Waste water treatment plants (WWTPs), as well as industrial and agricultural operations release complex mixtures of anthropogenic chemicals that negatively affect surface water quality. Previous studies have shown that exposure to such complex chemical mixtures can produce adver...

We estimate the damage costs associated with the institutional nitrogen (N) footprint and explore how this information could be used to create more sustainable institutions. Potential damages associated with the release of NOx and N2O to air and release of N to water were estima...

Background/Question/Methods: Release of N to air, land and water has a host of effects on human health, ecosystems and the economy, many of which scientists and economists are just beginning to develop methods to quantify. In order to understand the broader connections to sustai...

There is significant concern regarding potential impairment of fish reproduction associated with exposure to endocrine disrupting chemicals (EDCs). Aromatase is a steroidogenic enzyme involved in the conversion of androgens to estrogens. Inhibition of aromatase can reduce levels ...

Swimming in natural waters (e.g., oceans, lakes, rivers) is one of most popular recreational activities in the United States. However, exposure to pathogens (e.g., Salmonella spp., Shigella spp., Cryptosporidium, Giardia, adenovirus, norovirus) in recreational waters can lead to ...

As more success is achieved in restoring lakes and estuaries from the impacts of nutrient pollution, there is increased opportunity to evaluate the scientific, social, and policy factors associated with achieving restoration goals. We examined case studies where deliberate action...

This presentation was an invited keynote address, which was based on a published paper: Gross, C. and J. D. Hagy, 3rd (2017). &quot;Attributes of successful actions to restore lakes and estuaries degraded by nutrient pollution.&quot; J Environ Manage 187: 122-136. As more succes...

Many hectares of intensively managed Douglas-fir (Pseudotsuga menziesii Mirb. Franco) stands in western North America are fertilized with nitrogen to increase growth rates. Understanding the mechanisms of response facilitates prioritization of stands for treatment. The objective ...

Increased consumption and improper disposal of prescription medication, such as beta (&beta;)-blockers, contribute to their introduction into waterways and pose threats to non-target aquatic organisms. Beta-blockers are widely prescribed for medical treatment of hypertension and ...

Mangrove systems are known carbon (C) and greenhouse gas (GHG) sinks, but this function may be affected by global change drivers that include (but are not limited to) eutrophication, climate change, species composition shifts, and hydrological changes. In Puerto Rico&amp;rsquo;s...

&beta; blockers are prescription drugs used for medical treatment of hypertension and arrhythmias. They prevent activation of adenylate cyclase and increases in blood pressure by limiting cAMP production and protein kinase A activation. After being taken therapeutically, &beta; b...

In recent years, the use of in situ thermal remediation technologies at Superfund Sites in the United States has increased substantially. With this, comes new challenges while the overall goal of reducing contamination to very low levels remains. My experience has been that the...

Researchers have frequently sought to use environmental archives of sediment, peat and glacial ice to try and assess historical trends in atmospheric mercury (Hg) deposition to aquatic ecosystems. While this information is valuable in the context of identifying temporal source tr...

Product Description:Evaluation of the potential effects of complex mixtures of chemicals in the environment is challenged by the lack of extensive toxicity data for many chemicals. However, there are growing sources of online information that curate and compile literature reports...

Estuaries are among the most productive ecosystems in the world, providing unique habitat for freshwater and marine species as well as valuable social and economic benefits. The wealth of ecosystem goods and services from estuaries has led to growth and development of human commu...

The health of estuarine ecosystems is often influenced by hydraulic and nutrient loading from upstream watersheds. We examined four decades of monitoring data of nutrient export into the Indian River Lagoon and San Francisco Bay, both of which have received considerable attentio...

The increase in the use of nanoscale materials in consumer products has resulted in a growing concern of their potential hazard to ecosystems and public health from their accidental or intentional introduction to the environment. Key environmental, health, and safety research nee...

Being &ldquo;connected&rdquo; is an essential component of human health. Connections between people allow for communication, trade and other critical social interactions. Similarly, connections are important for the ecosystems that make up our environment. While &ldquo;aquatic co...

Recent efforts to develop and evaluate regional and global chemical transport models reveal major gaps in atmospheric deposition monitoring. First, in contrast to northern North America, western Europe, and Asia, vast land areas in Latin America, Africa, and Australia remain unde...

Recent runoff events have had serious repercussions to both natural ecosystems and human infrastructure. Understanding how shifts in storm event intensities are expected to change runoff responses are valuable for local, regional, and landscape planning. To address this challenge...

1. We investigated the potential of cross-scale interactions to affect the outcome of density reduction in a large-scale silvicultural experiment. 2. We measured tree growth and intrinsic water-use efficiency (iWUE) based on stable carbon isotopes (&#61540;13C) to investigate the...

High throughput screening assays able to detect chemical interactions with specific biological targets are increasingly being used to identify chemicals that could be hazardous to humans or wildlife. Most of these assays examine interaction with mammalian proteins. The present wo...

Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological ...

EnviroAtlas is a web-based tool developed by the EPA and its partners, which provides interactive tools and resources for users to explore the benefits that people receive from nature, often referred to as ecosystem goods and services.Ecosystem goods and services are important to...
