The Final ecosystem goods and services (FEGS) concept has become increasingly valuable for identifying and evaluating important trade-offs in estuarine management, yet the translation of FEGS science into policy is limited by a need for meaningful reference points that facilitate...

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...

The RESES team worked, with extensive input from the community, to identify the ecosystem services that the Ouachita River provide and how that contributes to the community&rsquo;s well-being. The work began by identifying the community&rsquo;s values and goals and how they contr...

Evaluating long-term contaminant effects on wildlife populations depends on spatial information about habitat quality, heterogeneity in contaminant exposure, and sensitivities and distributions of species integrated into a systems modeling approach. Rarely is this information rea...

Understanding saltwater intrusion into freshwater coastal wetlands requires long-term historical salinity data, which are often not available in most tidal river systems. This study developed an artificial neural network (ANN) modelling tool to elucidate the relationship between ...

Gulf Ecology Division research ecologist Dr. Deborah Santavy, along with Susan Jackson from the Office of Water&rsquo;s Office of Science and Technology (OW-OST), presented a webinar on July 16, 2019 to update our NOAA partners in the Coral Reef Conservation Program on the fish a...

oral presentation based off of multiple abstracts already cleared on this topic describing the chemistry and toxicology of combustion emissions from various sources.&nbsp; Conceptual Approach.&nbsp; Compare the relative cardiopulmonary toxicity and mutagenicity of smoke either fr...

Many aqueous film forming foam (AFFF) delivery systems in aircraft hangars and firefighting vehicles may require thorough cleaning to avoid ongoing environmental impacts from residual per- and polyfluoroalkyl substances (PFAS) within those systems. Though replacement AFFF formula...

Background: Extreme heat events from climate change are classified as the leading cause of weather-related death in the United States and are associated with cardiovascular morbidity and mortality. Potential synergistic effects of housing (ie. psychosocial stress) with extreme he...

EPA&rsquo;s Endocrine Disruptor Screening Program (EDSP) was established in 1998 to identify chemicals that disrupt human endocrine system signaling. EDSP has the potential to support the regulation of pesticides under FIFRA, the Federal Insecticide, Fungicide, and Rodenticide Ac...

In 2014 a new Chesapeake Bay Watershed Agreement was adopted that included headwater states for the first time and outlined goals for implementation of several BMPs focused on restoration and conservation of vital habitats. At the watershed scale, however, implementation goals as...

Large-scale disasters have the potential to generate a significant amount of waste. For example, Hurricane Katrina and the Joplin Missouri tornado resulted in 100 million and 1.5 million cubic yards of waste, respectively. Man-made chemical, biological, radiological, or nuclear (...

Wildland fire is a major global driver in the exchange of aerosols between terrestrial environments and the atmosphere. This exchange is commonly quantified using emission factors or the mass of a pollutant emitted per mass of fuel burned. However, emission factors for microbes a...

The 3-30-300 rule offers benchmarks for cities to promote equitable nature access. It dictates that individuals should see three trees from their dwelling, have 30 % tree canopy in their neighborhood, and live within 300 m of a high-quality green space. Implementing this demands ...

Background:&nbsp;&nbsp;Tissue fusion is a mechanism involved in the development of the heart, iris, genital tubercle, neural tube, and palate during embryogenesis. Failed fusion of the palatal shelves could result in cleft palate (CP), a common birth defect. Organotypic models co...

This presentation contributes to the SoCal Pb symposium which seeks to raise awareness, share knowledge, and discuss actionable next steps towards solutions to reduce lead risk in LA.

Microscopy is often the first step in microplastic analysis and is generally followed by spectroscopy to confirm material type. The value of microscopy lies in its ability to provide count, size, color, and morphological information to inform toxicity and source apportionment. To...

Quality assurance and quality control (QA/QC) techniques are critical to analytical chemistry, and thus the analysis of microplastics. Procedural blanks are a key component of QA/QC for quantifying and characterizing background contamination. Although procedural blanks are becomi...

Fires that occur in the wildland urban interface (WUI) often burn structures, vehicles, and their contents in addition to biomass in the natural landscape. Because these fires burn near population centers, their emissions may have a sizeable impact on public health, necessitating...

Metals and metalloids are widely used in producing plastic materials as fillers and pigments, which can be used to track the environmental fate of real-life nanoplastics in environmental and biological systems. Therefore, this study investigated the metal and metalloids concentra...

Overview presentation on ORD&rsquo;s Technical Assistance Program for Emerging Contaminants

This presentation provides a critical review of state and federal initiatives and peer-reviewed literature to define best practices for managing PFAS-containing solid wastes and identify data gaps to guide future research. The objective is to inform stakeholders about waste-deriv...

To present EPA PFAS research to the primacy agency and small drinking water utilities in Idaho.&nbsp;

Introduction: Studies of gastrointestinal physiology and the gut microbiome often consider the influence of intestinal region on experimental endpoints. However, this same consideration is not often applied to the gut metabolome. Understanding the contribution of gut regionality...
