Download or read book Marine and Industrial Biofouling written by Hans-Curt Flemming and published by Springer Science & Business Media. This book was released on 2008-12-11 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofouling is a costly problem, and it is encountered in a wide spectrum of technical systems, ranging from the shipping industry, power industry, water purification, automobile industry, paint and pharmaceuticals, to the microelectronics and food industries. Micro- and macroorganisms attach to surfaces and accumulate there, forming biofilms that cause interferences – a fundamentally natural process. Usually, a medical paradigm is applied: kill biofilms and the problem is solved. This leads to excessive biocide use. However, the success of this strategy is very limited; furthermore it leads to equipment damage and environmental pollution. Simply trying to kill the fouling organisms is clearly not seen as a successful strategy while cleaning is put forward as much more important. In this book, strategies to prevent adhesion, to mitigate the extent and effects of biofouling, and to detect and remove fouling layers are presented. Holistic approaches to the fouling process are elaborated, taking into account options such as nutrient limitation, repellent and easy-to-clean surfaces for fouling layer limitation, and replacing biocides with more environmentally friendly methods – in other words: learning how to live with fouling biofilms without suffering the damage they can do.
Download or read book Human Pharmaceuticals Hormones and Fragrances written by Thomas Ternes and published by IWA Publishing. This book was released on 2007-01-30 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: The observed concentrations of pharmaceuticals and personal care products (PPCPs) in raw wastewater confirm that municipal wastewater represents the main disposal pathway for the PPCPs consumed in households, hospitals and industry. In sewage treatment plant effluents most PPCPs are still present, since many of these polar and persistent compounds are being removed only partially or, in some cases, not at all. Treated wastewater therefore represents an important point source for PPCPs into the environment. After passing a sewage treatment plant the treated wastewater is mostly discharged into rivers and streams or sometimes used to irrigate fields. If drinking water is produced using resources containing a substantial proportion of treated wastewater (e.g. from river water downstream of communities) the water cycle is closed and indirect potable reuse occurs. Human Pharmaceuticals, Hormones and Fragrances provides an overview of the occurrence, analytics, removal and environmental risk of pharmaceuticals and personal care products in wastewater, surface water and drinking water. The book covers all aspects of the fate and removal of PPCPs in the whole water cycle: consumption and occurrence, analytical methods, the legal background, environmental risk assessment, human and animal toxicology, source control options, wastewater and drinking water treatment as well as indirect reuse. The book presents a summary of the results obtained during the EU project "Poseidon", combined with further expert knowledge on the field, and is written at a level appropriate for professionals involved in management of water resource quality. Professionals in the field including decision makers, engineers and scientists, as well as students entering the field, will find this an invaluable source of information. First comprehensive study on the assessment, fate and removal of pharmaceuticals and personal care products in wastewater and drinking water treatment. Emphasises the importance of micropollutants in the water cycle, provides methods for quantifying their fate and technologies for their removal.
Download or read book Elements of Marine Ecology written by R. V. Tait and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widening interest in marine biology has led to the establishment of an increasing number of school and undergraduate courses in the subject. There are many books on various aspects of marine biology which students can read with advantage, but few that are suitable as introductory reading at the commencement of studies. This book has been compiled primarily as an aid for zoology students at the start of a special course on marine biology. The text is an introduction to the author's annual course for undergraduates. The aim has been a concise presentation of information and ideas over the general field of marine ecology, with guidance on the selection of more advanced reading. The sources of further information given at the end of each chapter have been chosen as far as possible from books and journals to which students should have reasonably easy access. These lists provide a selection of additional reading which starts at an elementary level and be comes more advanced as the course proceeds. Students entering the author's course are usually in their third under graduate year, and a general knowledge of the phyla is therefore assumed.

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 Psychiatric Pharmaceuticals as Emerging Contaminants in Wastewater written by Bruna Silva and published by Springer. This book was released on 2015-06-25 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how psychiatric pharmaceuticals, namely antidepressants, anxiolytics, sedatives and hypnotics are among the most prescribed active substances due to the higher occurrence of psychiatric disorders throughout the world. It goes on to demonstrate how patients’ excretion of the active compounds along with several metabolites is considered to be the main pathway for the occurrence of these emerging pollutants in wastewater treatment plant effluents, surface and drinking water, soils and sediments. Further chapters are devoted to an exploration of these pharmaceuticals’ high persistence, toxicity and intrinsic biological activity, which can affect the nervous and endocrine systems of terrestrial and aquatic non-target organisms, the dissemination of these compounds in environment matrices and the growing number of associated problems and concerns. The remainder of the book describes how conventional wastewater treatment processes are generally inefficient when it comes to the removal of this type of pollutants, giving rise to the demand for implementing alternative or complementary treatment technologies. Extensive research studies on the efficiency of the degradation and/or removal of these pollutants are summarized, and adsorption, membrane and advanced oxidation processes (AOP) are proposed. Given its content and structure, the book offers a concise summary of the most significant findings on psychiatric pharmaceutical removal in wastewater.
Download or read book Effect of High Temperature on Crop Productivity and Metabolism of Macro Molecules written by Amitav Bhattacharya and published by Academic Press. This book was released on 2019-06-14 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effect of High Temperature on Crop Productivity and Metabolism of Macro Molecules presents a comprehensive overview on the direct effect of temperatures defined as "high", a definition which increasingly includes a great number of geographic regions. As temperature impacts the number of base growth days, it is necessary to adapt plant selection, strategize planting times, and understand the expected impact of adaptive steps to ensure maximum plant health and crop yield. Global warming, climate change and change in environmental conditions have become common phrases in nearly every scientific seminar, symposium and meeting, thus these changes in climatic patterns constrain normal growth and reproduction cycles. This book reviews the effect of high temperature on agricultural crop production and the effect of high temperature stress on the metabolic aspects of macro molecules, including carbohydrates, proteins, fats, secondary metabolites, and plant growth hormones. Focuses on the effects of high temperature on agriculture and the metabolism of important macro-molecules Discusses strategies for improving heat tolerance, thus educating plant and molecular breeders in their attempts to improve efficiencies and crop production Provides information that can be applied today and in future research

Download or read book Bioorganic Marine Chemistry written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present series, "Bio-organic Marine Chemistry," is being launched at a time when we have the fundamental knowledge and the requisite instrumentation to probe the molecular basis of many biological phenomena. The final volume of "Marine Natural Products-Chemical and Biological Perspectives" (Academic Press), which may be con sidered the precursor of this series, was published in 1983. In that series, which I edited, primary emphasis was placed on molecular structure and phyletic relationships. This focus was compatible with the major concerns of a growing research community in the field of marine natural products. Moreover, a need existed for timely reviews of a rapidly expanding and widely scattered primary literature. As I read again the Preface to Volume 1 (1978), I am amazed at the changes in direction and emphasis which have taken place during these few intervening years. Sufficient basic data are now at hand to gauge the breadth of the marine natural product spectrum and to raise questions of functions, both within and outside the marine ecosystem. Although we have few answers, the questions have become meaningful and pointed. Furthermore, the task of tracking and cataloguing the steady stream of fascinating new structures has been assumed by Faulkner's periodic surveys in Natural Product Reports, a bimonthly publication of the Royal Society of Chemistry. The study of marine natural products remains firmly anchored in chemistry, i. e. in molecular integrity, yet continues to seek greater involvement in functional biology.

Download or read book Marine Algal Bloom Characteristics Causes and Climate Change Impacts written by Santosh Kumar Sarkar and published by Springer. This book was released on 2018-05-02 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.
