This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
Download or read book Monitoring Algal Blooms written by Mati Kahru and published by . This book was released on 1997 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The incidence of harmful algal blooms appears to be increasing in European and Asian waters, and along the Atlantic coast. The data available for this observation, however, is patchy, and data for earlier periods is completely non-existent. The traditional technique to identify and monitor phytoplankton includes microscopic examination of water samples collected aboard research vessels. The information provided by this methodology is often limited in temporal and spatial scope because of the limitations of shipboard sampling and the enormous amounts of time and effort which are involved in analyzing the samples. New techniques are required to furnish appropriate information in order to identify and monitor algal blooms. This book explores these new technologies in depth.
Download or read book Toxic Cyanobacteria in Water written by Ingrid Chorus and published by CRC Press. This book was released on 2021-03-08 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacterial toxins are among the hazardous substances most widely found in water. They occur naturally, but concentrations hazardous to human health are usually due to human activity. Therefore, to protect human health, managing lakes, reservoirs and rivers to prevent cyanobacterial blooms is critical. This second edition of Toxic Cyanobacteria in Water presents the current state of knowledge on the occurrence of cyanobacteria and cyanotoxins as well as their impacts on health through water-related exposure pathways, chiefly drinking-water and recreational activity. It provides scientific and technical background information to support hazard identification, assessment and prioritisation of the risks posed by cyanotoxins, and it outlines approaches for their management at each step of the water-use system. It sets out key practical considerations for developing management strategies, implementing efficient measures and designing monitoring programmes. This enables stakeholders to evaluate whether there is a health risk from toxic cyanobacteria and to mitigate it with appropriate measures. This book is intended for those working on toxic cyanobacteria with a specific focus on public health protection. It intends to empower professionals from different disciplines to communicate and cooperate for sustainable management of toxic cyanobacteria, including public health workers, ecologists, academics, and catchment and waterbody managers. Ingrid Chorus headed the department for Drinking-Water and Swimming-Pool Hygiene at the German Environment Agency. Martin Welker is a limnologist and microbiologist, currently with bioMérieux in Lyon, France.

Download or read book Global Ecology and Oceanography of Harmful Algal Blooms written by Patricia M. Glibert and published by Springer. This book was released on 2018-04-26 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) - blooms that cause fish kills, contaminate seafood with toxins, or cause human or ecological health impacts and harm to local economies - are occurring more often, in more places and lasting longer than in past decades. This expansion is primarily the result of human activities, through increased nutrient inputs and various aspects of climate change. The Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) programme promoted international collaboration to understand HAB population dynamics in various oceanographic regimes and to improve the prediction of HABs. This volume introduces readers to the overarching framework of the GEOHAB programme, factors contributing to the global expansion of harmful algal blooms, the complexities of HABs in different habitats, and the forward-looking issues to be tackled by the next generation of GEOHAB, GlobalHAB. The programme brought together an international team of contributing scientists and ecosystem managers, and its outcomes will greatly benefit the international research community.

