Canadian Water Quality Guidelines For Cyanazine

"A review of the available literature on the use, environmental fate, persistence and toxicity of the triazine herbicide cyanazine was conducted"--Abstract.

Cyanazine is a triazine herbicide used extensively in Canada for post-emergence weed in crops. This report describes the chemical's physical/chemical characteristics, its use & sources in the environment, environmental concentrations detected in water & food, analytical methods & water treatment technology, and health effects. It then presents a guideline for its maximum acceptable concentration in drinking water, along with the rationale for the guideline.

Update to the Canadian Water Quality Guidelines, giving guidelines for amounts of picloram, metribuzin and cyanazine in raw water for drinking, recreational water, freshwater for aquatic life, agricultural uses, and industrial water supplies. Background information on uses and production, sources and pathways, environmental concentrations, and forms and fates in the aquatic environment are also included.

'A literature review was conducted on the uses, fate, and effects of simazine on raw water for drinking water supply, freshwater aquatic life, agricultural uses, recreational water quality and aesthetics, and industrial water supplies"--Abstract.

Editions of these guidelines are prepared following a thorough review of the scientific, technical and medical literature on new parameters and on parameters whose guidelines require revision. This 6th edition includes the guidelines approved by the Conference of Deputy Ministers of Health as of March 1995. No evidence has been presented that would warrant changing the values proposed in the last edition. These values have, therefore, been adopted and are presented in this edition as confirmed guidelines. The guidelines and recommendations listed are intended to apply to all drinking water supplies, public and private, however, they should not be regarded as legally enforceable standards unless promulgated as such by the appropriate agency. This document provides an explanation of terms, a description of microbiological characteristics, chemical and physical parameters, and radiological characteristics. It also includes a list of parameters under review or scheduled for review.
