Emma Rosi is advancing our understanding of how land use, urbanization, and climate change shape freshwater ecosystems, with projects exploring environmental contaminants such as pharmaceutical and personal care products, aging wastewater infrastructure, environmental implications of agricultural GMOs, and the effects of dams.
Rosi directs the Baltimore Ecosystem Study (BES), a National Science Foundation Long Term Ecological Research site. As part of BES, Rosi is exploring the role that failing wastewater infrastructure plays in polluting streams and creating antibiotic-resistant ‘superbugs’. She is also revealing how prescription and illicit drugs that enter our waterways impact freshwater quality and aquatic life.
In addition to her work on human-driven threats to freshwaters, Rosi co-leads a long-term project, in collaboration with Yale University, investigating how wildebeest and hippos shape the food web in the Kenyan reach of Africa’s Mara River.
Rosi is a leader in the field of novel and emerging freshwater contaminants and serves on the Ecological Processes and Effects Committee of the US Environmental Protection Agency’s Science Advisory Board. She also sits on the editorial board of the journal Ecosystems and is a reviewer for the National Science Foundation.
Discover what happens when animals like trout and platypus are exposed to drugs in streams. And learn how Emma Rosi and her team are working to understand big picture impacts, including what we can do to stem the tide of pharmaceuticals and protect rivers and streams globally.
With every flush, the drugs we use go down the drain. Many are not filtered out by wastewater treatment, leaving streams and rivers awash in everything from painkillers and antidepressants to amphetamines and illicit drugs.
Agricultural and sewage pollution can cause low-oxygen conditions and fish kills in rivers. A study published in Nature Communications reports that hippo waste can have a similar effect in Africa’s Mara River.
Antibiotic resistance and pharmaceuticals polluting our waterways is a growing crisis. In this episode of PBS's To The Contrary, Cary's Emma Rosi talks about how untreated sewage contaminated with antibiotics and personal care products is affecting water supplies.
