Pieces of the Puzzle; Does Atrazine Affect the Risk of Cancer?

by Suzanne M. Snedeker, Ph.D.
Cornell Sprecher Institute for Comparative Cancer Research

The PALS modules (Pesticide Applied Learning Series) make current scientific topics on agriculture, the environment and health available to pesticide safety educators and extension agents. Educators can adapt modules for their own use and for presentations to pesticide applicators. This module explores the current scientific evidence of whether exposure to the herbicide atrazine affects the risk of cancer.
