This category includes hazardous air pollutants, as listed in Section 112 of the U.S. Clean Air Act (1970) and Clean Air Act (1990). The list can be found on Wikipedia at National Emissions Standards for Hazardous Air Pollutants , and on EPA at [1] .
There are many different sources of air pollution. Some air pollutants (such as nitrogen oxides) originate mainly from human activities, [39] while some (notably radon gas) come mostly from natural sources. [40] However, many air pollutants (including dust and sulfur dioxide) come from a mixture of natural and human sources. [41]
The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
These sections require the EPA "(1) to list widespread air pollutants that reasonably may be expected to endanger public health or welfare; (2) to issue air quality criteria for them that assess the latest available scientific information on nature and effects of ambient exposure to them; (3) to set primary NAAQS to protect human health with ...
All sorts of things can affect the air quality in your home, from burning candles and smoke and gas from cooking to specific types of air fresheners. Some of the worst pollutants include packaging ...
Since the EPA first started regulating clean air in the 1970s, emissions of the most common air pollutants have dropped by almost 80%. But around Houston, there's still a long way to go. Each year ...
The National Emissions Standards for Hazardous Air Pollutants (NESHAPs) govern how much of 187 toxic air pollutants are allowed to be emitted from industrial facilities and other sources. [8] Under the CAA, hazardous air pollutants (HAPs, or air toxics) are air pollutants other than those for which NAAQS exist, which threaten human health and ...
In 2017, the biggest pollutants included carbon dioxide, nitrogen oxide, hydrocarbons, lead, and particulate matter according to Theilmann in the U.S. Clean Air Act. [5] These pollutants harm the environment as well as the citizens living in these areas. The pollutants contribute to climate change and can result in acid rain. Citizens living in ...
