Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Use of coastal, estuarine and freshwater recreational environments has significant benefits for health and well-being, including rest, relaxation, exercise, cultural and religious practices, and aesthetic pleasure, while also providing substantial local, regional and national economic benefits. These guidelines focus on water quality management for coastal and freshwater environments to protect public health. The guidelines: 1. describe the current state of knowledge about the possible adverse health impacts of various forms of water pollution; and2. set out recommendations for setting national health-based targets, conducting surveillance and risk assessments, putting in place systems to monitor and control risks, and providing timely advice to users on water safety.These guidelines are aimed at national and local authorities, and other entities with an obligation to exercise due diligence relating to the safety of recreational water sites. They may be implemented in conjunction with other measures for water safety (such as drowning prevention and sun exposure) and measures for environmental protection of recreational water use sites.

Book Description
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.

Book Description
Harmful Algal Blooms: A Compendium Desk Reference provides basic information on harmful algal blooms (HAB) and references for individuals in need of technical information when faced with unexpected or unknown harmful algal events. Chapters in this volume will provide readers with information on causes of HAB, successful management and monitoring programs, control, prevention, and mitigation strategies, economic consequences of HAB, associated risks to human health, impacts of HAB on food webs and ecosystems, and detailed information on the most common HAB species. Harmful Algal Blooms: A Compendium Desk Reference will be an invaluable resource to managers, newcomers to the field, those who do not have easy or affordable access to scientific literature, and individuals who simply do not know where to begin searching for the information needed, especially when faced with novel and unexpected HAB events. Edited by three of the world's leading harmful algal bloom researchers and with contributions from leading experts, Harmful Algal Blooms: A Compendium Desk Reference will be a key source of information for this increasingly important topic.
