This book was released on 2008-08 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2006 in the subject Environmental Sciences, grade: 1,7, Brandenburg Technical University Cottbus, 42 entries in the bibliography, language: English, abstract: The objective of the study is charactering of the primary flux in an enclosure experiment of chemical and/or biological neutralisation in one of the numerous acidified lakes in the Lusatian mining district, (Germany) and tracing the consequences for the water chemistry, reps. water quality. Sedimentation as one of the most important physical process in the water controls the energy flow through aquatic ecosystems thus normally transporting nutrients to the lake bottom. The rate of seston deposition has great importance for understanding the circulation of organic and mineral matter within a lake and can be regarded as a measure of the nutrient recycling there. Acidity removal amendments (soda ash, organic mater and phosphate) added to the enclosures in different combinations resulted in components specific seston fluxes and in changes in the biological and chemical parameters of the water column. It was found that the addition of neutraliser and organic amendments (ENePo) resulted in a flux of authochthonous particulate matter of 6 - 4g/(m d) and enhanced at most and in a long term (in the course of the experiment) the nutrients (P, C, N) cycling and the water quality (as increasing from the bottom pH gradient was observed). The addition of organic matter to the acidic water column (EPo) resulted in similarly enhanced gross sedimentation but with a small time lag compared to the same treatment of the neutralized water as the assimilation of the nutrients was hindered by the low pH (retaining P in the sediment) and the initially low primary production. The addition of phosphates (ENePo, EP) did not result in a long term and self-sustained enhancement of the primary flux as after P being assimilated and transported to the sediment it remained immobilized there, thus the P eleme

Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Download or read book Passive Treatment of Acid Rock Drainage written by Wesley R. Sandlin and published by . This book was released on 2020 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generation of acid rock drainage (ARD) continues to significantly impact water resources around the globe. Passive treatment systems have been developed as lower-cost remediation alternatives to active treatment systems, but seasonality of flow, acidity, and metal concentrations present challenges for passive systems. This thesis examines the limitations of current passive treatment system options and explores the potential of a manufactured silica fiber functionalized with (3-Aminopropyl)triethoxysilane (Si+APTES) and a naturally occurring silicate mineral (clinoptilolite) as reactive substrates for passive treatment of ARD.The first chapter is a review of passive treatment options for acid rock drainage. This review indicates reduced efficacy due to seasonal periods of increased drainage and metal concentrations that lead to mineral precipitation, surface passivation, and flow bypass. In select cases, passive treatment systems prematurely failed due to seasonal flux. Complimentary systems are needed to minimize impacts from seasonal flux of drainage and metal concentrations to improve treatment efficacy and preserve the life of a multi-component system or a downstream primary system. Multi-component systems are possible with integration of existing treatment systems and design of new treatment options to tailor treatment to site specifications. The second chapter explores Si+APTES and clinoptilolite as potential reactive substrates for passive treatment of acid rock drainage. Column permeability experiments with silica fiber and loosely packed clinoptilolite indicate greater permeability and stability of the clinoptilolite. Batch sorption experiments with bare silica fiber, Si+APTES, and clinoptilolite in an Fe-SO4, pH 3.0 solution indicate an Fe specific sorption efficacy of Si+APTES > clinoptilolite > bare silica fiber at equivalent surface areas. Specific sorption values normalized to possible packing densities indicate greater sorption per volume for clinoptilolite. Sorption results for Si+APTES and clinoptilolite did not produce isotherms that could be described by the Langmuir or Freundlich models likely because of surface heterogeneity and precipitation reactions. Column sorption experiments under flowing conditions indicate an Fe removal efficacy of clinoptilolite > Si+APTES for permeable packing densities. Si+APTES demonstrated high specific sorption of Fe in batch sorption experiments and has potential use in low-flow, passive treatment of acid rock drainage. The balance of greater permeability, stability under flowing conditions, large surface area, microporous structure, and ion-exchange properties of clinoptilolite make these zeolite grains a better reactive substrate for passive treatment of acidic drainage in high- or low-flow conditions.
