Book Synopsis Dissolved Organic Matter Percolated from Periphyton in the Everglades: Characterization and Interaction with Mercury by : Afia Anjuman
Download or read book Dissolved Organic Matter Percolated from Periphyton in the Everglades: Characterization and Interaction with Mercury written by Afia Anjuman and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: When organic matters of various kinds decompose partially, dissolved or soluble organic matters can form. The organic matters are usually produced from plants, soil, bacteria, algae, and living organisms. The wetland of Everglades is rich in dissolved organic matters. The quantity and quality of these dissolved organic matters have significant impact on environmental factors such as biogeochemical activity, transport, absorption, complexation, and more specifically the speciation and geochemical cycling of toxic metals such as mercury (Hg). Everglades wetland is abundant in periphyton which can also be responsible for dissolved organic matter percolation and production. The DOM from periphyton, in particular when freshly produced and released into the water, would have a profound effect on mercury species present in the water, e.g., by forming mercury-DOM complexes. This experiment is designed to perform quantitative and qualitative analysis of DOM produced by periphyton and the complexation of mercury with the produced DOM from periphyton in molecular level. In addition to organic carbon analysis, the samples will be analyzed for optical properties by using a spectrofluorometer for information on the sources, types, and reactivity of DOM. Studies will be done with addition of inorganic and methyl mercury of different concentrations in leached DOM samples from different types of periphyton by observing fluorescence quenching for Hg-DOM complexation using 3D Excitation Emission Matrices Fluorescence Spectroscopy. Water samples from different types of periphyton will be differentiated by measuring different functional groups of DOM; such as total protein, carbohydrates, and thiols; including Chlorophyll-a and nutrients quantitatively using some standard protocols. Measurement of specific types of DOM from periphyton quantitatively will be performed by observing periphyton biomass response for interaction with mercury using Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy. The project will improve the understanding of the relation between DOM and periphyton and the environmental processes of Hg impacted by periphyton in the Florida Everglades.
Book Synopsis Mercury and the Everglades. A Synthesis and Model for Complex Ecosystem Restoration by : Darren G. Rumbold
Download or read book Mercury and the Everglades. A Synthesis and Model for Complex Ecosystem Restoration written by Darren G. Rumbold and published by Springer Nature. This book was released on 2019-11-30 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book integrates 30 years of mercury research in the Florida Everglades to inform scientists and policy makers. The Everglades is an iconic ecosystem by virtue of its expanse; diversity of biota; and multiple international designations. Despite this, the Everglades has been subjected to multiple threats including: habitat loss, hydrologic alterations, invasive species and altered water quality. Less well recognized as a threat to Everglades human use and wildlife populations is the toxic metal, mercury. The first half of Volume II focuses on biogeochemistry and factors unique to the Everglades that make it extraordinarily susceptible to mercury methylation following its deposition: warm subtropical climate, shallow depth, high levels of dissolved organic matter, sulfate contamination, nutrient enrichment and sediment redox conditions (for review of atmospheric mercury deposition significance, see Vol. I). The second half of Volume II answers the “so what” question – why biomagnification of the methylmercury produced in the Everglades is a threat to the health of top predators including humans. The results of the synthesis presented in Volume II suggest that the mercury problem in the Florida Everglades is one of the worst in the world due to its areal extent and the degree of risk to ecological receptors and humans.

The coverage discusses the environmental behavior and toxicological effects of mercury on organisms, including humans, and provides case studies at the end of each chapter. Bringing together information normally spread across several books, this text is unique in covering the entire mercury cycle and providing a baseline for what is known and what uncertainties remain in respect to mercury cycling.
Book Synopsis Mercury and the Everglades. A Synthesis and Model for Complex Ecosystem Restoration by : Curtis D. Pollman
Download or read book Mercury and the Everglades. A Synthesis and Model for Complex Ecosystem Restoration written by Curtis D. Pollman and published by Springer Nature. This book was released on 2020-11-28 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the final installation in a three-volume series synthesizing 30 years of mercury research in the Florida Everglades. The first part of this book evaluates the occurrence of trends in both biota mercury concentrations and atmospheric mercury deposition. Through both empirical and deterministic analyses, the likely drivers of biota trends are identified. These analyses help lay the predicate for devising an overall strategy to mitigate and manage the Everglades mercury problem. The book concludes with a model analysis of the likely benefits and uncertainty attendant with implementing the leading candidate strategy for best reducing the Everglades mercury problem.

Book Synopsis Ecology of Humic Substances in Freshwaters by : Christian Steinberg
Download or read book Ecology of Humic Substances in Freshwaters written by Christian Steinberg and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humic Substances color all waters more or less brown. Their concentrations exceed all carbon of living organisms by at least one order of magnitude. Opposite to former paradigms, they participate in almost any metabolic pathway. They protect against UV-irradation, enable indirect photolysis and, thus, purify hazardous chemicals, they provide inorganic and organic nutrients, may form cryptic genes with DNA and dampen metabolic fluctuations. More recently they can increase adverse effects of hazardous chemicals and they can directly interfere with organisms. The book tries to relate effects to structural features.
Book Synopsis Mercury in the Environment by : Michael S. Bank
Download or read book Mercury in the Environment written by Michael S. Bank and published by Univ of California Press. This book was released on 2012-05-31 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mercury deposition and contamination is widespread and well documented, and it continues to be a public-health concern for certain sectors of the global human population in both developed and developing countries. This edited volume focuses on integrating the diverse sciences involved in the process of mercury cycling in the environment--from the atmosphere, through terrestrial and aquatic food webs, and human populations--to develop a comprehensive perspective on this important environmental pollutant. Using a systems-level approach, this book provides recommendations on mercury remediation, risk communication, education, and monitoring. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly, expanding into several interdisciplinary fields and encompassing such disparate academic and scientific disciplines as biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists really begun to establish more holistic approaches to studying mercury pollution, giving rise to investigations that have furthered the integration of a multi-tiered approach, especially by using chemistry, biology, and human health sciences collectively. The study of mercury pollution has produced a variety of contributions to domestic and international policies related to the management of mercury in the environment"-- Provided by publisher.

This book was released on 2012-12-15 with total page 919 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoinduced processes, caused by natural sunlight, are key functions for sustaining all living organisms through production and transformation of organic matter (OM) in the biosphere. Production of hydrogen peroxide (H2O2) from OM is a primary step of photoinduced processes, because H2O2 acts as strong reductant and oxidant. It is potentially important in many aquatic reactions, also in association with photosynthesis. Allochthonous and autochthonous dissolved organic matter (DOM) can be involved into several photoinduced or biological processes. DOM subsequently undergoes several physical, chemical, photoinduced and biological processes, which can be affected by global warming. This book is uniquely structured to overview some vital issues, such as: DOM; H2O2 and ROOH; HO•; Degradation of DOM; CDOM, FDOM; Photosynthesis; Chlorophyll; Metal complexation, and Global warming, as well as their mutual interrelationships, based on updated scientific results.
