Adsorption of Metals by Geomedia II serves as a needed resource for this topic which has received much attention during the past 25 years. The book provides an in-depth review of the field, followed by numerous chapters that document the current status of adsorption research for a variety of metals by geomedia ranging from individual minerals to sediments and soils. Adsorption mechanisms are detailed and precipitation is presented as a distinct sorption process. Virtually all factors affecting the extent of metal adsorption are examined, including the effects of selected anions, competition among metals, pH, metal concentration, loading, variable metal adsorption capacity, ionic strength, hydrogen exchange and stoichiometry, and solids concentration. A variety of adsorption models are briefly presented and some are used to extend laboratory studies to field sites. This is a compilation of 25 peer reviewed papers from among the 60+ platform and poster presentations of the symposium "Adsorption of Metals to Geomedia II" at the American Chemical Society (ACS) Meeting, March 27-29, 2006 in Atlanta, Georgia, USA. This symposium is a follow-up to the original held in 1996.Learn the tools and techniques from leading academics and industry expertsOne stop practical resource and guide for those in the fieldKeep informed and up to date on all the latest advancements in technology

How do we provide for and nurture millions of people without destroying the planet in the process? Author Doug Kent, an environmental specialist, believes a vital element in the solution is recognizing that urban landscapes are an essential partner in everyone’s wellbeing. He argues that urban landscapes can and must work harder.Urban landscapes can provide part of our energy needs, help cool our buildings and public spaces, help us make the most of our precious water. They can also help combat air pollution and reduce the likelihood of allergies and asthma. They can provide landscape materials and even contribute to our timber supply. Doug also advocates turning landscapes into a food source, and/or a perfumery, pharmacy, soap shop, or craft store.Doug has over 12 years of research in this book. He has spent years doing literature reviews, and many more years concocting, consuming, crafting, distilling, propagating, retting, sawing, sowing, and weaving its many recommendations. He has also travelled the length and width of California many times to interview the people and businesses already doing this incredible work.Regenerating Essential Goods and Services is not a manifesto. It is a user’s manual. You are the creative and energetic force that will ultimately drive sustainability and regeneration. Let’s go.
