A combustion model, originally developed to simulate the destruction of chemical warfare agents, was modified include C1-C3 fluorinated organic reactions and kinetics compiled by National Institute Standards Technology (NIST). simplified plug flow reactor version this model used predict efficiency (DE) formation products incomplete (PICs) for three C1 C2 per- poly-fluorinated alkyl substances (PFAS) (CF4, CHF3, C2F6) compare predicted values Fourier Transform Infrared spectroscopy...
The destruction of per- and polyfluoroalkyl substances (PFAS) is critical to ensure effective remediation PFAS contaminated matrices. hazardous chemicals within incinerators other thermal treatment processes has historically been determined by calculating the efficiency (DE) or removal (DRE). While high DEs, >99.99%, are deemed acceptable for most compounds, many can be converted at low temperatures resulting in DEs without full mineralization potential release remaining fluorocarbon...
This paper discusses the work and results to date leading demonstration of corona destruction process at pilot scale. The research effort in volatile organic compounds (VOCs) air toxics has shown significant promise for providing a valuable contribution critical U.S. Environmental Protection Agency national goals reducing health effects associated with exposures hazardous pollutants. technology could be especially useful future years helping industry meet residual risk requirements Clean Air...
This paper presents a summary of fireplace particle size and organic speciation data gathered to date in an ongoing project. Tests are being conducted residential wood combustion (RWC) laboratory on three factory-built fireplaces. RWC smoke particles <10 μm (PM10) consist primarily mixture compounds that have condensed into droplets; therefore, the distribution total mass influenced by temperature sample during its collection. During series 1 tests (15 tests), dilution tunnel used cool...
Ethylene oxide (EtO) is a hazardous air pollutant that can be emitted from variety of difficult to measure industrial sources, such as fugitive leaks, wastewater handling, and episodic releases. Emerging next generation emission measurement (NGEM) approaches capable time-resolved, low parts per billion by volume (ppbv) method detection limits (MDLs) help facilities understand reduce EtO other emissions these sources yielding range environmental public health benefits. In October 2021, first...
Gaseous and particulate emissions from the combustion of coal have been associated with adverse effects on human environmental health, for that reason subject to regulation by federal state governments. Recent regulations United States Environmental Protection Agency further restricted acid gases electricity generating facilities other industrial facilities, upcoming deadlines are forcing industry consider both pre- post-combustion controls maintain compliance. As a result these recent...

Bacillus anthracis (B. anthracis) spores were released through the U.S. mail system in 2001, highlighting need to develop efficacious methods of decontaminating and disposing materials contaminated with biological agents. Incineration building decontamination residue is a disposal option for such material, although complete inactivation bacterial via this technique not certainty. Tests revealed that under some circumstances, Geobacillus stearothermophilus (G. stearothermophilus; surrogate B....
This paper summarizes the key characteristics of United States Environmental Protection Agency's (U.S. EPA's) Mercury Measurement Toolkit and experiences using it to develop emission factors for coal-fired power plants in China, Russia, South Africa. The U.S. EPA developed tested a portable mercury sampling analytical laboratory (the EPA's Toolkit). is designed efficiently economically determine speciated emissions on site at facilities. EPA, working with Nations Environment Programme (UNEP)...
Abstract Sampling and analytical procedures used to determine total mercury content in crude oils were examined. Three methods compared with respect accuracy, precision, detection limit. The combustion method (U.S. EPA 7473 hybrid) a commercial extraction (non-standard) found adequate provide good combination of sensitivity while instrumental neutron activation analysis was suffer from interferences elements other than (Ni, Se) that are typically oil. Aliquot removal processing steps be...
This paper describes the development of a new mobile laboratory for determination fine particle and gaseous emissions from class 8 diesel tractor—trailer research vehicle. The [Diesel Emissions Aerosol Laboratory (DEAL)] incorporates plumesampling capabilities which were based on detailed flow field analysis using combination computational fluid dynamics modelling, visualization smoke, streamers, oil spots, tracer gas measurements results are described in paper. DEAL unique ability to...
There is a growing awareness of the health impacts ethylene oxide (EtO) and its role as carcinogenic mutagenic air contaminant concern. Given need to better understand EtO emissions associated effects, it imperative overcome significant challenges with measurement in complex matrices, such combustion emissions. This work focused on addressing these by evaluating utility widely used canister-based ambient approaches, EPA Methods TO-15 TO-15A, investigate presence heavy-duty diesel vehicle...
