Book excerpt: "Malathion is a registered insecticide and acaricide used on a wide variety of sites including agricultural and non-agricultural sites. In 2018 (the most recent year for which data are available), over 25 000 kg of malathion was sold in Canada. Malathion may be released into surface water or soil as runoff from the application site. Malathion is not usually found in drinking water sources in Canada. Low levels of malathion have been found in several Canadian provinces. The maximum reported concentrations are well below the MAC. Malathion is rarely detected in foods"--Executive summary.

Download or read book Canadian Water Quality Guidelines for the Protection of Aquatic Life written by Canada. Environment Canada and published by National Guidelines and Standards Office. This book was released on 2003 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of Canadian water quality guidelines for the nitrate ion for the protection of aquatic life. It contains a review of technical background information on the chemical & physical properties of nitrate & nitrate salts, the nitrogen cycle, natural & anthropogenic sources, fate & behaviour of nitrate in the environment, nitrate environmental concentrations, and effects of nitrates on aquatic organisms (including fish, plants, invertebrates, and semi-aquatic mammals & birds). The final section sets out nitrate concentration guidelines to protect fresh & marine water quality and aquatic life, and provides guidance on the application of the guidelines. Appendices include tables that summarize freshwater & marine toxicity studies.
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-11-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Download or read book Herbicides and Plant Physiology written by Andrew H. Cobb and published by John Wiley & Sons. This book was released on 2011-06-09 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides make a spectacular contribution to modern crop production. Yet, for the development of more effective and safer agrochemicals, it is essential to understand how these compounds work in plants and their surroundings. This expanded and fully revised second edition of Herbicides and Plant Physiology provides a comprehensive and up-to-date account of how modern herbicides interact with target plants, and how they are used to manage crop production. In addition, the text: Provides a current account of the importance of weeds to crop yield and quality; Describes how new herbicides are discovered and developed; Examines precise sites of herbicide action and mechanisms of herbicide selectivity and resistance; Reviews commercial and biotechnological applications, including genetically engineered herbicide resistance in crops; Suggests new areas for future herbicide development; Includes many specially prepared illustrations. As a summary of diverse research information, this second edition of Herbicides and Plant Physiology is a valuable reference for students and researchers in plant physiology, crop production/protection, plant biochemistry, biotechnology and agriculture. All libraries in universities, agricultural colleges and research establishments where these subjects are studied and taught will need copies of this excellent book on their shelves.
