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...

Wildfires have increased in frequency and area burned, trends expected to continue with climate change. Among other effects, fires release pollutants into the atmosphere, representing a risk to human health and downwind terrestrial and aquatic ecosystems. While human health risks...

Invited Question and Answer article for Nature Cardiovascular Research on Particulate Matter.Recent air-quality alerts in major cities due to the wildfires in Canada, Hawaii and Greece have put fine particulate matter (PM) pollution and consequent health issues into the spotlight...

Atmospheric nitrate is a key atmosphere component with implications for air quality, nutrient deposition, and climate.  However, accurately representing atmospheric nitrate concentrations within atmospheric chemistry models is a persistent challenge.  A contributing fac...

The US EPA has developed a set of annual North American anthropogenic and fire emissions data for criteria air pollutants across 18 broad source catagories for 2002 through 2017.  The sixteen new annual emissions inventories were developed using consistent input data and met...

Accurate fire emissions inventories are crucial to predict the impacts of wildland fires on air quality and atmospheric composition. Two traditional approaches are widely used to calculate fire emissions: a satellite-based top-down approach and a fuels-based bottom-up approach. H...

In recent years, the emission of particles and gaseous pollutants from 3D printing has attracted much attention due to potential health risks. This study investigated the generation of environmentally persistent free radicals (EPFRs, organic free radicals stabilized on or inside ...

Journal article submitted to EcoHealth - (Abstract) - Lyme disease (LD) is the most common vector-borne disease in the United States (U.S.). This paper assesses how climate change may influence LD incidence in the eastern and upper midwestern U.S., and the associated economic bur...

Evidence suggests that clothing can influence human exposure to semi-volatile organic compounds (SVOCs) through transdermal uptake and inhalation. Accordingly, a computational modeling framework (ABICAM) was expanded and applied to assess the dynamics of human exposure to gas-pha...

Partitioning of per- and polyfluoroalkyl substances (PFAS) to indoor materials, including clothing, may prolong the residence time of PFAS indoors and contribute to exposure. During the Indoor PFAS Assessment (IPA) Campaign, we measured concentrations of nine neutral PFAS in air ...

Atmospheric nitrogen (N) and sulfur (S) deposition can significantly affect forest biodiversity and production by altering the growth and survival of trees. Three decades of air quality regulations in the United States have led to large reductions in oxides of N (44–81%) an...

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...

During April 30–August 4, 2023, smoke originating from wildfires in Canada affected most of the contiguous United States. CDC used National Syndromic Surveillance Program data to assess numbers and percentages of asthma-associated emergency department (ED) visits on days wi...

Background: While benefits of greenness to health have been reported, findings specific to child respiratory health are inconsistent. Methods: We utilized a prospective birth cohort followed from birth to age 7 years (n = 617). Residential surrounding greenness was quan...

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...

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...

Freshwater ecosystems, including lakes, streams, and wetlands, are responsive to climate change and other natural and anthropogenic stresses. These ecosystems are generally hydrologically connected with one another and with the landscapes around them, integrating changes that occ...

Background Ambient fine particulate matter (PM2.5) contributes to global morbidity and mortality. One way to understand the health effects of PM2.5 is by examining its impact on performed hospital procedures, particularly among those with existing chronic disease. However, s...

There is growing interest in understanding how maternal diet might affect the sensitivity of offspring to environmental exposures. Previous studies demonstrated that adult rat offspring (approximately 6-months-old) from dams given a high-fat diet (HFD) prior to, during, and after...

Objectives: California plans to substantially increase the use of prescribed fire to reduce risk of catastrophic wildfires. Although for a beneficial purpose, prescribed fire smoke may still pose a health concern, especially among sensitive populations. We sought to understand co...

Differentiated primary human bronchial epithelial cell (dpHBEC) cultures grown under air-liquid interface (ALI) conditions exhibit key features of the human respiratory tract and are thus critical for respiratory research as well as efficacy and toxicity testing of...

Ecosystem services (ES) are defined as the outputs of ecological processes that contribute to human welfare or have the potential to do so in the future, and include the production of food and drinking water, purification of air and water, pollination, and nutrient cycling. The n...

Per- and polyfluoroalkyl substances (PFAS) are used in various industrial products; however, they pose serious health risks. In this study, soil, soil gas, and groundwater samples were collected at a PFAS manufacturing facility in New Jersey, USA, to determine the presence and di...

Solutions-driven research is a transdisciplinary approach that incorporates diverse forms of expertise to identify solutions to stakeholder-identified environmental problems. This qualitative evaluation of early solutions-driven research projects provides transferable recommendat...

Aqueous film-forming foams (AFFFs) are used in firefighting applications, and often contain per- and polyfluoroalkyl substances (PFAS), which can detrimentally impact environmental and biological health. Incineration is a potential disposal method for AFFFs, which may produce sec...
