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 Toxic Blue-green Algae written by Great Britain. National Rivers Authority and published by Stationery Office Books (TSO). This book was released on 1990 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 1989, dogs and sheep died at Rutland Water following the ingestion of a scum of toxic blue-green algae. The NRA therefore undertook the first major national appraisal of blue-green algae throughout England and Wales. Their report describes the results of the 1989 survey and looks at how events were managed. Recommendations are made for future management, monitoring, research and development. It also reviews blue-green algal toxins, the factors which affect blue-green algal bloom production and approaches to controlling algal populations.

Book excerpt: Toxic Algae is an epidemic threatening natural waterways locally, and globally. Harmful Algal Blooms (HAB) are an explosive growth of photosynthetic organisms in a body of water which can harm amphibians, fish, wildlife, pets, and human health by producing dangerous toxins. Fresh water systems such as ponds, lakes, rivers, and reservoirs are under assault from many directions increasing chemical imbalance stressing the aquatic water systems ability to stay in healthy balance. Toxic Algae in Harmful Algal Blooms (HAB) are an increasing threat to waterways throughout the country, and are reported with greater frequency in all 50 states. The water quality of our Ponds, Lakes, Rivers and Reservoirs are of prime importance to local communities, and the general health of local environments and ecosystems globally. Used for recreation, and as a food source for millions of people worldwide, healthy waterways are vital for ecosystems and people everywhere. Cyanobacteria are a photosynthetic bacteria which is normally a very productive part of the aquatic ecosystem. However, when Cyanobacteria "break bad" then very harmful toxins can be produced by some species which can be highly dangerous. Stressed from nutrient loading events such as a storm run-off, natural water bodies are being stressed to the point of imbalance introducing invasive species - including Toxic Algae. Cyanobacteria (called a Blue-Green Algae) are a type of photosynthetic bacteria. When a pond, lake, stream, river, or other water body experiences a "nutrient loading event" conditions can trigger an algal bloom which may result in a Harmful Algal Bloom (HAB). This book examines the causes of Harmful Algal Blooms (HAB) in fresh water systems, and explores methods used to combat the triggers of HAB. As climate change, population growth, and intensified agriculture and animal feeding operations grow the potential for increased frequency and toxicity of Harmful Algal Blooms (HAB) increases exponentially, and represents a real danger to water bodies, aquatic ecosystems, wildlife, livestock, pets and people everywhere. This book discusses how to treat and prevent Harmful Algal Blooms (HAB) providing a means of protecting your pond, lake, river, or reservoir from Toxic Algae.

Download or read book The Water Environment written by Wayne Carmichael and published by Springer. This book was released on 2013-06-14 with total page 491 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 Guidelines on recreational water quality. Volume 1 written by World Health Organization and published by World Health Organization. This book was released on 2021-07-12 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
