CANADIAN WATER-QUALITY GUIDELINES FOR TEBUTHIURON

A review of the scientific literature was conducted on the environment al toxicology, chemistry, fate, and effects of the herbicide tebuthiur on on a variety of water uses in Canada. These uses include raw water for the drinking water supply, freshwater and marine life, crop irriga tion and livestock watering, recreational water quality and aesthetics , and industrial water supplies. This information was critically evalu ated and used to derive water quality guidelines for the protection of these major uses of water in Canada (see Table A on next page).
