The 1990 Clean Air Act Amendment (CAAA) empowered the U.S. Environmental Protection Agency (EPA) to set emission standards for a number of potentially hazardous air pollutants (HAPS) generated by a variety of specific combustion sources. Eleven elements (or compounds of these elements) present in coal are among the 189 pollutants identified as air toxics by the CAAA legislation. Mercury is incl...

Industrial, commercial, and institutional (ICI) boilers are one of the major sources of hazardous air pollutants (HAP), including mercury (Hg). Coal-fired electric power plants constitute the largest point source of anthropogenic Hg in the United States. The primary objective of this paper was to address the mercury side of the boiler maximum achievable control technology (MACT) of the national...

In a bid to provide better protection for children's health, U.S. Senators Barbara Boxer (D-California) and Frank Lautenberg (D-New Jersey) introduced the Children's Environmental Protection Act (CEPA), on 24 May 1999. CEPA is an amendment to the Toxic Substances Control Act of 1976 and seeks to protect children from exposures to hazardous substances such as toxic air pollutants and pesticides ...

biofiltration method is one of the most commonly used and most effective methods to removepollutants from the exhaust gas flow from different industries. one of the most important categories of airpollutants is hap (hazardous air pollutants). this study assesses the ability of biofiltration method toremove and treat hap dea (diethanolamine) from a gas stream through a laboratory-scale biofilter...

3. Applicable Pollutants: Particulate Matter (PM), including particulate matter less than or equal to 10 micrometers (μm) in aerodynamic diameter (PM10), particulate matter less than or equal to 2.5 μm in aerodynamic diameter (PM2.5), and hazardous air pollutants (HAPs) that are in particulate form, such as most metals (except mercury is the notable exception, as a significant portion of emissi...
