What is the most dangerous air pollutant?
We see Radon as the most dangerous indoor air pollutant in the western world nowadays. This is because of several reasons: Radon is the number one cause of lung cancer among non-smokers.
What are the two main pollutants of air?
Criteria pollutants
| pollutant | common sources |
|---|---|
| carbon monoxide (CO) | automobile emissions, fires, industrial processes |
| nitrogen oxides (NO and NO2) | automobile emissions, electricity generation, industrial processes |
| sulfur dioxide (SO2) | electricity generation, fossil-fuel combustion, industrial processes, automobile emissions |
What are the major components of air pollution?
These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
What components of air pollution are most harmful to our health?
Furthermore, nitrogen oxide, sulfur dioxide, Volatile Organic Compounds (VOCs), dioxins, and polycyclic aromatic hydrocarbons (PAHs) are all considered air pollutants that are harmful to humans. Carbon monoxide can even provoke direct poisoning when breathed in at high levels.
What are the 3 most dangerous air pollutants?
Pollen.
Why is air pollution most dangerous?
Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Conditions such as asthma, heart disease, and lung disease can be made worse by exposure to air pollution. The length of exposure and amount and type of pollutants are also factors.
What are the two major pollutants that are most common in the atmosphere?
Known as criteria air pollutants, the six most common pollutants include ozone, carbon monoxide, sulfur dioxide, lead, nitrogen oxides, and particulate matter. Greenhouse gases are another form of hazardous air pollution.
What is the biggest air pollutant?

- Six Common Pollutants (EPA)
What are three types pollution?
The three major types of pollution are air pollution, water pollution, and land pollution. Sometimes, air pollution is visible. A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible.
Where is air pollution the worst?

What are the most common types of air pollution?
1 Smog and soot. These are the two most prevalent types of air pollution. 2 Hazardous air pollutants. A number of air pollutants pose severe health risks and can sometimes be fatal even in small amounts. 3 Greenhouse gases. 4 Pollen and mold.
Why are there six criteria pollutants in the air?
The EPA has identified six pollutants as “criteria” air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels.
What are the most dangerous threats to air quality?
The main threats to local air quality across the United States (as well as most everywhere else) remain smog and particulate pollution, which combined or acting alone trigger millions of hospital visits and health complications for citizens every year.
What are the six pollutants that the EPA regulates?
The EPA has identified six pollutants as “criteria” air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels.
