Detection of airborne Coccidioides spores using drones in the Carrizo Plain, California: A pilot study
(PRESENTATION) [Presented : Nov 17, 2023]
Background and Objectives: Coccidioidomycosis is an emerging fungal infection caused by inhalation of airborne spores of the Coccidioides genus. While Coccidioides immitis has been detected in soils across California, few studies have detected the spores in air, limiting understa...
Patterns of microparticles in blank samples: A study to inform best practices for microplastic analysis
(JOURNAL) [Published : Aug 01, 2023]
Quality assurance and quality control (QA/QC) techniques are critical to analytical chemistry, and thus the analysis of microplastics. Procedural blanks are a key component of QA/QC for quantifying and characterizing background contamination. Although procedural blanks are becomi...

Impact of do-it-yourself air cleaner design on the reduction of simulated wildfire smoke in a controlled chamber environment
(JOURNAL) [Published : Nov 25, 2022]
ORD researchers will summarize and discuss laboratory study results evaluating the particulate matter removal effectiveness of do-it-yourself (DIY) air cleaners. These air cleaners are commonly used to filter smoke particles during wildland fires and are made by attaching an air ...
Results for Aerosol Treatment Technology Evaluation with the Knorr 3-Stage Air Filtration and Purification System
(SUMMARY) [Published : Aug 02, 2022]
This website update provides a summary of efficacy testing with the Knorr 3-Stage Air Filtration and Purification System in a large aerosol test chamber with a recirculating HVAC system. The unit's efficacy was evaluated against aerosolized MS2 (a bacteriophage).

Creating Clean Air Spaces During Wildland Fire Smoke Episodes: Web Summit Summary
(JOURNAL) [Published : Feb 15, 2021]
Effective strategies to reduce indoor air pollutant concentrations during wildfire smoke events are critically needed. Worldwide, communities in areas prone to wildfires may suffer from annual smoke exposure events lasting from days to weeks. In addition, there are many areas of ...
Evaluating Aerosol Treatment Methods for Reducing the Risk of Exposure to Airborne Pathogens
(PRESENTATION) [Presented : Nov 05, 2021]
The COVID-19 pandemic has highlighted the role that airborne transmission can play in the spread of disease. Consequently, there has been an increasing focus on technologies that claim to reduce or eliminate aerosolized pathogens in indoor occupied spaces. There are many differen...

Field Study Summary: PM2.5 Measurements Inside and Outside of Buildings in Missoula, MT During Summer 2019
(PRESENTATION) [Presented : Feb 20, 2020]
This presentation describes a field study to observe indoor and outdoor PM2.5 concentrations during wildfire season, implemented through a partnership between EPA ORD, Missoula City-County Health Department, and University of Montana, with some additional field logistics support ...
Impacts of wildfire smoke on indoor air quality and methods to mitigate exposure: A field and lab study
(PRESENTATION) [Presented : Oct 28, 2020]
Wildland fire smoke is a global public health issue. Many communities are exposed to smoke from fires for days, weeks, or even months, which poses the risk of adverse health effects due to sustained exposure to high concentrations of fine particles (PM2.5) and other pollutants. A...
Wildfire Smoke Episodes: Working with Local and Tribal Partners to Enhance Understanding of Indoor Air Exposures
(PRESENTATION) [Presented : Nov 19, 2020]
Background: Wildland fire smoke is a global public health issue. Many communities are exposed to smoke from wildland fires, both wild and controlled burns, for days, weeks, or even months in a given year. With that smoke comes high concentrations of fine particles (PM2.5) and oth...

How could all that stuff be in my blank!? (GSRS)
(PRESENTATION) [Presented : Sep 24, 2019]
Awareness of microplastics in our environment, and the commitment of research to understand their fate and effects is rapidly increasing. Accurate measurement of microplastics in environmental matrices is key to understanding sources, transport, sinks, and ultimately ecological ...
PROTOCOL FOR DETECTION OF FRANCISELLA TULARENSIS IN ENVIRONMENTAL SAMPLES DURING THE REMEDIATION PHASE OF A TULAREMIA INCIDENT
(PUBLISHED REPORT) [Published : Sep 01, 2019]
Francisella tularensis, the bacterium that causes Tularemia infection, is a high-priority bioterrorism agent. There is no step‐by‐step analytical protocol for detection of Francisella tularensis in environmental samples that can be used by the EPA’s Environmental Response Laborat...

Air Change Rates and Interzonal Flows in Residences, and the Need for Multi-Zone Models for Exposure and Health Analysis
(JOURNAL) [Published : Dec 12, 2012]
Air change rates (ACRs) and interzonal flows are key determinants of indoor air quality (IAQ) and building energy use. This paper characterizes ACRs and interzonal flows in 126 houses, and evaluates effects of these parameters on IAQ. ACRs measured using weeklong tracer measureme...
Characterization of Iron Welding Fumes for Potential Beneficial Use in Environmental Remediation
(PRESENTATION) [Presented : Jul 31, 2012]
Research regarding nanoparticles generated as waste byproducts during industrial practices has received little attention in the environmental science and engineering literature. The physical and chemical characteristics and properties need to be considered when evaluating potent...
