EPA has established national ambient air quality standards (NAAQS) for six of the most common air pollutants— carbon monoxide, lead, ground-level ozone, particulate matter, nitrogen dioxide, and sulfur dioxide —known as “criteria” air pollutants (or simply “criteria pollutants”).
What pollutants does the EPA track?
EPA has established national ambient air quality standards (NAAQS) for six of the most common air pollutants— carbon monoxide, lead, ground-level ozone, particulate matter, nitrogen dioxide, and sulfur dioxide —known as “criteria” air pollutants (or simply “criteria pollutants”).
Which of the following pollutants is not closely tracked by the US EPA?
Which of the following damaging pollutants is NOT closely tracked by the U.S. EPA? While mercury is a neurotoxin, it is not produced in quantity by many sources, so the EPA does not track it nationally (it is not a criteria air pollutant).
What are the six major pollutants according to EPA of USA?
These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
Which of the following compounds is classified by the EPA as a pollutant?
EPA calls this set of principal air pollutants, criteria pollutants. The criteria pollutants are carbon monoxide (CO), lead (Pb), nitrogen dioxide(NO 2 ), ozone (O 3 ), particulate matter (PM), and sulfur dioxide (SO 2 ) .
What are three currently monitored major air pollutants by the EPA?
The Clean Air Act requires EPA to set National Ambient Air Quality Standards (NAAQS) NAAQS are currently set for carbon monoxide, lead, ground-level ozone, nitrogen dioxide, particulate matter, and sulfur dioxide .
What are the most common air pollutants answers?
- Particulate matter (PM10 and PM2. ...
- Ozone (O3)
- Nitrogen dioxide (NO2)
- Carbon monoxide (CO)
- Sulphur dioxide (SO2)
What are the six major outdoor air pollutants regulated by the EPA quizlet?
EPA has set air quality standards for six common “criteria pollutants”: particulate matter (also known as particle pollution), ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead . States are required to adopt enforceable plans to achieve and maintain air quality meeting the air quality standards.
How many air pollutants are routinely monitored by the EPA to determine air quality?
EPA identified six criteria pollutants: particulate matter (PM), ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxide (NO), and lead (Pb) and set the standards as a function of the characteristics and their potential health and welfare effects.
What are the 7 criteria air pollutants?
The criteria air pollutants include particle pollution, ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead . These pollutants can harm your health and the environment, and cause property damage.
Which two pollutants are the greatest threat to human health?
Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country.
Which air pollutant is not regulated by the EPA?
Currently, there are no EPA regulations or standards for airborne mold contaminants . Learn more about mold on our Mold and Moisture site.
What are the air pollutants and their sources?
| pollutant common sources | carbon monoxide (CO) automobile emissions, fires, industrial processes | nitrogen oxides (NO and NO 2 ) automobile emissions, electricity generation, industrial processes | sulfur dioxide (SO 2 ) electricity generation, fossil-fuel combustion, industrial processes, automobile emissions |

What are the six levels of air quality?
An AQI value of 100 generally corresponds to the level of the short-term National Ambient Air Quality Standard. The EPA has set National Ambient Air Quality Standards for six criteria pollutants: sulfur dioxide (S02), particulates (PM2. 5/PM10), nitrogen oxides (NOx), carbon monoxide (CO), ozone (O3), and lead (Pb) .
What is the most toxic air pollutant?
The more dangerous air pollutants are: Sulphur Dioxide – high concentrations can result in breathing impairment for asthmatics that are active outdoors.
What are the 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; carbon monoxide; sulfur oxides; nitrogen oxides; and lead .