Download or read book Algal Toxins Nature Occurrence Effect and Detection written by Valtere Evangelista and published by Springer Science & Business Media. This book was released on 2008-06-27 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures and seminars given at the NATO Advanced Study Institute on “Sensor Systems for Biological Threads: The Algal Toxins Case”, held in Pisa, Italy in October, 2007. The Institute was sponsored and funded by the Scientific Affairs Division of NATO. It is my pleasant duty to thank this institution. This ASI offered updated information on how far the research on algal toxins has gone in the exploration of structures, biosynthesis and regulation of toxins, and the development of technology for bio-monitoring these c- pounds. Algae can form heavy growths in ponds, lakes, reservoirs and sl- moving rivers throughout the world; algae can house toxins which are - ually released into water when the cells rupture or die. Hundreds of toxins have been identified so far. Detection methods, including rapid screening, have been developed to help us learning more about them, especially to find out which toxins are a real threat for people and what conditions encourage their production and accumulation. Early detection of algal toxins is an - portant aspect for public safety and natural environment, and significant efforts are underway to develop effective and reliable tools that can be used for this purpose.
Download or read book Advances in Monitoring and Modelling Algal Blooms in Freshwater Reservoirs written by Inchio Lou and published by Springer. This book was released on 2016-10-08 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes essential principles of and approaches to monitoring and modeling algal blooms. Freshwater algal blooms have become a growing concern worldwide. They are caused by a high level of cyanobacteria, particularly Microcystis spp. and Cylindrospermopsis raciborskii, which can produce microcystin and cylindrospermopsin, respectively. Since long-term exposure to these cyanotoxins may affect public health, the reliable detection and quantification of these harmful algae species has become a priority in water quality management. The book utilizes an advanced monitoring approach to identify and quantify cyanobacteria species and various cyanotoxin-producing genotypes. Further, it uses a modeling approach to forecast the occurrence of the phytoplankton that causes algal blooms in freshwater reservoirs, providing a comprehensive picture of currently available micro- and macro-techniques for studying the problem of algal blooms. As such, it offers a valuable guide for researchers, graduate students and professional engineers engaged in monitoring and modeling water quality in lakes and reservoirs.

Download or read book Development of Monitoring and Treatment Technologies to Combat Harmful Algae Blooms written by Shardula Gawankar and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Erie has been affected by harmful algal blooms for decades. In 2014, this resulted in the plant having to shut down its intake after toxic cyanotoxins were found in source water. Such occurrences are becoming more common across the globe. U.S. EPA has established regulations for microcystin, the most common form of cyanotoxin. Climate change is predicted to increase the occurrence of other types of cyanotoxins, such as saxitoxins, which are not regulated by the U.S. EPA. Hence, the removal and monitoring of cyanotoxins, produced by harmful algae blooms, in water is of utmost importance to protect public health.The efficacy of oxidation varies greatly for each of the cyanotoxins due to their different chemical structures. There is presently no oxidation process that a water treatment plant can implement that is proven to simultaneously remove all the cyanotoxins (microcystin, saxitoxin, cylindrospermopsin, and anatoxin) from drinking water. Thus, water treatment plants that are currently designed to remove microcystins are not protected against all forms of cyanotoxins. The investigation of the removal of these cyanotoxins using innovative treatment technologies requires a detection method that is sensitive and capable of detecting all the variants of cyanotoxins. The detection of saxitoxin is particularly challenging as compared to other cyanotoxins due to its low molecular mass and highly polar nature. Hydrophilic interaction liquid chromatography coupled with mass spectrometry (HILIC-MS) has the ability to provide specific detection through mass differentiation, which makes it an ideal tool for the quantitative analysis of saxitoxin and its variants. Hence, a method was developed to extract and detect saxitoxin from water using HILIC-MS in conjunction with weak cation exchange solid phase extraction (SPE), to provide a sensitive and reliable quantification of saxitoxins. However, the application of LC/MS for the detection of cyanotoxins in treatment studies is not cost effective as the cost of instrumentation is high, its operation requires high skill, and cyanotoxin standards have limited access and are expensive. Hence, a screening technique has been developed which uses methylene blue to identify the reaction kinetics of persulfate and peroxide oxidation in the presence of ferrous chloride and to optimize parameters, which can be helpful in predicting the degradation of cyanotoxins under similar conditions. Catalyst activated persulfate and peroxide oxidation produce sulfate and hydroxyl radicals, which can degrade a wide range of recalcitrant chemicals and hence are preferred in water and wastewater treatment. The screening technique was validated by investigating the degradation of microcystin-LR. The notable advantages of developing this screening technique are: (i) reduced cost of analysis as methylene blue can be detected in real time by measuring its absorbance, and (ii) can perform multiple trials in short time due to ease of analysis. This screening technique was also applied to iron oxide coated ceramic membranes in combination with persulfate oxidation to understand the degradation kinetics.
