What are the two major sources of air pollution?
What are the two major sources of air pollution?
mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.
What are the major sources of primary air pollutants quizlet?
The five primary air pollutants include carbon monoxide, nitrogen oxides, particulate matter, sulfur oxides, and volatile organic compounds. The sources for all five of these pollutants include electricity production, industry, and transportation.
Which are the 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.
What are the 5 primary pollutants?
Types of primary pollutants include:
- Nitrogen oxides (NOx)
- Carbon monoxide (CO)
- Volatile organic compounds (VOCs)
- Sulfur oxides (SOx)
- Particulate matter (PM)
- Mercury.
- and more.
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 are secondary pollutants give examples?
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 three sources of particulate matter?
About the data Natural sources of PM include sea salt, dust (airborne soil, also called crustal material), secondary sulphate, pollen, black carbon from wild fires, and volcanic ash.
What are the types of particulates?
Particulate matter is separated into three main groupings: coarse particles (PM10), fine particles (PM2. 5), and ultrafine particles (PM0. 1). These particle sizes, in general, differ in origin and health effects.
Which one is not a particulate?
So, the correct answer is ‘Nitric oxide’
What is a good particulate matter reading?
On a very clear and non-hazy day, the PM2.5 concentration can be as low as 5 μg/m3 or below. The 24-hour concentration of PM2.5 is considered unhealthy when it rises above 35.4 μg/m3.
What air pollutants scare lungs?
Asbestosis—asbestos fibers cut and scar the lungs, causing difficulty in breathing.
What are the three main long term effects of air pollution?
Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people’s nerves, brain, kidneys, liver, and other organs.
What pollutants are put directly into the air by humans?
Criteria Air PollutantsThese pollutants are particulate matter, photochemical oxidants (including ozone), carbon monoxide, sulfur oxides, nitrogen oxides and lead.
Is Pan a secondary air pollutant?
Peroxyacetyl nitrate (PAN) and ozone are the two important secondary photochemical air pollutants found in the urban at- mosphere (1-3). Of the two, PAN is the more useful indicator of photochemical reactions in polluted air as, unlike ozone, it appears to have no large natural source (2-7).
