At least four polyfluorinated organic substances (i.e., 4:2-, 6:2-, 8:2- and 10:2- fluorotelomer alcohols; FTOHs) have sufficient vapor pressure (VP) to be designated as vapor-forming chemicals. Based on current guidance, vapor-forming chemicals warrant investigation for vapor in...

It is imperative to develop sampling and analytical methods to characterize FTOHs in indoor air for the development of mass transfer models to quantitatively predict FTOH emissions and transport for exposure assessment and risk management. This standard describes thermal desorpti...

This report summarizes novel air sampling research conducted for the multi-agency Analysis for Coastal Operational Resiliency (AnCOR) program which sought to develop and demonstrate capabilities and strategic guidelines to prepare the US for a wide-area release of a biological ag...

Across the U.S., some individuals and communities are more susceptible to disproportionate harm from climate change due to differences in exposure and vulnerability to climate hazards. This report investigates the projected risks of climate change to socially vulnerable populatio...

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...

Thist is a summary of research conducted by the Environmental Protection Agency (EPA) )to develop a full-scale emissions test method that characterizes the application and post-application emissions from spray polyurethane foam (SPF) insulation The primary objectives of the resea...

In January 2020, the Wildland Fire Leadership Council (WFLC) requested that EPA, in collaboration with scientific staff in the U.S. Forest Service (USFS), the Department of the Interior (DOI) and the National Institute of Standards and Technology (NIST), conduct an assessment ...

Federal Guidance Report No. 16 (FGR 16) provides radionuclide-specific lifetime radiogenic cancer risk coefficients for the U.S. population, based on age- and gender-specific intake rates, dosimetry, and risk models. Risk coefficients are provided for external exposure to radionu...

The U.S. Environmental Protection Agency (EPA) created this document to help existing and planned school communities identify strategies for reducing traffic-related pollution exposure at schools located downwind from heavily traveled roadways (such as highways), along corridors ...

The work is planned in three stages. The first stage is for sensor prototype design involving survey and selection of the bioreceptor and a transduction mechanism, and the development of a prototypic sensor. In the second stage, the lab prototype is put to test with samples from ...

The US Environmental Protection Agency (EPA) has conducted an HIA at the German Gerena Community School in Springfield, MA. HIA is a six-step systematic process that uses an array of data sources, analytic methods and stakeholder input to determine the potential health effects of...

The assessment of environmental exposures for human health is an advancing field, characterized by multiple new methodologic and analytic approaches. The difficulties in examining the many broad-based factors impacting human health outcomes are increasingly recognized, with expos...

A better estimate of overall environmental quality is needed to improve our understanding of the relationship between environmental conditions and human health. Described in this report is the effort to construct an environmental quality index (EQI) representing multiple domains ...

The Watershed Management Optimization Support Tool (WMOST) was developed by the United States Environmental Protection Agency (US EPA) to facilitate integrated water resources management. The new Benefits Module for WMOST enables stakeholders to calculate the value of additional ...

EPA announced the availability of the first external review draft of the <em>Integrated Science Assessment for Sulfur Oxides– Health Criteria</em> for public comment and independent peer review in a November 24, 2015 Federal Register Notice. This draft document provides EPA’s ev...

The Fertilizer Emission Scenario Tool for CMAQ (FEST-C v1.4) is a Java-based interface system that facilitates the integration of agriculture, atmosphere, and hydrology simulations at large scales through the current release of the Spatial Allocator (SA v4.3.2) Raster Tools syste...

Climate change and air pollution are arguably the most significant environmental problems facing the United States and the world over the next decade. There is an urgent need to dramatically curtail emissions of greenhouse gases, including powerful short-lived forcers such as met...

EPA Method TO-15A compiles in a single document the best practices and lessons learned by users of the method over the past 20 years. It has been totally rewritten to address and incorporate improvements in canister, sampling, preconcentration, and analytical instrumentation tec...

Upon completing this course, you will be able to do the following: &bull; Identify why wildfire smoke exposure is a public health and clinical concern. &bull; Identify groups at greatest risk from particle pollution in wildfire smoke. &bull; Explain how particle pollution from wi...

This report describes the state of the science with respect to total Nr deposition budgets in the United States and the research needed to improve these budgets from both a measurement and modeling perspective. The document is intended to serve as a roadmap for research activiti...
