2025年2月11日 · Hazardous air pollutants are those known to cause cancer and other serious health impacts. The Clean Air Act requires the EPA to regulate hazardous air pollutants, also known as air toxics, from categories of industrial facilities in two phases .

In the 2012 final MATS, the EPA established standards to limit emissions of mercury; acid gas hazardous air pollutants (HAP) such as hydrogen chloride (HCl) and hydrogen fluoride; non-mercury HAP metals such as nickel, lead, and chromium; and organic HAP such as formaldehyde and dioxins/furans from coal- and oil-fired power plants.

2024年4月24日 · mercury and non-mercury metal hazardous air pollutants (HAPs), such as nickel, arsenic, and lead. • MATS pairs a stronger filterable particulate matter (fPM) standard, as a surrogate for non-mercury HAP metals, with a requirement to use continuous emissions monitoring (CEMs) at the stack. The standard and monitoring

2024年5月15日 · Ohio Lumex is currently developing a sorbent trap method for continuous monitoring of metal Hazardous Air Pollutants (HAP) emissions, with support from the U.S. Environmental Protection Agency (EPA) Small Business Innovation and …

Based on its latest assessment of available control technologies, EPA is proposing to further limit the emission of non-mercury HAP metals from existing coal-fired power plants by significantly reducing the emission standard for filterable particulate matter (fPM), which is designed to control non-mercury HAP metals.

HAP metals mean those metals and their compounds (in particulate or volatile form) that are included on the list of hazardous air pollutants in section 112 of the Clean Air Act.

Hazardous air pollutants (HAPs) or air toxics are considered to cause serious health effects including cancer, damage to the immune system, as well as neurological, reproductive, developmental, respiratory and other health problems.

2025年1月5日 · Heavy metals (HMs) represent a persistent and significant threat to aquatic ecosystems. Hydroxyapatite (HAp) has emerged as a utilized material in the remediation of environmental HMs, owing to its exceptionally high porosity, expansive surface area, and the presence of three-dimensional ordered channels.
