspended particulate matter, and a small amount of sulfur dioxide .
Does car exhaust have carbon dioxide?
The majority of vehicle exhaust emissions are composed of carbon dioxide, nitrogen, water vapor, and oxygen in unconsumed air. Carbon monoxide, unburned fuel, nitrogen oxides, and particulate matter such as mercury are also present in vehicle exhaust emissions in smaller quantities.
Where is carbon monoxide mostly found?
CO is found in fumes produced any time you burn fuel in cars or trucks, small engines, stoves, lanterns, grills, fireplaces, gas ranges, or furnaces. CO can build up indoors and poison people and animals who breathe it.
Which fuel produces the most carbon monoxide?
When diesel fuel is burned incompletely or when overloaded and over-fueled (rich mixture), diesel engines will produce high concentrations of CO.
What is the main source of vehicular noise Mcq?
4. What is the main source of vehicular noise? Explanation: Most of the vehicular noise comes from the movement of the vehicle's tyres on the pavement and wind resistance.
