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
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 Description
With the ever-increasing incidence of harmful cyanobacterial algal blooms, this monograph has added urgency and will be essential reading for all sorts of researchers, from neuroscientists to cancer research specialists. The volume contains the proceedings of the 2005 International Symposium on Cyanobacterial Harmful Algal Blooms, and has been edited by H. Kenneth Hudnell, of the US Environmental Protection Agency. It contains much of the most recent research into the subject.

Book Description
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.

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
Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. This single volume brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments). In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. Accordingly, this new edition covers updated classification information of most algal groups and the reassignment of many genera and species, as well as new research on harmful algal blooms. - Extensive and complete - Describes every genus of freshwater algae known from North America, with an analytical dichotomous key, descriptions of diagnostic features, and at least one image of every genus. - Full-color images throughout provide superb visual examples of freshwater algae - Updated Environmental Issues and Classifications, including new information on harmful algal blooms (HAB) - Fully revised introductory chapters, including new topics on biodiversity, and taste and odor problems - Updated to reflect the rapid advances in algal classification and taxonomy due to the widespread use of DNA technologies

Book Description
This paper provides an extensive review of different aspects of five shellfish-poisoning syndromes (paralytic, diarrhoeic, amnesic, neurologic and azapiracid), as well as one fish-poisoning syndrome (ciguatera fish poisoning). It discusses in detail the causative toxins produced by marine organisms, chemical structures and analytical methods, habitat and occurrence of the toxin-producing organisms, case studies and existing regulations. Based on this analysis, risk assessments are carried out for each of the toxins, and recommendations are elaborated to improve the management of these risks in order to reduce the harmful effects of these toxins on public health.
