The fugitive emissions of volatile organic compounds (VOCs) from industrial processes are currently managed through in-person leak detection and repair (LDAR) efforts that are costly and occur periodically. These emissions are not rigorously accounted for in current emissions inv...

This is a public presentation on the potential effects of nutrients in smoke on downwind cyanobacteria blooms. Wildfire activity is increasing in the continental U.S. and can be linked to climate change effects, including rising temperatures and more frequent drought conditions. ...

The presentation reviews technologies using infrared and mass spectrometry. The lack of online techniques that are suitable for PFAS monitoring is shown to indicate that more research is needed in this area.

This presentation will be given at Air &amp; Waste Management Association's The Science of PFAS Conference. It provides a general overview of Other Test Method 50, a recently released method for analyzing volatile fluorinated compounds from sources. The method's applicability, sa...

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s in a wide array of consumer products. PFAS are persistent in the environment and bioaccumulate. Thermal treatment methods are currently applied to a variety of mater...

The use of air sensors continues to grow for a variety of air monitoring applications. However, the data quality still remains highly variable. In 2021, the U.S. EPA published reports outlining recommended testing protocols to evaluate the performance of fine particulate matter a...

Members of the Puente Jobos community in Puerto Rico shared with EPA concerns they have about particulate&nbsp;matter in their community and whether the location of the regulatory air monitoring site represents the community's&nbsp;exposure. EPA developed a research study design ...

Background:&nbsp;A fluorochemical facility near Fayetteville, North Carolina, emitted per- and polyfluoroalkyl ether acids (PFEAs), a subgroup of per- and polyfluoroalkyl substances (PFAS), to air. Objective:&nbsp;Analyze PFAS in private wells near the facility and in blood from ...

The rise of lower-cost air sensors allows higher spatial and temporal resolved measurements of air pollutants, supplementing traditional regulatory air monitoring. Supplemental data is especially important during wildfire episodes when first responders and nearby communities are ...

Fine particulate matter (PM2.5) resulting from wildland fire is a significant public health risk in the United States (U.S.). The existing stationary monitoring network and the tools used to alert the public of smoke conditions, such as the Air Quality Index or NowCast, are not o...

Reliable and comprehensive PFAS and PFAS-related emission measurement methods are needed for multiple purposes with some in use. Efficacy of combustion and non-combustion applications is important for all media and waste types with encouraging results and laboratory tests continu...

&nbsp; &nbsp; &nbsp; &nbsp; Research Ecologist Bob McKane with ORD-CPHEA-PESD will present a webinar on 5/15/2024 for EPA&rsquo;s Tools and Resources series on &ldquo;Prescribed Burning and Smoke Management Planning Tools &ndash; Flint Hills Case Study.&rdquo; This public webinar...

This presentation on ORD's Wildland Fire Smoke Research is part of a session titled &quot;Tackling the Climate Crisis: Highlighting EPA's Multi-pronged approach to Climate Change and Health&quot; at the 1st Annual CAFE Climate and Health Conference. This presentation will highlig...

Benthic diatoms are highly responsive to changes in environmental conditions associated with human activities. Their changes in assemblage structure can be used to develop stressor-response relationships, metrics, and indices that can help identify effects of pollution and inform...

This presentation summarizes perspectives from the U.S. Environmental Protection Agency&rsquo;s 2023 Air Sensors Quality Assurance Workshop (https://www.epa.gov/air-sensor-toolbox/quality-assurance-air-sensors#QAworkshop). Air sensors can provide valuable non-regulatory and suppl...

In July 2023, the US Environmental Protection Agency (EPA) hosted a workshop bringing together experts to discuss air sensor quality assurance (QA). This workshop focused on particulate matter (PM) sensors, fenceline and near-source community volatile organic compound (VOC) senso...

Background: Air pollution risk assessments do not generally quantify health impacts using multipollutant risk estimates, but instead use results from single-pollutant or copollutant models. Multipollutant epidemiological models account for pollutant interactions and joint effects...

Globally, billions of people burn fuels indoors for cooking and heating, which contributes to millions of chronic illnesses and premature deaths annually. Additionally, residential burning contributes significantly to black carbon emissions, which have the highest global warming ...

Data visualization tools that are quick and easy to use, require no coding skills, and can be used with any type of sensor are in high demand. &nbsp;In addition to visualizing their own data, users often wish to compare the data they collect with other nearby data sources such as...

The rapid proliferation of solar energy adoption presents a substantial environmental challenge concerning end-of-life solar panels. A primary issue involves the presence of hazardous materials like cadmium and lead in these panels [2]. Proper handling and disposal of these toxic...

Residential wood and pellet stoves produce smoke that contains multiple pollutants such as particulate matter (PM), volatile organic compounds (VOCs), and a plethora of other hazardous air pollutants (HAPs) that can contribute to poor air quality. VOCs from residential wood combu...

Communities located in near-road environments experience elevated levels of traffic-related air pollution. Near-road air pollution is a major public health concern, and an environmental justice issue. Roadside green infrastructure such as trees, hedges, and bushes may help reduce...
