A presentation by Dr. Tyrone Hayes on pesticides, the link between amphibian declines and cancer, and what you should know.
Thursday, March 8th, 7PM
Mary Townes Science Center, NC Central University, Durham
Webcast available

Dr. Tyrone Hayes is a professor at UC Berkeley whose groundbreaking research has linked very low concentrations of the herbicide atrazine, a common water contaminant in agricultural areas, to hermaphrodism and other serious deformities in frogs. His research makes a compelling case that pesticides are a major contributor to the decline in amphibian populations across the country, and provides vital background for new science connecting exposure to hormone-mimicking pesticides like atrazine with serious human health problems like prostate cancer, breast cancer and declining sperm count.  His story is also a chilling tale of corporate influence on the scientific research that informs our nation’s laws and regulations.

Born and raised in South Carolina, Dr. Hayes became the unwitting star in the drama of atrazine’s recent re-registration by the US EPA. While atrazine has been banned or restricted in several European and African countries because of health and environmental concerns, it is still a very common herbicide in the U.S. – more than 76 million pounds are applied in this country annually.  Its manufacturer, Syngenta, has fought hard to keep atrazine on the market.  It is used on two-thirds of American corn and sorghum fields, 90 percent of sugar cane fields, and also on residential lawns, golf courses and Christmas-tree farms. Atrazine is a ubiquitous pollutant of ground and surface water, especially in regions of heavy use in the Midwest and Southeast, and contamination has been found as far as 600 miles away from the nearest site of application.  Tyrone Hayes persisted in publishing his research even in the face of the manufacturer’s campaign to silence him.

We hope you can join us for Dr. Hayes’s presentation at NC Central University in Durham on Thursday, March 8th. He is an energetic and inspiring speaker with a very important message to share about the public’s stake in environmental decision-making, and the need for an approach to chemical regulation based on precaution. If you can’t make the presentation in Durham, you can still hear his talk: Dr. Hayes’ presentation will be available by webcast over the Internet live and for several days afterwards. If you’re interested in joining a local viewing of his talk, or in hosting one at your home, organization, school or church, please contact Billie Karel at (919) 833-1123, or at .

In one of Dr. Hayes’ published lab studies, adult male frogs of the species X. laevis exposed to atrazine at low levels - 25 parts per billion - showed an average 10-fold decrease in testosterone production compared to unexposed males, giving them testosterone levels the same or even a below those of unexposed females.
