The United States Environmental Protection Agency (US EPA) has established National Ambient Air Quality Standards (NAAQS) for the six most common air pollutants as:
What is air pollution?
The introduction of harmful agents into the atmosphere is known as air pollution. The toxic agents are known as pollutants. These pollutants are derived from natural and human activities, and they can be chemical or biological.
What is Outdoor and Indoor pollution?
Air pollution in the outside environment is called outdoor pollution. The examples of outdoor pollution are as follows:
What are the Air Quality Standards set up by NAAQS?
Environment Protection Agency (EPA) has determined the air quality index (AQI) to know the air quality you inhale. The table given below will show how the air quality index looks like.
How can I individually reduce air pollution?
You can always try your level best to minimise air pollution. The following are the methods to reduce air pollution at an individual level.
How can the local authorities improve the air quality of your region?
You can always observe the changes happening in your surrounding nature. If you experience bad air quality or any activities producing air pollution, you can always concern relevant local authorities or the mayor.
What are the primary cause of air pollution and its effect on the environment?
The burning of fossil fuels is the primary cause of air pollution. Combustion of fossil fuel is needed in the transportation sector, energy generation, and cooking activities. Such activities release a tremendous amount of carbon monoxide and other toxic pollutants into the atmosphere. These contaminants cause harm to human health, hampers flora and fauna growth, and create food insecurity.
What are the criteria pollutants?
Environmental Protection Agency set national standards for six common air pollutants, known as criteria pollutants: Ground-level ozone. Particulate matter. Carbon monoxide.
Why is the downward trend of criteria pollutant control measures?
This downward trend is a result of criteria pollutant control measures that have achieved air quality improvements despite regional growth in the local economy, population, and traffic.

What are the most common pollutants in the air?
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”). The presence of these pollutants in ambient air is generally due to numerous diverse and widespread sources of emissions. The primary NAAQS are set to protect public health. EPA also sets secondary NAAQS to protect public welfare from adverse effects of criteria pollutants, including protection against visibility impairment, or damage to animals, crops, vegetation, or buildings.
Why are air quality standards important?
Some of the air quality standards are designed to protect the public from adverse health effects that can occur after being exposed for a short time, such as hours to days. Other standards are designed to protect people from adverse health effects that are associated with long-term

Children, older adults, individuals with preexisting heart and lung disease (including asthma), and persons with lower socioeconomic status are considered to be among the groups most at risk for effects associated with PM exposures.
Why is it difficult to distinguish between prenatal and early childhood exposure?
However, it is often difficult to distinguish the effects of prenatal and early childhood exposure because exposure to air pollutants is often very similar during both time periods.
What are the pollutants in the air?
The pollutants are particulate matter, ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide and lead. EPA calls these pollutants “criteria” air pollutants because it sets NAAQS for them based on criteria: the latest scientific information regarding their effects on health or welfare.
Who is most likely to be affected by particle pollution?
People with heart or lung diseases, children, and older adults are the most likely to be affected by particle pollution exposure.
What is the Clean Air Act?
The Clean Air Act contains key provisions to control common pollutants which, at the time of the enactment of the law in 1970, formed dense, visible smog in many of the nation’s cities and industrial centers. To protect public health and welfare nationwide, the CAA requires EPA to establish National Ambient Air Quality Standards (NAAQS) ...
What are primary standards?
Primary standards provide public health protection, including protecting the health of sensitive populations such as asthmatics, children and the elderly. Secondary standards provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation and buildings.
How much has lead decreased in the air?
As a result of EPA's regulatory efforts including the removal of lead from motor vehicle gasoline, levels of lead in the air nationally have decreased by 98% between 1980 and 2014.
What is attainment status?
Attainment status is a federal designation of whether the air quality in an entire state, or an area therein, meets the NAAQS. If an area is designated as nonattainment, states must develop a SIP that details the path to attainment and maintenance of NAAQS. In the past, portions of the state have been designated nonattainment for the 1971 CO standard, the 1979 1-hour and 1997 8-hour ozone standards, and the 2010 SO 2 standard. New Hampshire’s air quality currently meets all federal standards. Certain Northeast states, including NH, are included in the Ozone Transport Region (OTR), and must submit SIPs for the pollutants that form ozone regardless of attainment status.
