Sigma Xi Presents Speaker on Environmental Carcinogens

April 30, 1998

Geneva, NY — “Environmental Carcinogens: Modes of Action and Reaction in Living Systems” will be the topic of a presentation by Nicholas Geacintov, professor of chemistry at New York University, at 8 p.m. Wednesday, May 13, in room 8, Coxe Hall, on the Hobart and William Smith Colleges campus. The public is invited to attend.

This lecture will describe current knowledge of the multi-step mechanisms by which environmental carcinogens cause cancer. The human body is continuously exposed to chemical carcinogens present in air, food, and water supplies. Once in the body, these generally inert chemicals can be metabolically activated to form highly reactive and dangerous compounds. These compounds can bind to DNA, the genetic material of the cell and, if not removed by cellular repair enzymes, can give rise to mutations and cancer.

The presentation is sponsored by the Geneva Chapter of Sigma Xi, the Scientific Research Society. Sigma Xi is dedicated to honoring scientific accomplishments, encouraging and enhancing appreciation and support of original investigation in science and technology, and fostering a creative and dynamic interaction among science, technology, and society worldwide.
