Available in PDF, EPUB and Kindle. Book excerpt: An in-depth look at the most promising technology for metal remediation. With current cleanup methodologies offering no real solution to the serious environmental implications of toxic metal contamination, there is a growing need among remediation professionals for effective, affordable, nonpolluting alternatives to energy-intensive engineering processes. This book presents one such promising alternative-the extraordinary new technology of phytoremediation. Through first-rate contributions from the top scientists in the field, Phytoremediation of Toxic Metals surveys worldwide pioneering efforts in the use of plants to treat contamination of such metals as lead, cadmium, chromium, and even radionuclides. The authors explore all major aspects of the technology-how it utilizes the metal-accumulating properties of selected or engineered plants to remove toxic metals from soils and water, how to transfer knowledge from the laboratory to the field, and what methods are most viable for commercial application. Complete, state-of-the-art coverage includes: * The economic advantages of plant-based technology * Regulatory considerations for future phytoremediation * Phytoextraction, phytostabilization, and phytofiltration of toxic metals * Photostabilization of metals using hybrid poplar trees * Phytovolatilization for the special case of mercury and selenium * The biological mechanisms of metal-accumulating plants

Download or read book The Determination of Arsenic in Rice by Acid Digestion and Atomic Absorption Spectroscopy for the Purpose of Developing an Undergraduate Laboratory Experiment written by Matthew van der Wielen and published by . This book was released on 2018 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic is a non-essential trace element that is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC). Arsenic contamination poses a great risk to those who get their drinking water from underground wells, especially in many Asian countries with naturally high arsenic concentrations in the soil. When contaminated water is used to grow crops like rice, significant bioaccumulation of arsenic in the rice can lead to serious health risks to those who rely on rice for most of their caloric intake. The goal of this study was the development of a laboratory for undergraduate analytical chemistry students. Different rice brands were tested for arsenic concentration under different variables to find the optimal setup for a laboratory. Rice samples were taken in 1, 2.5, and 5 gram measurements and digested using either a modified 3050B method or a simple acid digestion. Rice brands were chosen for an even spread of whole rice grains versus rice cereals, and were analyzed using Atomic Absorption Spectroscopy (AAS). Of the rice brands tested, Gerber's Baby Rice Cereal and Sri Lankan whole grain rice performed well across digestion and analysis, with final concentrations of 83.07 μg/kg and 60.70 μg/kg, respectively. The 2.5 gram samples were found to digest and analyze better than 1 or 5 gram samples, as they did not overflow their containers or provide erroneous data during analysis. Neither digestion method showed a consistent trend across rice samples, and digestion of standards alongside each trial showed the digestion methods to be nearly chemically equivalent.
