EPA has conducted numous laboratory studies to evaluate cleaning, disinfection, air cleaning, and other approaches for reducing exposure to SARS-CoV-2. This presentation will summarize those research efforts and the high-level findings.

Homeland Security Research program overview and emerging challenge research projects. Advance EPA’s capabilities and those of our state, tribal, and local partners to respond to and recover from wide-area contamination incidents Improve the ability of water utilities to prevent, ...

As more workplaces, schools, and other mass gathering areas begin to reopen, they will need to think about the following three components of their operations during the COVID-19 pandemic: best cleaning approaches for common areas, monitoring water quality and water management pla...

The presentation provided an overview of the EPA Office of research and development COVID-19 disinfection research. This research is addressing the efficacy of antimicrobial coatings, disinfectant application, pesticide devices (e.g., UV-C) and aerosol treatment technologies. The...

The objective of this project is to evaluate antimicrobial products as long-lasting antimicrobials in laboratory testing &ndash; assessing their efficacy at reducing infectious virus recovery from surfaces that have been coated with the products. The evaluation will include asses...

This study extends laboratory findings to a field‐level evaluation using commercial off‐the‐shelf (COTS) humidifiers and 3% liquid hydrogen peroxide vapor.

The boiler exit flue gas of a municipal waste combustor was sampled to evaluate an on-line monitoring system for chlorobenzene congeners as indicators of polychlorinated dibenzodioxin and dibenzofuran (PCDD/PCDF) concentrations. Continuous measurements of chlorobenzene congeners ...

The effect of the injection of brominated powdered activated carbon (Br-PAC) on the emission of brominated and chlorinated dioxins and furans in coal combustion flue gas has been evaluated. The tests were performed at two U.S. Department of Energy (DOE) demonstration sites where ...

The effect of sulfur dioxide (SO2) on formation of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) has been studied in an entrained-flow reactor under simulated waste combustion conditions. A chlorination model based on conditional probability ...

The paper discusses results of an investigation on the importance of solid- and gas-phase carbon precursors for the formation of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs/Fs) during sooting combustion. Experiments were performed in an entrained flow reactor (EFR)...

Combustion experiments in a laboratory-scale fixed bed reactor were performed to determine the role of temperature and time in PCDD/F formation allowing a global kinetic expression to be written for PCDD/F formation due to soot oxidation in fly ash deposits. Rate constants were c...

Time-resolved evaluations of combustor performance have shown that concentrations of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) and related pollutants undergo significant changes as a response to upset combustion conditions. During and after tr...
