Contaminants of Concern for Human and Environmental Health

Group of children and adults holding Lake Apopka Farmworker Memorial Quilt

Thursday, December 3, 2020
11:00 a.m. to 12:00 p.m. (Pacific Time)




Check out this video to watch the Toxicology and Societies: The Impacts of Chemicals in our Lives.

Please join us for the next speaker in our series on Toxicology and Societies: The Impacts of Chemicals in our Lives. Dr. Nancy Denslow, a professor in the Department of Physiological Sciences and in the Center for Environmental and Human Toxicology at the University of Florida, will talk about the use of pesticides in Florida. She will present on linkages between pesticide exposures and chronic diseases like lupus.

Our vision in developing this series was to support a better understanding of something that affects all of us. There are over 300,000 chemicals being produced and used in almost everything we wear, eat, and drink. How can you ever hope to understand when and where you or your family might be at risk from some of these chemicals? The short answer is, you can’t know everything about all of these substances, but you can learn more about how toxicology (the study of toxic substances) affects you and your society.

This seminar series aims to help you better appreciate, understand, and evaluate the many ways that manufactured chemicals interact with all humans on Earth.

More information about the speaker series is available here.

Dr. Nancy Denslow


Nancy Denslow is a professor in the Department of Physiological Sciences and in the Center for Environmental and Human Toxicology at the University of Florida. She received her Ph.D. from the University of Florida in Biochemistry and Molecular Biology. Nancy has pioneered the use of molecular technologies for environmental toxicology especially focusing on high throughput in vitro assays, biomarker development and toxicogenomics approaches for evaluating contaminants of emerging concern. She has specialized in assessing the effects of organochlorine pesticides and endocrine disruptors that are found at relatively high levels in the environment. Nancy has over 250 peer-reviewed publications. She has received several awards for her research including the Founders Award from the Society of Environmental Toxicology and Chemistry. In addition to this society, she is also a member of the Society of Toxicology, and the Association of Biomolecular Research Facilities, a society devoted to the “OMICS” technologies. Nancy’s research has received funding from EPA, NSF, USGS and NIH.
