Letter to the Editor in response to our recent publication on unknown organic chemicals in e-cigarette liquids and aerosols
As a response to our recent publication on the use of non-target analysis for the fingerprinting of unknown organic chemicals in e-cigarette liquids and aerosols, a group of four scientists from Juul Labs Inc., one of the e-cigarette manufacturers from which we tested a product from, wrote a letter to the editor which can be accessed here. Our response to the raised criticism can be found here.
Radio Interview about new vaping study on KCRW-FM’s Press Play
Carsten was interviewed by Madeleine Brand, the host of the news and culture show Press Play, on KCRW-FM, one of Los Angeles’ two National Public Radio (NPR) affiliates, about our new vaping paper. The interview can be found here.
New paper on non-target analysis for identification of unknown chemicals in vaping aerosols and e-cigarette liquid covered by Bloomberg News
The paper lead by Mina Tehrani, a Postdoc in the laboratory of our collaborator Ana Rule, which was published in Chemical Research in Toxicology, is discussing the use of non-target analysis based on liquid chromatography – high-resolution mass spectrometry (LC-HRMS) for the detection of previously unknown chemicals in e-cigarette liquids and vaping aerosols. In addition to Mina, Ana and Carsten also Matthew Newmeyer, Postdoc in the Prasse lab, was involved in the research.
Prasse Lab Wins EPA Grant for Research on Potential Risks from Pollutants Found in Biosolids from Wastewater Treatment
Carsten is the principal investigator of a new research project entitled ‘Fate and Transport of Unregulated Organic Contaminants in Biosolids – Development of a Human and Environmental Exposure Risk Framework‘. The co-investigators on the project are Keeve Nachman and Thomas Burke, both in the Bloomberg School of Public Health at Johns Hopkins. More information about the project can be found here.

New perspective article in Nature Sustainability: Reimagining safe drinking water on the basis of twenty-first-century science
Protecting drinking water is tough with an ever-expanding set of chemicals in our environment. Paul Ferraro and I propose an alternative way that leverages recent advances in bioassays, analysis of complex mixtures, and Artificial Intelligence. A free version of the Perspective article is available here.
We propose a new proactive approach (which we call MiAMI – Mixture, Assay, Measure, Innovate) that evaluates drinking water quality more holistically by focusing on complex mixtures instead of a small set of regulated, well-known chemicals that have been studied for decades.
Photo-essay undergraduate class project ‘Environmental Concerns’
As part of Carsten’s teaching activities, he started a new photo-essay blog project in collaboration with Kevin Mick, Professor in the Psychology Department at the Community College of Baltimore County.
This photo-essay blog represents our approach to engage students with environmental issues that are associated with anthropogenic activities in a format that is totally different from their typical experiences in the classroom. The task for participating students is to take a single picture or a series of pictures that highlight an environmental issues that is of concern to them. The pictures are accompanied with a short text paragraph that allows the students to share their personal story about the pictures and how they relate to environmental issues they are uncovering.
PhD student Veronica Wallace wins Scholarship from the Air & Waste Management Association
Congratulations to Veronica for winning the Solid and Hazardous Waste Research Scholarship by the Air & Waste Management Association (A&WMA)!
Johns Hopkins Alliance for Healthier World Grant on Urban Aquaculture
Urban Aquaculture for Climate Justice and Local Food Sovereignty is headed by co-principal investigators Nicole Labruto, an assistant research professor in the Krieger School of Arts & Sciences’ Department of Anthropology, and Carsten Prasse, an assistant professor in the Department of Environmental Health & Engineering at the Whiting School of Engineering.
The project will join with the Black Yield Institute — a Black-led think tank and collective action network that addresses food apartheid — to explore the feasibility of community-led urban aquaculture on the shoreline of the Patapsco River’s Middle Branch in south Baltimore.
NSF Graduate Research Fellowship for Daisy Grace
Congratulations to Daisy Grace, first year PhD student in the Prasse lab, for winning the prestigious NSF Graduate Research Fellowship! Her proposed research will focus on the development of novel approaches for the detection of toxic organic chemicals in (drinking) water.
What Our Wastewater Can Tell Us
Carsten was featured in an article about Wastewater Epidemiology in the Johns Hopkins Magazine.
Carsten is part of a diverse community of researchers, designers, activists, and artists, committed to the imagination and development of alternative ecological futures. We work with the conviction that there are designers everywhere, drawing on communal traditions and practical expertise to forge other worlds of possibility.
