Abstract: | A review of the scientific literature was conducted on the environmental toxicology, chemistry, fate, and effects of the herbicide tebuthiuron on a variety of water uses in Canada. These uses include raw water for the drinking water supply, freshwater and marine life, crop irrigation and livestock watering, recreational water quality and aesthetics, and industrial water supplies. This information was critically evaluated and used to derive water quality guidelines for the protection of these major uses of water in Canada (see Table A on next page). © 1997 by John Wiley & Sons, Inc.
