ABSTRACT: The research is focused on the degradation of two endocrine disrupting compounds (EDCs) in zero-valent iron. The endocrine disrupting compounds bisphenol A (BPA) and 17b-estradiol (E2) are chemical compounds that have an adverse effect on the environment, humans, and wildlife. These two chemical constituents are being examined in this research because they are still being used today and continue to impact their surrounding environment. These chemicals are considered persistent, bioaccumulative, and toxic to the environment. The research explores the technological use of zero-valent iron to degrade the chemical constituents in aqueous form. The study conducted laboratory batch experiments to compare the efficiency of using zero-valent iron in a reducing environment to remediate endocrine disrupting compounds in groundwater. The experimentations looked at varying ratios of volume of solution to mass of zero-valent iron. Furthermore, this study compared the reactions of the chemical constituent in question by varying the aqueous solution to entail the combined constituents (BPA and E2) to separate solutions to determine the chemical degradation model and rates over a period of a week. During the experiments held out with the combined concentration of BPA and E2, both BPA and E2 followed a power-law model. Degradation rates increased as the varying volume to mass ratio decreased. The higher degradation rates were found with a volume to mass solution at 2-1 which gave the chemicals the shortest half-lives. BPA's lowest calculated half-life was approximately 12 days. E2's lowest calculated half-life was approximately 1 day. The degradation rates varied for each EDC when the compounds were treated separately in an aqueous solution over a 24-hour period. The set of experimentations showed that the higher degradation rates occurred with a volume to mass ratio of 2-1. BPA followed the first-order degradation model and showed a reduction of approximately 93% with a calculated half-life of 24 days. E2 followed a pseudo first-order degradation model and showed a reduction of approximately 92% during a 24-hour period with a calculated half-life of 2.655 hours. The research shows that the chemicals are competing for the surface area of the iron when in combined solutions. The experimentations in separate solutions show that E2 is a limiting factor in the ZVI. The research determined that degradation of bisphenol A and 17b-estradiol will occur in an aqueous solution in zero-valent iron.

In today’s chemically dependent society, environmental studies demonstrate that drinking water in developed countries contains numerous industrial chemicals, pesticides, pharmaceuticals and chemicals from water treatment processes. This poses a real threat. As a result of the ever-expanding list of chemical and biochemical products industry, current drinking water standards that serve to preserve our drinking water quality are grossly out of date. Environmental Science of Drinking Water demonstrates why we need to make a fundamental change in our approach toward protecting our drinking water. Factual and circumstantial evidence showing the failure of current drinking water standards to adequately protect human health is presented along with analysis of the extent of pollution in our water resources and drinking water. The authors also present detail of the currently available state-of-the-art technologies which, if fully employed, can move us toward a healthier future. * Addresses the international problems of outdated standards and the overwhelming onslaught of new contaminants. * Includes new monitoring data on non-regulated chemicals in water sources and drinking water. * Includes a summary of different bottled waters as well as consumer water purification technologies.

Endocrine Disrupting Chemicals (EDCs) have been shown to produce changes in the endocrine system of organisms that lead to increases in cancers and abnormalities in reproductive structure and function. Recent research has highlighted the existence of hormonally active compounds in sewage and industrial effluents and their potential for recycling back into the environment - including drinking water supplies- through point sources and non-point sources. Endocrine Disrupters in Wastewater and Sludge Treatment Processes presents the latest research on EDCs, covering the sources, fate, and transport of EDCs in sewage and industrial effluents, and sludge treatment and disposal options in light of effects on receiving environments. In addition, the authors review current legislation, future research needs, and potential management strategies for endocrine disrupters in the environment.

Plant hormone signaling plays an important role in many physiological and developmental processes including stress response. With the advent of new post-genomic molecular techniques, the potential for increasing our understanding of the impact of hormone signaling on gene expression and adaptive processes has never been higher. Unlocking the molecular underpinnings of these processes shows great promise for the development of new plant biotechnologies and improved crop varieties. The topics included in this book emphasize on genomics and functional genomics aspects, to understand the global and whole genome level changes upon particular stress conditions. With the functional genomics tools, the mechanism of phytohormone signaling and their target genes can be defined in a more systematic manner. The integrated analysis of phytohormone signaling under single or multiple stress conditions may prove exceptional to design stress tolerant crop plants in the field conditions. Bringing together the latest advances, as well as the work being done to apply these findings to plant and crop science, Mechanism of Plant Hormone Signaling Under Stress will prove extremely useful to plant and stress biologists, plant biotechnology researchers, as well as students and teachers.

The rise in the incidence of health problems such as reproductive disorders and testicular and breast cancer has been linked by some to endocrine disrupting chemicals in the environment. The role of food in transmitting these chemicals is uncertain and a topic of considerable research. This important book addresses key topics in this area. The first part of the book reviews the impacts of endocrine disrupting chemicals on health and behaviour, with chapters on the effect of dietary endocrine disruptors in such areas as the developing foetus, cancer and bone health. Parts two and three focus on the origin and analysis of endocrine disruptors in food products and risk assessment. Topics addressed include surveillance, analysis techniques such as biosensors, exposure assessment and the relevance of genetics, epigenetics and genomic technologies to the study of endocrine disrupting chemicals. Concluding chapters discuss examples of selected endocrine disrupting chemicals associated with food, such as dioxins, polychlorinated biphenyls and brominated flame retardants, bisphenol A and phytoestrogens and phytosterols. With its distinguished editor and international team of contributors, Endocrine-disrupting chemicals in food is an essential reference for all those concerned with ensuring the safety of food. Reviews the impacts of endocrine disrupting chemicals on health and behaviour including cancer and reproductive disorders Addresses the origin and analysis of endocrine disruptors with chapters on surveillance and analysis techniques Examines the relevance of genetics, epigenetics and genomic technologies to endocrine disrupting chemicals
