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 Cyanotoxin Removal in Drinking Water Treatment Processes written by Verna J. Arnette and published by . This book was released on 2009 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacteria are prokaryotic microorganisms that are present in many environments. The presence of certain genera of cyanobacteria in aquatic systems is of great concern due to potential toxin formation and release. Cyanotoxins have been shown to have undesirable health impacts ranging from acute (skin irritation, gastrointestinal, and neurotoxic) to chronic (liver damage, kidney damage, and possible carcinogenic) effects. The toxins exist in different structural forms, such as alkaloids (anatoxin-a, saxitoxins, cylindrospermopsin) and cyclic peptides (microcystins, nodularin). Current knowledge and occurrence data of cyanotoxins have led to increased regulatory attention for limiting concentrations in water. The purpose of this paper is to review available literature and knowledge on the potential of drinking water treatment processes to remove cyanotoxins. The main mechanisms of contaminant removal in water are: physical (sedimentation, filtration, flotation, adsorption), chemical (oxidation), and biological. These processes may work singularly or in conjunction to accomplish reduction of the target compound. For cyanotoxins, removal efficiency is complicated by the fact that the toxins exist in two forms: intracellular and extracellular (dissolved). If contained within the cell, physical removal processes would likely be the best form of treatment. Once released from the cell, dissolved toxins may require additional treatment. Evaluation of the literature reviewed indicates that many common drinking water treatment processes are capable of removal or degradation of cyanotoxins. A key point when considering treatment for cyanotoxin removal is the form of the toxin (intracellular or extracellular) with respect to the treatment process being utilized. Physical removal of particulate cyanotoxins, either by sedimentation, floatation, or filtration, has been shown to be successful since cyanobacterial cells are generally well removed. However, sedimentation and filtration do not perform well for dissolved toxin removal, except for certain membrane filtration processes. Adsorption on activated carbon has been shown to reduce cyanotoxins, although contact time and competitive natural organic matter (NOM) can affect performance. Chemical processes (ozone, chlorine dioxide, potassium permanganate, chlorine, chloramines) have a tendency towards cell lysis, and may allow free toxin to enter into the water. Depending on the chemical dose applied, residual toxin may or may not be removed. Therefore, the application point of oxidative chemicals and nature of the toxins are extremely important for cyanotoxin reduction. If applied after filtration, ozone and chlorine have been shown to be the most successful in reducing dissolved cyanotoxins. Chlorine dioxide and chloramines have not been shown to reduce toxin levels. Advanced oxidation processes have shown promise for destruction of dissolved toxins, particularly microcystins. Biological treatment via biologically active filtration (either rapid rate or slow sand), has also been shown to be effective for microcystin reduction, although it must be evaluated carefully to avoid incomplete degradation. Additionally, storage of cyanobacterial cells in treatment processes, hydraulic disturbances, pressure gradients, and recycle of waste streams must be considered to avoid lysis of aging cells and subsequent toxin release. Therefore, not only is proper process application important for toxin removal, optimization of plant operations is critical for sustained toxin reduction.

Available in PDF, EPUB and Kindle. Book excerpt: Toxic cyanobacteria are increasingly recognised as a potential hazard in water for human use. The recent availability of methods for quantitative screening is leading to a surge of research on their occurrence. This book presents a novel compilation of extensive screening results showing the cyanotoxin levels that may be expected when certain taxa dominate. These results indicate cyanotoxins to be the most widespread among the chemicals of concern in water used for drinking and recreation. It further combines field data with results from laboratory culture experiments to suggest a unifying view of how environmental factors control the cyanotoxin levels in natural waters. A practical section is dedicated to the exposure of humans through drinking-water and recreation.

This book was released on 2002 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxic cyanobacteria (blue green algae) have now been reported in 27 countries and are found on all continents including Antarctica. Drinking water authorities world-wide are faced with the challenge of treating contaminated water or the possibility of a toxic bloom occurring sometime in the future. This tailored collaboration project was to provide the international drinking water industry with information to facilitate the confident application of viable treatment techniques for cyanotoxins. Assessment included toxicity of the ozonated solutions, assessment of the protein phosphate inhibition assay technique and the possibility of seeding an activated carbon filter with select bacteria for removal of microcystin-LR. This report offers valuable guidance to the water supplier to aid in deciding upon the most appropriate treatment options for a range of dissolved blue-green algal toxins.

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.
