The multivariate AMBI (M-AMBI) is an extension of the AZTI Marine Biotic Index (AMBI) that has been used extensively in Europe, but not in the United States. In a previous study, we adapted AMBI for use in US coastal waters (US AMBI), but saw biases in salinity and score distribu...

This work presents the results of an international interlaboratory comparison on ex situ passive sampling in sediments. The main objectives were to map the state of the science in passively sampling sediments, identify sources of variability, provide recommendations and practica...

The Adverse Outcome Pathway (AOP) framework has emerged to capitalise on the vast quantity of mechanistic data generated by alternative techniques (such as in vitro and in chemico), as well as advances in systems biology, cheminformatics, and bioinformatics. AOPs provide a scaffo...

Due to the ever-increasing number of chemicals coming to market, and the cost of performing traditional in vivo studies, there has been a shift towards the use of less costly alternative techniques. The adverse outcome pathway (AOP) concept has emerged as a scaffold for organisin...

The aggregation and long-term (25 d) sedimentation behaviors of reduced graphene oxide (RGO) and its three successively self-assembled nanohybrids with magnetite (Fe3O4) and zerovalent silver (Ag0) nanoparticles were investigated. The aggregation behaviors of the nanomaterials in...

Epoxy-based materials are widely used for coatings, electronics insulations, and waterproofing applications due to their excellent properties such as excellent adhesion, electrical insulation, and heat resistance along with the strong mechanical property. The making of composites...

Many cities are experiencing long-term declines in population and economic activity. As a result, frameworks for urban sustainability need to address the unique challenges and opportunities of such shrinking cities. Shrinking, particularly in the U.S., has led to extensive vacant...

A morphological defect, a cortical heterotopia, has been observed in the brains of rat pups exposed in utero to moderate doses of the thyroid hormone (TH) synthesis inhibitor propylthioruracil (PTU). TH insufficiency during late gestation/early postnatal period is required to ind...

This webinar, titled &ldquo;EPA&rsquo;s Storm Water Management Model (SWMM)&rdquo;, is scheduled for Tuesday February 20th at 12pm Eastern. This webinar will introduce the Storm Water Management Model (SWMM). SWMM is used throughout the world for planning, analysis, and design ...

Groundwater nitrate contamination affects thousands of households in Oregon&rsquo;s southern Willamette Valley and many more across the USA. The southern Willamette Valley Groundwater Management Area (GWMA) was established in 2004 due to nitrate levels in the groundwater exceedi...

This report explores rainfall-runoff models, their generation methods, and the categories under which they fall. Runoff plays an important role in the hydrological cycle by returning excess precipitation to the oceans and controlling how much water flows into stream systems. Mode...

Urban water systems consist of natural and engineered flows of water interacting in complex ways. System complexity can be understood via mass conservative models that account for the interrelationships among all major flows and storages. We have developed a generic urban water s...

Local, state, federal, tribal and private stakeholders have committed significant resources to restoring Puget Sound&rsquo;s terrestrial-marine ecosystem. Though jurisdictional issues have promoted a fragmented approach to restoration planning, there is growing recognition that a...

Sediment toxicity tests are used for contaminated sediments, chemical registration, and water quality criteria evaluations and can be a core component of ecological risk assessments at contaminated sediments sites. Standard methods for conducting sediment toxicity tests have been...

Examine influence of nutrient availability on life cycle progression and morphology. Step-wise analysis of internal regulators, nutrient constraints, toxin production, and morphology through Cell Isolation.

Six bioretention units (widths 7.1 m) at USEPA&rsquo;s Edison Environmental Center were constructed to evaluate sizing of surface area to watershed area. Three sizes were tested in duplicate with changes in aspect ratio of length from inlet (northern) wall by doubling successive ...

A review of animal illness and One Health and cyanobacteria. Animal illnesses and deaths associated with exposure to toxic cyanobacteria can be sentinel events that inform human health risks.

The US Environmental Protection Agency&rsquo;s (EPA) Index of Watershed Integrity (IWI) is used to calculate and visualize the status of natural watershed infrastructure that supports ecological processes (e.g., nutrient cycling) and services provided to society (e.g., subsistenc...

Nano-zero valent iron (nZVI) due to its high activity towards persistent organic contaminant degradation and heavy metal removal has attracted applications in industrial waste water treatment as well as in situ soil remediation techniques. Enhancement of nZVI&rsquo;s catalytic ac...

In vitro based assays are used to identify potential endocrine disrupting chemicals. Thyroperoxidase (TPO), an enzyme essential for thyroid hormone (TH) synthesis, is a target site for disruption of the thyroid axis for which a high-throughput screening (HTPS) assay has recently ...

Ecological applications of portfolio theory demonstrate the utility of this analytical framework for understanding the stability of commercial and indigenous Pacific Salmon fisheries. Portfolio theory also has the potential to aid in recovery planning for threatened and endangere...

VELMA (Visualizing Ecosystem Land Management Assessments) is an eco-hydrological model that produces visual simulations of many hydrologic and ecological processes over time periods from hours to days to years. The purpose thus far has been used for predicting effectiveness of g...

In 2014, the western Balkans&rsquo; heaviest recorded rains triggered extensive flooding affecting approximately 29,600 km2, or the equivalent of 75% of the study area. Rapid urbanization and the increasing regularity of late-summer droughts in the region likely exacerbated these...
