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...

Background: Co-exposure to air pollution and neighborhood disadvantage may influence cognitive decline. We tested these associations in the context of dementia risk. Methods: We leveraged a cohort of community dwelling adults &ge;65 years (n=5,112) enrolled from 2011 to 2018 in ...

Ozone (O3) and nitrogen dioxide (NO2) are common air pollutants and highly reactive gases that can induce airway irritation and inflammation. O3 exposure is associated with COPD, type II diabetes, cardiovascular disease, NO2 exposure is associated with asthma and COPD exacerbatio...

Due to some Per and Polyfluoroalkyl substances (PFAS) having both hydrophilic and hydrophobic components on the same structure, they are often found at the interface between air and water. This behavior results in PFAS concentrating in the surface microlayer. When surface water i...

With the declining tailpipe emissions from the US and worldwide motor vehicle fleet, impacts of tire and brake wear are an increasingly important area of interest.&nbsp; Recent research has shown the compound 6PPD used in tires as an anti-degradation chemical reacts with ozone to...

The design of emission abatement measures to effectivly reduce high ground-level ozone (O3) concentrations in urban areas is very complex. In addition to the strongly non-linear chemistry of this secondary pollutant, precursors can be released by a variety of sources in different...

Residents and local agencies in smoke impacted areas often use air sensors to provide more localized air quality data. In 2020, air sensor measurements were added to the AirNow Fire and Smoke map. Alongside permanent and temporary smoke monitor measurements, PurpleAir sensor meas...

Wildland fires have increased in magnitude over the past several decades, burning millions of acres of natural landscape each year. Over this same time, the number of communities that are adjacent to or intermixed among wildlands has increased. This intersection has led to an inc...

Developing SEEA accounts requires collecting environmental emissions or resource use data and associating it with sectors that supply or use these resources, making it parallel to standardized national economic accounts.There are other fields of applied science or environmental a...

The content covers the validation of the NASA TEMPO mission with direct sun and multi-axis retrievals of NO2 and formaldehyde trace gas vertical column products from the Pandonia Global Network. The slides present nuances in the strengths and weakness of Pandonia Global Network d...

The Clean Air Act requires the Environmental Protection Agency to set National Ambient Air Quality Standard (NAAQS) to protect the public health and welfare against exposures to the &ldquo;criteria&rdquo; air pollutants. EPA has identified six criteria pollutants, including ozone...

Air quality regulations decreased nitrogen (N) and sulfur deposition across the conterminous United States (CONUS) during the last several decades. But it is unclear if declining deposition has also altered stream N at large scales. We compared watershed N inputs with N chemistry...

If a water body in the United States is not as healthy as we&rsquo;ve decided it should be, the most likely cause is nutrient pollution &lt;span style='mso-element:field-begin'&gt;&lt;span style='mso-spacerun:yes'&gt;&nbsp;ADDIN EN.CITE &lt;EndNote&gt;&lt;Cite&gt;&lt;Author&gt;US...

As the development and use of air sensors continues to expand, understanding the performance of sensors remains a critical need given the variability in sensor data quality. To help support consumers and developers of air sensor technologies, the U.S. Environmental Protection Age...

EPA&rsquo;s Report on the Environment (ROE) brings together the most reliable and readily available indicators to create a comprehensive view of the nation&rsquo;s environmental and human health status and trends. The indicators provide an objective basis for Agency decision maki...

This presentation will be given at the 45th Conference for Stationary Source Sampling and Analysis for Air Pollutants. It will be included in the &quot;EPA Highlights&quot; session where EPA staff will provide a summary of the past year's key developments in air emissions measure...

The etiology of bladder cancer among never smokers without occupational or environmental exposure to established urothelial carcinogens remains unclear. Urinary mutagenicity is an integrative measure that reflects recent exposure to genotoxic agents. Here, we investigated its pot...

Unmanned aircraft systems (UAS, or drones) have been used to characterize emissions from prescribed forest and grassland fires.&nbsp;

&ldquo;Ecosystem services&rdquo; are the benefits ecosystems provide to people. These benefits include providing food, clean air, clean water, recreation, and many other services that provide explicit or intrinsic values to people and communities. Investments in Chesapeake Bay re...

Quantifying the influence of environmental factors on species distributions can elucidate their ecological requirements and potential response to anthropogenic disturbance. Single species distribution models are commonly used to quantify taxon-environment relationships but do not...

For decades, researchers have sought to document injustices, highlight activism, and identify pathways in moving toward environmental justice (EJ). EJ research regarding water has been predominantly focused on drinking water. This project sought to identify and analyze the breadt...
