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...

Estimating population exposure to particulate matter during wildfires can be difficult because of insufficient monitoring data to capture the spatiotemporal variability of smoke plumes. Chemical transport models (CTMs) and satellite retrievals provide spatiotemporal data that may...

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...

Past work has shown that traffic patterns in the USA and resulting NOx emissions vary by day of week, with NOx emissions typically being higher on weekdays than weekends. This pattern of emissions leads to different levels of ozone on weekends versus weekdays and can be...

As a Nature-Based Solution, roadside green infrastructure (also known as roadside barriers) can potentially mitigate traffic-related air pollution by increasing dispersion and promoting pollutant deposition. For new and existing barriers, the vegetation’s physical and ecolo...

This paper focuses on the impact of solid barriers located upwind of a highway in reducing vehicle related concentrations that occur downwind of the roadway, compared to a highway without barriers. Measurements made in the United States Environmental Protection Agency’s met...

Mobile sources are responsible for a substantial controllable portion of the reactive organic carbon (ROC) emitted to the atmosphere, especially in urban environments of the United States. We update existing methods for calculating mobile source organic particle and vapor emissio...

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...

During the immediate, emergency phase of a response to a radiological dispersal device (RDD), an improvised nuclear device (IND), or accidental radiological release, emergency responders may be exposed to radioactivity due to inhalation and direct contact. It is important to mini...

Exposure to particulate matter (PM) air pollution is associated with an increased risk of adverse human health effects. As more attention is brought to bear on the problem of PM, traditional in vivo models struggle to keep up with the risk assessment challenges posed by the count...

Tracer flux ratio (TFR) methodology performed at 15 active oil and natural gas production sites in Ohio County, West Virginia sought to quantify downwind emissions on several days in April 2018. In coordination with a production company, sites were randomly selected depending on ...

Direct exposure to household fine particulate air pollution (HAP) associated with the inefficient combustion of fuels (wood, charcoal, coal, crop residues, kerosene, etc.) for cooking, space-heating, and lighting is estimated to result in 2.3 (1.6-3.1) million premature yearly de...

Transport of contaminants from roadways to the environment is well known, although studies of technologies for preventing and managing this appear infrequently in the literature. This paper reviews technologies studied for radiological contaminants. In addition to nuclear facilit...

Coastal infrastructure has increasingly become more vulnerable to flooding. While many studies have shown that extreme events such as storm surge threaten to be ever more costly, less damaging but more frequent flood events remain understudied but potentially carry a comparable l...

The Lake Michigan Ozone Study 2017 (LMOS 2017) in May and June 2017 enabled study of transport, emissions, and chemical evolution related to ozone air pollution in the Lake Michigan airshed. Two highly instrumented ground sampling sites were part of a wider sampling strategy of a...

Airborne particulate matter (PM) is a pollutant of concern not only because of its adverse effects on human health but also on visibility and the radiative budget of the atmosphere. PM can be considered as a sum of solid/liquid species covering a wide range of particle sizes with...

New results are presented from wind tunnel studies performed at the United States Environmental Protection Agency (U.S. EPA), which include cases with solid roadside barriers of varying heights and cases with varying distances between the line source (roadway) and a 6-m...

Air pollution is recognized as causal factor in cardiovascular disease (CVD) and is associated with multiple CVD risk factors. Substantial research effort has been invested in understanding the linkages between genetic variation and CVD risk, resulting in over 50 CVD-associated g...

Changes in temperature, precipitation, sea level, and coastal storms will likely increase the vulnerability of infrastructure across the United States. Using three models that analyze vulnerability, impacts, and adaptation, this paper estimates impacts to railroad, roads, and coa...

Many regions in China experience air pollution episodes because of the rapid urbanization and industrialization over the past decades. Here we analyzed the effect of emission controls implemented during the G-20 2016 Hangzhou summit on air quality. Emission controls included a fo...

Changing environmental conditions are forcing natural resource managers and communities to adapt their strategies to account for global shifts in precipitation, temperature, sea level and more, all of which are occurring in addition to local human impacts. Adapting to threats fro...

Particulate matter mass (PM), trace gaseous pollutants, and select volatile organic compounds (VOCs) with meteorological variables were measured in Logan, Utah (Cache Valley) for > 4-weeks during winter 2017 as part of the Utah Winter Fine Particle Study (UWFPS). Higher PM levels...

With increasing population, rapid urbanization and increased migration to cities, the local impacts of increasing transportation and industrial-related air pollution are of growing concern worldwide. Elevated air pollution concentrations near these types of sources have been link...

We propose a dispersion model to characterize the impact of an upwind solid noise barrier next to a highway on air pollution concentrations downwind of the road. The model is based on data from wind tunnel experiments conducted by Heist et al. (2009). The model assumes that the...

On-road emissions sources degrade air quality, and these sources have been highly regulated. Epidemiological and environmental justice studies often use road proximity as a proxy for traffic-related air pollution (TRAP) exposure, and other studies employ air quality models or sat...
