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 Cyanotoxins written by Ingrid Chorus and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 374 pages. 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.

Download or read book Cyanobacterial Toxins of Drinking Water Supplies written by Ian Robert Falconer and published by CRC Press. This book was released on 2004-12-20 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contamination of both drinking and recreational water supplies by cyanobacteria is increasingly a cause for concern worldwide. While contamination causes livestock deaths with relative frequency, acute poisoning is rare in humans. However, there is growing apprehension over the possible role of cylindrospermopsins and microcystins in gastrointestinal and liver cancer. Cyanobacterial Toxins of Drinking Water Supplies provides an articulate account of the biology, chemistry, toxicology, and human health implications of cylindrospermopsins and microcystins, and their occurrence in water supplies. It discusses effective methods of prevention, mitigation, and remediation of cyanobacterial blooms in reservoirs. The book presents novel and traditional approaches to water treatment for the elimination of these toxins. Written by a renowned expert who plays an instrumental role in revising the World Health Organization’s drinking water guidelines for cyanotoxins, the book uses the field’s most relevant findings and current examples to support a practical approach for assessing the potential risks and costs from toxic cyanobacterial blooms in water supplies. Cyanobacterial Toxins of Drinking Water Supplies provides a lucid analysis of present and emerging issues in the ecology, safety, and treatment of drinking water for in environmental agencies, researchers, and policymakers. It is an authoritative resource for professionals in drinking and recreational water management, water supply utilities, analytical laboratories, and public health offices.
Download or read book Second Assessment of Climate Change for the Baltic Sea Basin written by The BACC II Author Team and published by Springer. This book was released on 2015-04-03 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.

Download or read book Relationship Between Toxic Cyanobacterial Blooms Psycho chemical Factors and Multiple Source Excreta Contamination in Affected Watershed written by Valentina Muñoz Ramos and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Missisquoi Bay (MB) is a temperate eutrophic freshwater ecosystem located in an agricultural watershed and it frequently experiences toxic Microcystis-dominated cyanobacterial blooms. Cyanobacterial population dynamics are influenced by a plethora of factors that may differ from system to system, requiring a site-specific assessment of bloom-promoting factors to design more effective bloom prevention or remediation strategies. This is the first biomonitoring study that combined data from high-throughput 16S rRNA gene amplicon sequencing, qPCR and environmental parameters from temporal and spatial samples to identify the main bloom-promoting factors. In addition, high-throughput amplicon sequencing of mitochondrial DNA genes was performed to qualitatively identify potential external sources of nutrients originating from animal excreta. Particular emphasis was placed on 1) determining whether there was a link between nutrients from external sources and cyanobacterial blooms and 2) analyzing in situ the effect of environmental factors (particularly nitrogen (N) and phosphorus (P) concentrations) on the dynamics of cyanobacterial community composition, abundance and toxicity.The concentrations of total P (TP) and total N (TN) in MB in 2009 correlated significantly with the abundance of total cyanobacterial cells, the Microcystis 16S rRNA and mcyD genes and intracellular microcystin. The results suggest that external sources of nutrients, such as surface runoff and animal excreta, played a significant role in the load of nutrients into the bay and thus in the proliferation of toxic cyanobacterial blooms. This was indicated by the detection of non-aquatic mitochondrial DNA hosts in the bay and the relationships between the pattern of surface runoff, nutrient concentrations, E. coli counts and total cyanobacterial abundance. Potential sources of nutrients from non-aquatic animal excreta in the system comprised rodents, birds, cattle and humans, indicating that efforts are required to control pollution from animal excreta in MB. During the growing season, the major cyanobacterial taxa were members of the orders Chroococcales and Nostocales. The genus Microcystis was identified as the main mcyD-carrier and main microcystin producer, hence the most problematic taxon in the cyanobacterial bloom. The correlations observed with environmental parameters suggest that increasing nutrient concentrations and TN:TP (mass) ratios approaching 11:1, coupled with an increase in temperature, promoted Microcystis-dominated toxic cyanobacterial blooms. Although the importance of nutrient ratios and absolute concentrations on cyanobacterial and Microcystis dynamics has been documented, this is the first time that an optimum TN:TP ratio for Microcystis dominance has been observed in the field. This observation provides further support to the theory that nutrient supply ratios are an important determinant of species composition in natural phytoplankton assemblages. Although the validity and prediction potential of this optimum ratio for Microcystis dominance has yet to be verified through longer-term studies, it may provide practical guidelines for nutrient management strategies to avoid the proliferation of this toxin producing cyanobacterial genus in MB.
