Some air sensors on the market today fail to deliver the performance expected and/or advertised.&nbsp; Thus, there is still a role for performance testing in both field and controlled laboratory environments to better inform consumers of their likely real-world performance capabi...

In July 2023, USEPA will host an international workshop bringing together experts to discuss air sensor quality assurance strategies.&nbsp; During one session, sensor manufacturers and data aggregators will be invited to speak about the approaches they currently employ (or are un...

This presentation will orient undergraduate students to ongoing air quality research in Robeson County and EPA tools for air quality research. The students will be expected to contribute to this research as part of their studies at UNC's department of Environmental Sciences and E...

Ozone-induced acute lung injury and inflammation following one or two days of exposure are not evident if ozone exposure continues for 3 or more days. While a one-to-two-day exposure can induce neutrophilic inflammation, lung protein leakage, and airway irritation, real-life expo...

Toxicological work suggests gestational parent (GP) diet may modify the effect of ambient pollutants on birth outcomes. We assessed risk of preterm birth in humans in relation to fine particulate matter (PM2.5), ozone (O3), and nitrogen dioxide (NO2) and whether associations vary...

The fourth phase of the Air Quality Model Evaluation International Initiative (AQMEII4) is conducting a diagnostic intercomparison and evaluation of deposition simulated by regional-scale air quality models over North America and Europe. In this study, we analyze annual AQMEII4 s...

Low-cost sensors (LCS) are increasingly being used to measure fine particulate matter (PM2.5) concentrations in cities around the world. The PurpleAir is one of the most commonly deployed LCS with ~ 15,000 monitors deployed in the United States. PurpleAir measurements are widely ...

Air pollution is a leading environmental health concern and early life exposures may have life-long implications. Prenatal air pollution exposure has been reported in association with blood pressure (BP) percentiles and elevated BP in infants and children, which are important pre...

As part of an analysis performed under the auspices of the International Workshop on Genotoxicity Testing (IWGT) in 2017, we and others showed that there was redundancy among the bacterial strains specified in the Organization for Economic Cooperation and Development (OECD) Test ...

Per- and polyfluorinated alkyl substances (PFAS) compose a group of thousands of synthetic chemicals with advantageous physical and chemical properties for consumer and industrial applications. PFAS have stain-resistant, water-resistant, non-stick, and lubricating properties and ...

While high-resolution MS (HRMS) can be used for identification and quantification of novel per- and polyfluorinated alkyl substances (PFAS), low-resolution MS/MS is the more commonly used and affordable approach for routine PFAS monitoring. Of note, perfluoropentanoic acid (PFPeA...

Annual updates will be made to GLIMPSE/GCAM-USA and shared with users and partners. Updates are expected to include integration of new versions of GCAM, addition of policy levers, and enhancements to usability. &nbsp;

This observational study gathered data from 73,425 U.S. Veterans in multiple domains including the Veterans Affairs Clinical Assessment, Reporting and Tracking (VA-CART) program, inpatient and outpatient laboratory electronic health records, and geospatial information.&nbsp; PM2....

Several thousand intentional and unintentional chemical releases occur annually in the U.S., with the contents of almost 30% being of unknown composition. When targeted methods are unable to identify the chemical(s) present, additional approaches like non-targeted analysis (NTA) ...

In line with the theme of the 2023 AMS Annual Meeting of data driving science and informing decisions, this presentation relates to the representation, and increasing relevance, of lightning NOx (LNOx) emissions in numerical studies of atmospheric composition, air pollution, and ...

Background/Aims Exposure to air pollutants is associated with preterm birth (PTB, &lt;37 weeks completed gestation); however, there is limited research on whether these associations are modified by neighborhood-level risk factors. We evaluated whether associations between gestati...

Background/Aims: Native American tribes and Alaska Native Villages (NAT/ANV) have been and continue to be disproportionately burdened by cumulative environmental injustices. In recent years, scholars have highlighted the need to examine cumulative environmental factors on health ...

This report highlights the salient findings from SHC products contributed by a team of ORD investigators from PHITD and CPAD of CPHEA, CCED of CCTE, and ORISE. The SHC research focused on the influences of maternal exposure to chemical and non-chemical stressors, and their intera...

EPA maintains national-level environmentally-extended input-output models in USEEIO. However, these models mask what could be significant domestic variation in supply chains and emissions profiles of goods and services at the state-level.&nbsp;In 2022, EPA published for the first...

Ecosystem goods and services produce the many life-sustaining benefits we receive from nature: clean air and water, fertile soil for crop production, pollination, and flood control. These ecosystem services are important to environmental and human health and to well-being; yet th...

Above ground storage tanks/terminals provide an essential link in the transportation of fuel between national infrastructure (e.g., pipelines) and local distribution points (e.g., gas stations). As part of normal operations, volatile components of refined gasoline/fuels (includin...

Littoral habitat is critical for lake biota, but it is adversely affected by residential shoreland development through the loss and reduced structural complexity of lakeshore vegetation. There currently exists no assessment methodology for evaluating littoral habitat condition of...

This paper describes the results of a four-day&nbsp;next generation emission measurement (NGEM) demonstration study conducted at a midwestern U.S. chemical facility that uses ethylene oxide (EtO), a hazardous air pollutant, in the production of industrial surfactants. The abstrac...

Background/Aims Environmental quality varies between neighborhoods, with lower environmental quality observed in neighborhoods with lower income levels and/or lower proportion of white residents. In the 1940&rsquo;s, the Home Owners Loan Corporation (HOLC) created maps of neighbo...

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