Dr. Rosi’s research focuses on how human activities affect aquatic life and water quality in diverse ecosystems around the world. She is particularly interested in novel and emerging contaminants such as pharmaceuticals, and also studies the effects of nutrient enrichment. In addition to water quality, her work examines aquatic food webs (invertebrates and fishes), and the role of the hippopotamus in nutrient cycling. Her research seeks to inform sound stewardship of freshwater resources, and she often speaks to the public and policymakers. She serves on the Ecological Processes and Effects Committee of the US Environmental Protection Agency’s Science Advisory Board.
Globally, direct modification of rivers for hydropower generation is one of the most dramatic effects humans have had on large river ecosystems.
Our understanding of nutrient cycling in large river ecosystems is currently limited.
Our understanding of the effects of Global Climate Change on stream ecosystems is limited.
Research examining the cycling of novel allochthonous carbon, i.e. agricultural crop by-products, in Midwestern agricultural streams.
The widespread use of novel contaminants, such as pharmaceuticals, have unknown consequences for stream ecosystems.
The Cary Institute has taken a lead role in developing programs in urban ecology aimed at understanding urban ecosystems, one of Earth's fastest growing environments.
Pharmaceutical drugs and personal care products are showing up in rivers and streams throughout the United States and the rest of the world. What effects are they having on the environment?
A wide range of drugs - everything from antibiotics to antihistamines, are showing in our rivers, streams and water supply and it is having an impact on our environment. What can we do about it?
Aquatic ecologist Emma Rosi talks about pharmaceuticals in waterways and research into the ways they may be affecting aquatic life.
A panel of experts, including Cary Institute aquatic ecologist Emma Rosi, discuss the issue of pharmaceutical pollution at a Pennsylvania Senate Environmental Resources Committee hearing.
Gwynns Falls in Baltimore has a drug problem. Researchers found amphetamines, opioids and morphine in the water, and that kind of pollution is having an impact on the aquatic food chain. WBAL-TV reports.
The Grand Canyon Reach of the Colorado River is breathtaking and remote. For hundreds of miles, the rugged landscape renders the river virtually inaccessible to people. Those intrepid enough to explore the area are treated to red rocks, blue skies, and meandering waters.
Most of us don't spend a lot of time thinking about our wastewater. We want our toilets to flush and our dirty wash water to go down the drain. We assume this water is efficiently routed to a treatment facility, where it is cleaned up and returned to the environment. But reality doesn't measure up to our expectations.
Freshwater ecologist Emma Rosi-Marshall explores how pharmaceutical drugs and personal care products are polluting our nation's rivers and streams—with consequences for sensitive aquatic life and drinking water supplies.
EPA and U.S. Geological Survey scientists analyzed treated water samples from 25 U.S. utilities. They found that more than 1/3 contained chemicals not regulated by the federal Safe Drinking Water Act.
Managing fish in human-altered rivers is a challenge because their food webs are sensitive to environmental disturbances.
Cary scientists study the effect various contaminants have on aquatic ecosystems at an Artificial Stream Facility that recreates stream conditions in a controlled laboratory setting.
Around half of liquid soaps now contain the chemical triclosan, as do toothpastes, deodorants, cosmetics, and other personal care products.
Pharmaceutical pollution is found in waters throughout the world. Causes include sewage overflows, aging infrastructure, and agricultural runoff. Even when waste water makes it to sewage treatment facilities, they aren't equipped to remove most pharmaceuticals.
My colleague Emma Rosi is an aquatic ecologist at the Cary Institute. One of her research projects involves an endangered fish called the humpback chub. She and her team spend a lot of time counting insects in the Colorado River downstream of the Glen Canyon Dam. You might think her time would be better spent counting the actual fish, but her approach will provide us with a lot more information.
We are a nation of pill poppers. From statins to lower cholesterol to antidepressants to lift our mood, more than half of Americans are currently taking a prescription drug. Some twenty percent of us are taking three different prescriptions daily.
