Download or read book Freshwater Algal Toxins written by Angeles Jos and published by MDPI. This book was released on 2020-12-11 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacterial abundance has increased disproportionately, and this trend is likely to continue in the coming decades. This increase not only has deleterious effects on ecosystem biodiversity but also adversely affects drinking water supplies, livestock watering, crop yields, aquaculture, etc. Thus, the proliferation of cyanobacterial blooms presents human and animal health risks due to the common production of potent toxins, cyanotoxins. Moreover, these risks are aggravated by the accumulation potential of cyanotoxins and their transference to the food chain. In spite of the worldwide increasing occurrence of cyanotoxins, they are still underestimated in regulations. However, risk management of cyanotoxins is only possible after a thorough risk evaluation, and for that purpose, toxicity and exposure data are required. Thus, occurrence and monitoring information is of key importance, and new data in relation to the conditions that favor cyanobacterial growth and cyanotoxin production are welcome in order to prevent their appearance. On the other hand, in regard to toxicity, there are still many data gaps to fill. This book compiles 10 research papers and a review, which provide valuable contributions on all these aspects and demonstrate the importance of cyanobacteria toxins research.
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 Harmful Algae Blooms in Drinking Water written by Harold W. Walker and published by CRC Press. This book was released on 2014-12-18 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) occurring in freshwater, and the associated toxins they produce, are dangerous to animals and humans. Mitigating the increasing presence of HABs presents a major challenge to water managers and drinking water utilities across the world. This book explores the current research on removal of HABs and toxins from drinking water. It provides the necessary tools so that treatment plant operators, engineers, and water managers can understand the vulnerability of drinking water treatment plants to HABs and develop treatment processes to minimize the impact of these contaminants. Although conventional treatment processes can be effective for the removal of HAB cells and some HAB toxins under optimal conditions, the potential exists for significant breakthrough of toxins during normal operation. As a result, there is a recognized need for more advanced techniques. Possible advanced processes for removing HAB toxins include granular activated carbon (GAC), powdered activated carbon (PAC), or oxidative processes. This book reviews both conventional and advanced treatment processes and presents clear and easy-to-understand procedures for the design of systems for optimal cell or toxin removal.

Download or read book The Water Environment written by Wayne Carmichael and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conference on The Water Environment: Algal Toxins and Health was held at Wright State University in Dayton, Ohio, on June 29, 30, July 1, 2, 1980. Its principal objectives were to bring together, for the first time, researchers, public officials and interested parties in order to present and discuss what is known about algal toxins. The conference concentrated almost exclusively on toxins and toxic blooms of blue-green algae (Cyanobacteria). Since the most common Cyanobacteria bloom forming species are also the ones most likely to produce toxins, they are a problem in the maintenance of safe animal and human water supplies. While poison ings by Cyanobacteria involve mainly domestic and wild animals, they may also be responsible for cases of human gastroenteritis and con tact poisoning. Even though human poisonings by Cyanobacteria have historically not been a widespread problem, continued deterioration of our recreational and municipal water supplies suggests that blooms of non-toxic and toxic Cyanobacteria blooms will increase. In addi tion to studies on their role as disease agents, there is basic research being done on their pharmacological properties to determine their mode of action and usefulness as tools in the study of basic neuromuscular mechanisms. These papers were centrally typed for reproduction as camera ready copy. Each paper was reviewed and edited by at least two per sons of the editorial committee. This volume is organized into five major sections: 1.

Download or read book Cyanobacteria and Cyanotoxins written by Ana M. Cameán and published by MDPI. This book was released on 2020-04-15 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacteria are a group of ubiquitous photosynthetic prokaryotes. Their occurrence has been increasing worldwide, due to anthropogenic activities and climate change. Several cyanobacterial species are able to synthesize a high number of bioactive molecules, among them, cyanotoxins (microcystins, cylindrospermopsin, nodularin, etc.), which are considered a health concern. For risk assessment of cyanotoxins, more scientific knowledge is required to perform adequate hazard characterization, exposure evaluation and, finally, risk characterization of these toxins. This Special Issue “Cyanobacteria and Cyanotoxins: New Advances and Future Challenges” presents new research or review articles related to different aspects of cyanobacteria and cyanotoxins, and contributes to providing new toxicological data and methods for a more realistic risk assessment.
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.
