description: "Because of concerns about human health and aquatic ecological effects, atrazine, one of the most widely used pesticides in North America and other corn-growing regions of the world, was the focus of a United States Environmental Protection Agency (USEPA) Special Review. The USEPA requested information relating to ecological impacts, and subsequently, an independent, multidisciplinary panel, the Atrazine Ecological Risk Assessment Panel, conducted a comprehensive aquatic ecological risk assessment of atrazine. The Panel submitted a report to the USEPA in 1995 and published its results in 1996. In order to update the risk assessment and data, a select group of ecotoxicologists, environmental chemists, and modelers from academia and independent consulting organizations in the U.S. and Canada assembled to create the 1999 Atrazine Ecological Risk Assessment Panel. The interdisciplinay panel worked to update the risk assessment and to incorporate new data and elements of a new the tiered probabilistic risk assessment process described by the Ecological Committee on FIFRA Risk Assessment Methods (ECOFRAM). Seeing an opportunity to test some of the ECOFRAM recommendations, the Panel developed the assessment as a case study for the ECOFRAM process. This peer-reviewed publication presents the results of the updated atrazine risk assessment. About the Authors Jeffrey M.
