Book Description
Nitrilotriacetic acid (NTA) is an important chelating agent compound with many industrial applications, notably in detergents. It is present in the environment primarily as a result of its release in sewage. This report describes the physical/chemical characteristics of NTA, its use & sources in the environment, environmental concentrations detected in water, analytical methods & water treatment technology, and health effects (including toxicity & carcinogenicity). It then discusses the risk classification of NTA and presents a guideline for the maximum acceptable concentration of NTA in drinking water, along with the rationale for the guideline.

Book Description
During the 1960s, inland bodies of water in North America and Europe experienced a dangerous transformation. Nutrients were dumped into the lakes, causing chain reactions which severely impacted on lake environments. The excessive increase into inland waters through human activity, known as cultural eutrofication, emerged as a dominant problem. Massive algae blooms drifted in overnourished lakes, depleting oxygen, damaging fish stocks, and transforming the water's ecosystem. In Lake Erie Rehabilitated, historian William McGucken presents a comprehensive account of the most notorious international incident of cultural eutrophication---Lake Erie. With the assistance of the International Joint Commission, Canada and the United States diagnosed phosphorous as the primary cause of the problem and, in a unique cooperative effort, reduced input to the lake from municipal and industrial wastewater plants and agricultural lands. Public pressure and government regulation encouraged the reluctant detergent industry to produce alternative detergents and, finally, reduced the input of phosphorous to targeted levels. Lake Erie is now rehabilitated, but its history over the last three decades demonstrates the importance of maintaining an environmental balance. Meticulously researched and documented, this book will appeal to environmentalists, historians, and readers who seek to understand the Great Lakes ecosystem, environmental issues, and environmental regulation.
